Great trails for biking and hiking, they also built a bridge that connects to ridge line giving you more space to ride. The incline is really fun and the exercise spot has some good things to do.

The mini-incline and hiking trails are a perfect end of day workout!

Great place for the whole family! Daily admission includes unlimited access to the pool, play structure, turf fields (if not currently in use), and a small gym. Golf simulator and trampolines are extra. Highly recommend getting the 20 punch card for a better price. Kids punch cards are discounted, whereas daily admission is the same as adults. Its a great place for a kids birthday party!

Theres so much to do and see at this amazing facility. Great for kids and adults alike, the ammenities are sure to please. The outdoor playground is unlike any weve ever been to before. We enjoy splashing around in the spray area and hiking the incline. The indoor play area, fields, and pools are just as wonderful. The MAC is an enjoyable place for both locals and tourists.

ITS AWESOME!!!! thats it... just AWESOME

Nice addition to Castle Rock, pool area is nice. A little expensive now, cant let your kid go in unless you go with and pay... trampoline area is good too.

The Miller Activity center (better known as the MAC), is a great place to wear the kids out! Trampolines, and indoor swimming is a sure fire way to make sure the kids are active! During the summer, there are loads more activities to do!

I’ve enjoyed having access to this amazing place. Friendly staff and numerous activities for all ages. My son recently did the Zipline tour and said it was great. I ride the mtb trails around the area weekly. It’s very convenient having such a great facility so close to home.

We went to this place on a field trip for my sons school. Its really a bit of a drive cuz its in Castle Rock , but Im definitely going back to try out the Ziplines! The staff was awesome and the place is really cool for kids of all ages! Swimming pool was warm and they have a very entertaining jungle gym ! No food except vending machines. Golf simulator and weights too.

Soccer Buddies is so fun for teaching fundamentals to young kids! Nice facility, clean and lots of activities.

Very nice pool areas for tons of kids fun. Swimming lessons are available as well.

I take our kids here every week. The free outdoor playground is awesome. My kids dig around in the large sandbox for hours. Also, the ropes area has a large slide with enough turns to keep the speed safe. There is a large spiderweb ropes area where my 8 year old climbs, too.

Great facility. They have pretty much anything you can think to do. Great staff as well!

I always come here and use the outside fitness area (the stairs, hiking) and I thought how great it would be to check out whats inside of the building. Well the young lady at the front desk was not very friendly. I asked her if she had a flyer regarding the services they offer and the entire time she just kept saying this place is for kids and literally before I could say anything she would repeat herself this is a kids place. You have lost my business. Btw, i have 2 kids, which she could have asked. But nope she didnt.

Admission prices are expensive and they charge parents just to watch kids on the play structure and the tramp and the pool! But my child loves this place and if you live in Castle Rock or will be here all day its worth it to come in the morning because you can leave and come back anytime til they close. Birthday parties are reasonable.

Fantastic facilities and staff. Had a birthday party here & continue to return on a monthly basis. Great for kids of all ages!

Fun place for kids, but they have changed their policy and now parents are required to pay simply to sit at the tables while the kids actually use the facility.

Everything about this place is awesome.

This place only spends its energy on making as much money as possible. You have to pay an expensive price to get to be on their trampolines. And if youre lucky its quiet. If you go on a Saturday afternoon, youll find yourself waiting in line forever while the employee in charge lets in their favorites. And if you then are not in the mood for trampolines, then you must pay a fee to get on the play structure. There was an incident where someone got reamed for not paying even though they payed for the trampolines. Overall, save your money and your sanity and just do the incline there.

Pretty great place. Love the outdoor areas. My only complaint is that adults who are not partaking in activities still have to pay the whole day all activity fee if they are only there to supervise their children. Sucks that we cant just be given a non-participant bracelet or something.

Lots of stuff to do here; climbing, ride the ziplines, hike, mountain bike, do the 200 step incline, swim, bounce on the trampoline, indoor soccer (there is 2 indoor fields) also go to concerts at the amphitheater. Great place and has a great playground for the lil ones

Love this place. Perfect for family walks, hiking, mountain biking, or just hanging out in a beautiful area.

We take our 2 yo daughter for soccer buddies every Saturday. Its a big indoor soccer area divided into 4 sections for different ages. The coaches are great.

Absolutely love this place! I wish it was closer because Id take my kid more often.

