The wave pool is broken, so no waves, the hot tub was out of service and was empty, and the kid pool was pretty cold. Dont worry, they still charge full price even though half of the attractions are broken. I thought they closed down to fix these issues, but apparently not.

Great place to take the family all year round. There are 2 big slides for those seeking a bit of a thrill ride and a play structure for the smaller crowd or those just looking for more laid back fun. Dont forget the lily pads, wave pool and sport pool with volleyball net and basketball hoop. If you plan on staying all day they have concessions on-site also and are reasonably priced.

No place to sit down and Im a amputee.But the kids enjoyed it

Amazing place we had so much fun!! Lots to do.

This is a fun water slide place absolutely fun time just to take kids and have fun with them would recommend this place.

Love this place my kids always have a blast never any issues with staffing water is great facility is super clean handicap accessible with bathroom/shower also pool and spa have handicap lift :)

I called a few days ago asking bout what they are doing as far a COVID-19 precautions and such and the lady on the phone was very kind and patient and answered all my questions...even found out Black Friday is the best day to buy a yearly pass as it’s a lot cheaper!

We always have lots of fun here with the children. They really love it.

It was a very nice place to have a small Birthday Party

Haven’t been in a while but I remember thinking it was Overpriced for what it was.I think we will wait and see if the reviews get a little better since it reopened since u know it’s the only indoor water park here.. so dissatisfied with the options of entertainment here

Its fabulous..go have fun

Ran very well! Had a great time

Prices are a little high but my kids always love it here. I did have an incident where my child needed help in the wave pool but the life guard said it was MY JOB to get in the water and help her? Other than that it is fine.

My boys loved it there!

This place was so kid friendly, and the employees were wonderful. As an uptight anxious mom of one, I did not feel the need to be a helicopter parent. This is a great feeling

This was my first time here. My kids, husband and I had a great, fun time. The family bathroom wasnt quite as clean as I would have preferred but the main restroom was acceptable. I thought the price was a little high for what they have available regarding attractions.(The following is more a reflection of patrons rather than the reef). I think it would be nice if parents were a little more attentive of their children and their behavior as there were some kids that were skipping and weaseling in front of smaller kids in line as well as climbing slides when others were waiting to go down and even piling up and not waiting for kids to get down the slide before going.

Had a great time with my 3 children - 9, 6 & 20 months old. I would suggest this park is suited to kids up to around 12 years old, so was absolutely perfect for us.The 20 month old had a particularly fun time in the children’s water playhouse.Great that it’s connected to the hotel too.

Cant wait to see what they do after they get it fixed. Its a bummer about the flood. But they are not letting it get the best of them. Hold your head up and strive to make things awesome again.

They should charge full price if the hot tub is unavailable

Fun place to go in winter months for slides and swimming. Our son loved it.

Wow! This place was so much fun! We took our nieces and nephew here, but even without them it would have been so fun! The water slides are really fun and exciting and the lines are short so you are constantly having fun! Even my 1 year old nephew had a great time in the kids zone!Its a great place to bring the kids!

Second time taking my family here, it’s great. My sons love it. They are 6, 3, and 1. It’s perfect for all ages, the only downside is we were there for 4 hours and the wave pool was NEVER on. And we were in it for at least 45 minutes waiting.

I love the reef I am 11 and Im going for my birthday every year I just cant wait to see it I bend to the reef like my be 11 or 12 times its the best thing ever who mad the reef are the best people ever and the people working there are the best to and ya I just the reef well buy Im at the reef see ya

The biggest draw of the Reef (and a brilliant business idea) is that it is an indoor water park that can still be in operation during the winter months. With that in mind this is a GREAT place to get a season pass during the winter months. Everyone gets to pretend like it is summer for a few hours a week and then go sit in the hot tub. It has been a God send for my family this winter. The staff is great, there is a enough for the kids to do each week to keep it fresh and fun. My only complaint is that there is water all over the bathroom floors which makes it hard to change and not get your dry clothes wet. I dont know any way around that, but that would be the only thing I think they can improve upon!

Great fun for the kids!!

Pretty cool staff was nice water was clean

Always lots of fun. Wish the family locker room had more stalls. We had to wait a long time to change. I also wish they had gluten free options to eat there

Not what it used to be. We used to have a family pass here but ended up moving away. Back in town visiting we decided to go to the reef. They used to have life jackets for kids now they charge for them to rent, seems like a bad idea. They used to have stacks ofFloat tubes but now there were only 4 to share. The wave pool was not working , it was sad. The life guard was not watching the pool at all and could not even get their attention, good thing no one was drowning. Warning, they charge more on Thursday than the weekend, no idea why but it was almost 60.00 for 4 of us. They said it would be cheaper on the weekend. On the positive the pool was nicely heated. I hope they get everything repaired, get better life guards and please buy a few more float tubes.

Giving it a 4 because it was pretty darn cold and they lack a kid pool. Yes they have a splash pad but would love a shallow pool for the toddlers.

Been here several times. Each time its a little more run down. Parts of the kids park do not work. The hot tub is just that. None of the jets work. Wave pool has a load buzzer that reminds you how disappointing the place really is because the wave pool has no waves. And now for the slides. The orange one you can feel every section scrape your back the entire length of the slide. Purple one is great. If you wanna wait for one of the five a deflated tubes. Sad to see these types of places go to waste.

Stayed at the hotel next to water park thinking they were connected. They werent but we got a discounted price of 10 bucks per person. It had two water slides. One you went down with an inner tube, the other on your back. The slide on your back hurt because of the jolts. My back was red for hours after and hurt. Also, the wave pool didnt work or wasnt running. It would have been nice to have a regular pool. Kids were able to spit going up the stairs because there were spit piles all over. Was very dirty.

Fun place to visit especially in the winter.

I took my grandson there. It was very popular for pre teens.

I absolutely love bringing my daughter here we stay for hours the only problem I have is this....