This is a nice place to take your family and let them play and swim and have slide nice place

Nice installation. Front desk employees are very nice too

First class all the way! Huge! Something for everyone. Dont forget to bring your dog too.

Kids are little stuck up rats that the staff doesnt handle

Love this place! Visit three or four times a week. Tons of trails and the stairs are always a challenge!! Would recommend visiting!

Fun things to do inside and outside. The pool temperature is great for the kids and the slide provided endless hours of fun. Trampoline park was also fun. You can go outside and play for a while. Places to walk or hike. Nice playground equipment for kids all ages. They also have soccer fields and great picnic areas. You could literally stay here all day.

Really nice! Would go again. Big Fields, nice picnic areas, huge trampoline, nice playgrounds, and climbing courses.

I love MAC so much. I have been going since it first opened. I go to the MAC about once a week with friends from school. I would definitely recommend it to teenagers because it is a place where kids can hang for multiple hours at a time! one my favorite places to go to in Castle Rock.

LOVE all the different activities at The MAC and the fact they KEEP adding more and more, the pricing is fair and the bathrooms are clean, funny smell in the vestibule when you walk in, but that’s been that way for years. Can’t wait to see what they bring.

This is an amazing facility but VERY POORLY MANAGED. I have never been treated so disrespectfully or rudely by a manager as I was at the MAC. I was able to get beyond their policy of charging all spectators the same price as participants. However, after some confusion at check and upon sharing my situation with the front manager, Rebeca, hoping for some empathy and collaboration to reach a mutual solution the manager rather put her nose in the air, said nope, turned on her heels and walked away from me!!! Case closed, end of conversation!! She displayed a complete lack of people skills, leadership skills, management skills, respect, and basic kindness. I literally have never been treated so poorly by a manager and after speaking with local residents the staff at the MAC as a history of rude and incompetent management. Not only do I hope to empower future visitors with my post to prevent this abuse and disrespect in the future but I also hope my post spurs change in the management staff and policies.

Great complex with lots of activities for the entire family. A great asset for Castle Rock.

This is a pretty awesome place and the kids absolutely loved it.

My husband and I just tried to take our 3 year old there to play. It was going to cost $31 for her to play on the climbing structure and jump on the trampoline because we needed to pay for ourselves as well. They charge parents to watch their own children?! We’re at jump street now and we only spent $5.99.MACs pricing is absolutely ridiculous. I couldn’t imagine bringing my other 2 children there as well. Such a rip off. Never going back.

Fun place to throw a party!

What a rip off! This place charged me $45 for my two kids to play on the trampolines and the indoor play set. Wow!! Totally not worth it. Save your money and go elsewhere. Even the front desk people agreed it was insanely expensive. But upper management doesn’t care, they said.

When an employee makes fun of a child..... I can’t find any words to explain how devastated I feel for my son. I want someone from this location to contact me ASAP.

Honestly, this place is great but the prices are way too high. I am so disappointed that they make parents PAY in order for their children to play at the indoor play structure. The parents should never have to pay to take their children to a play structure that the parents are not even playing in (and having a parent playing in the play structure would probably not even be looked highly upon anyway). This parent pay rule REALLY needs to be changed. It really seems to frustrate a lot of people...

Very nice facilities and playground. The adventure park stuff looks really cool but is pretty expensive. ($60 per person to do the epic obstacle park.. $89 per for ziplining...ouch) We will be back for that though!

Its a great place to take the kids when youre looking for something to do. Between the on the floor video game the three-story jungle gym and the swimming pool this place offers everything that your child might want. The swimming facility is good not great. I find it for really young kids there needs to be a few more options. For the middle age kid the whirlpool and the basketball hoop in the water slide is awesome. The three-story jungle gym is awesome there arent many things within a 50-mile radius that can compare to what this place offers. In short its worth getting a punch card and going there for 3 to 4 hours every weekend.

Really enjoyable activity center for kids under 14. 3 indoor fields, a trampoline section but costs 7 dollars extra, indoor jungle gym, and swimming pool. Could easily spend 2 hours here. Biggest complaint is that the swimming lessons take over half the pool including the slide and the fields are available only if another class or organization has not claimed them first.

We used the small pavillion areas next to the soccer fields. The area was clean and in great condition! This entire complex is family friendly, except the parking is so far away! Im using the accessible parking right now due to surgery, and I found it a very long walk!

Lots of fun stuff to do.

This place is fantastic! Theres lots to do, even though the pool is small. The water slide is lots of fun, as well as there being a basketball hoop and a kids play area including a small slide. I recommend this over the Rec Center if you want to have more fun and less people.

Came here for the first time for my nephews birthday party. They were all round 6-10 years old and had a blast on the trampoline park and the pool

Pleasant faclity i didnt like that you had to pay to watch your kids swim

This review is only the rec center, not the outside part. They have a decent pool for the kids and a mini trampoline zone which the kids love. However, the prices for entry are really high. Im charged the same fee to walk in and watch my kids as I would if doing the activities. Which brings me to that. This could be a great facility, but it has nothing for adults. No gym, no track, no exercise classes. Why would I come here regularly and do nothing? No thanks.

Great place for family fun! And very reasonable prices for birthday parties, etc.... My kids love coming here on the weekends. You can get a full day pass and spend all day there. With swimming, trampolines, jungle gym and sport courts theres tons to choose from, but pack a picnic... Outside of getting a pizza delivered there you wont find food close :(

So much to do. Loving this park!

:) Amazing microcosmos of life in Colorado !!

Fabulous swimming pool. Lovely atmosphere for kids and parents.

I will never again waste my money here. The staff is incredibly rude, unprofessional and condescending. Its an absolute shock to me that the young girl at the front desk hasnt been fired yet. There seems to be absolutely no rules, no consequences and no supervision. If you voice any concerns of bullying, violence or nefarious behavior absolutely nothing is done. If you have smaller children, dont let them out of your sight, or please just dont bring them here. Wish I could give it 0 stars.

This place is a joke!!! The price went from $7.00 to $15.00 per person, in one year- there is not that much included in that price! So much for Castle Rock having a fun place for kids... once again it’s ALL about the money! Complete rip off, take your kids elsewhere it is NOT worth it!

Such a great place for family activities! Beautiful scenery and so much to do!

We went for swimming. It is a wonderful swimming area...however, I would suggest having more than one lifeguard on duty. I was also disappointed in the fact that I could not ride the waterslide with my son (each other rec center we have been to (namely, Wheat Ridge, Golden, Highlands Ranch) allows me to either ride with him or stand at the bottom in case he has any problems. He is working on his swimming and is the right height for the pool here....they just wouldnt let us enjoy the slide too (even though I saw a girl and her mother going down the slide together--guess I should have asked for forgiveness instead of permission!!!).

Nice find for parents who need any weather activity. Charge $7 additional fee to access the trampoline area which is in addition to the rest of the place. Staff friendly, place is clean. Very fun for the kids but young kids can get knocked over by older kids racing in the play structure. Pool is perfect for toddlers, family changing room is huge and clean. Would like to see more snack options apart from vending machines.

What used to cost $7 to use the trampoline park now cost $15. This price jump literally happened overnight sometime in last couple months. Today I was also charged an extra $7 to wait for my son in the waiting area while he jumped. For my son and his friend and for my self to wait it was a total of $37. Im guessing this was our last visit. Not sure yet if they will charge me to leave, still here.

If only you could rate the outside separate from the inside. The outside is amazing, the inside is a robbery; specifically the trampolines.Let me back up. It’s not about the money...but trampolines are a separate charge in addition to the entry fee. Because my son is 6 not 7, they charge you as an adult to jump with them. Already this feels like theft, but it gets worse. I also bring my 18mo daughter. She cannot jump on land, yet alone trampolines. However I am required to pay another 7 dollars because she cannot sit on the carpet and watch. She has to be on the trampolines with us. About three minutes into my son and I jumping, we were asked to leave because my daughter was spending too much time sitting. It’s a trampoline, she cannot jump, she’s a toddler and falls a lot, yes she’s on her butt a lot; what is wrong with this place!!??Just to recap. For the three of us it is $18 to get in the door. Add another $21 to get on the trampolines, only to have my toddler spend too much time on her butt, and be asked to get off the trampolines.You should hear their excuses; it’s city laws, it’s our liability. Really, let me sign a waiver...how can airlines let toddlers under two fly for free.Immoral policies that are not family friendly.

This place is awesome! My kids love coming here. They can play, swim, jump, run, anything for hours. And the people are so nice. This place is all about the family!

Great place for the kids to burn off all that energy!

Such a beautiful park. We love the hiking trails and the new aerial park. The Zipline is fun. My son lives the splash park. We utilize the amenities inside as well. The swim lessons are wonderful and of course e love that Soccer Buddies is so close to us now.

It was great for the most part but if you dont like chlorine then you should stay away from the pool because the amount of chlorine that put in there is unbearable. The trampolines dont break. The worst thing is that there are a lot of entitled parents.

Our granddaughter is in all day camp and loves it.

Lots of daylighting in the pool area. Great swim instructors for kids. Smaller class sizes help too. We havent done any memberships yet, so I am not too sure on the price to benefits.Lots of fun stuff outside the complex too.Its just about the right volume of people too... not too crowded yet.

The facility is great, Unfortunately the staff is horrible and the fee’s are ridiculous, so I’m giving it one star. They charge for baby’s to play in a small area and charge the parents for sitting in that area with their baby. I was floored that they thought it was ok to charge me $5/$6 to sit while my baby plays in a 6x6 area. I can understand if I wanted to use their pool or anything else, but we were just going to wait while the older kids play. I’m not paying to sit.

Great place to take the kids on a rainy day! Actually, given the incredible playground, on ANY day! Super affordable, and offers lots of activities for the kids (and adults!), including trampolines, the indoor soft structure playground (similar to Monkey Bizness), and the playing fields. Easy to get to, and love that its also located next to many trails!

I love just getting to spend time with multiple of my friends! The price is great and the pool is filled with fun and joy! I love getting to go on the tramps, pool, and the soccer field! I would absolutely recommend this place!!!

A kid brought a potato onto the structure, and chucked it at me. hate this place so i give it 5 stars

Chaos in a big building but a great family rec center.

Nice community center. Pool, water slide, large play structure, 16 trampolines, indoor multipurpose field, batting cages and a golf simulator. Just wish they had an exercise/weight room. But my kids love going there!

This activity​ center has it all! There is a giant trampoline area that always has a staff member overseeing the area. There is a huge gym for soccer/basketball/volleyball/etc. The indoor playground perfect for winter days with kids (probably ideal for ages 0-10). The locker rooms were clean and tidy. The outdoor play area is something Ive never seen before-- ziplines, slides built into the hill, play equipment that is new and fun, sand box area, etc. I havent used it yet, but the pool looked fun and clean.

We had an absolutely terrible experience at the Miller Activety Complex and will not be ever going back. It’s truly a shame as we have had my daughters birthday party there for the past 4 years. Never again. We were in the trampoline area and the girls were flipping and there teenagers thought it would be fun to jump on their trampoline while they were flipping. We brought it to the attention of the boy working there and he was extremely rude. We could tell he was friends with the boys that were doing this. We were extremely concerned for the safety of all the girls at the party. I then went to the front desk and the party planner came down with his manager. He was extremely rude to both his boss and the party planner. His boss told us to come get him should it happen again, which of course it did immediately. At this point I was really upset and he had the nerve to tell us that his friends can jump anywhere. I told him this is an extremely bad safety issue for everyone jumping. He then proceeds to tell me that he has the authority and he can have us kicked out. I was furious and went and got his boss again and the manager which he proceeded to again treat them or is with any respect. I’ve never seen anything like it and how a child like that can maintain a job with how he treated everyone. I would have fired him immediately had he been one of my employees. They removed him and had him go to another area and told the teenagers that were causing the issue to stay at the back of the trampoline park and we could have the front. At this point we only had like 10 minutes left. Every girl at my child’s party was scared. They saw an extremely unprofessional teenager show so much disrespect to anyone in authority. I would be ashamed if he was my child. Unfortunately this terrible experience will affect several girls lives and my daughter will forever remember her birthday negatively. On the positive side I hope these girls learned it’s ok to stand up when someone is doing something inappropriate and to fight to make the situation right. This wasn’t handled properly on so many levels and we will never go back. Giving us a coupon to come back for free by the end of 2018. Not gonna happen and won’t make any of this better. What a joke! Please be warned that no one knows how to keep your children safe in the trampoline area. I’m shocked they haven’t been sued!

We love this complex. All the amenities are amazing! I climb the stairs and run the trails almost everyday. My son loves Soccer Buddies. We spent a lot of time at the splash park this summer. In the winter we hit the pool. The park is so fun for the kids. I loved the zipline and the music at the amphitheatre. Im looking forward to trying the aerial park.

Wonderful facilities! My kids could have played there all day. The pool is wonderful and the indoor play area was equally amazing!

We just stayed outside and “played”. Nature mixed with fun, full-bodied outdoor play equipment at it’s best. Picinic tables, port-a-pots, treed ares, soccer fields, fire pit areas, trails. Manageable for little children yet fun enough and interesting enough to captivate teen-agers and adults!

A really nice outdoor facility built in the middle of a plot on land that would otherwise serve very little purpose. Take the 200 steps challenge, or test your Am Ninja Warrior skill.

I have only ever had great experiences here. Until today. If i could rate the indoor and outdoor facility seperately, the outdoor facilities would get 5 stars. The ropes course is amazing and they have the friendliest staff. The indoor however is a very different story. The ladies at the front desk are extremely rude and disrespectful. They dont talk to you, they talk down at you. They are snotty and entitled. This is the worst customer experience I have ever received. I will not ever give the Mac center my money. If I am going to take the kids to the pool, we will be going to the rec center. They know how to treat people with respect.

Over priced. Kids like it. You need to be there for several hours so you get your moneys worth.

Awesome place for a workout and any other type of exercise a person can want.

Great place for all ages!!

First time I ever went was awesome! Cant wait to go back! Even fun for the adults.

I went to the place to a moments relax by myself sitting aside, the stuff including the front desk manager are horrible and being rude to me and called me stupid. I have many years working in customer service, their unprofessionalism absolutely ridiculous. I will never use their service specially the paid ones. I think they should be ungo some professional and curtesy customer service training. Please make your guests feel welcomed and liked but not being unfriendly frequently.

Wonderful place for the family!! We drive up from pueblo, my sister in law lives in castle rock and we love gathering for special events here. Definitely an aaaaahmazing experience for all ages!!

Came here for the Halloween event my son loved it. I really wish we found this place sooner since we are moving soon.

Fantastic! Tons of activities for kids and a great price! Most of the outdoor activities are free and the indoor stuff is very reasonably priced.

Fun and inexpensive. Super clean pool and facilities. Family changing room and lockers.

Fun events. Good time.

The outside is wonderful. It too bad it la associated with the inside. Be aware everything else is a fee. Trampolines are $7 to jump, and if your kid is under 5 they charge an addition $7 for you to jump with them; their rule. There are really no other facilities on the inside unless you play soccer. We have a six month membership that we will not renew. Though when we signed up they said our nanny could bring the children; now they say they cannot. In general customer service is quite rude and unhelpful. Unless you come more then twice a week, it’s cheaper to get a punch card.

Staff is rude and shows lack of regard for concern especially when it comes to supervising the kids jungle gym. Older kids were vulgar, playing rough, blocking access to parts of the gym, with no regard for smaller children around them.

The Miller Activity Complex is a great place to have easy fun! The cost to be able to enjoy their several activities, which inculde a nice synthetic turf soccer field, trampoline park, kiddy jungle gym and several other things, is fairly priced and not too expensive. If youre looking to have a party, they offer some options with one of those offering the ability to rent out the entire complex. I did this for a large church group party and we had a blast! Parking is easy, the location of the building isnt too difficult to find and I have experienced great customer service. I highly recommend this place for a fun activity that is family friendly and enjoyable or sport pick up games.

I love this place and spend a large part of my time there while my kids have tons of fun. During the warmer months we spend almost every day there and often times dont leave until its dark. We park a cooler of food, and plan to spend the day there. Its noce because I can get stuff done at picnic tables, while watching them playing and having lots of fun.

Fantastic for soccer, swim lessons, hikes, picnics and so much more. Lucky to have this in Castle Rock.

I love the Mac. It is great for kids and anybody looking for a good day of fun. You could go Ziplineing or become a ninja on the obstacle course. You can jump on the trampolines of play on the playgrounds. It is a great day of fun and I would suggest going strongly. . . . . . . . ................................................................................................................................................................................................ ..........

Amazing outdoor space and great trampolines, the is an OK pool but a small one, but fun slide and awesome play park and turf fields, I really recommend coming and enjoying a nice day.

Great place for kids

Birthday party last night and I was blown away by this complex. I didnt have time to check the inside complex but the whole beautiful area for the zip line, 200 wooden stairs to the sky, all the activities in this area is something I couldnt imagine.Little children, teens, adults and even old ladies like me just enjoyed the views.Just Google MAC, Castle Rock to get all the information , its new so need to get the word out.

Ridiculous. $15 for my son to use play on their trampolines AND I have to pay so I can stand and watch Theres better kids places in Parker.
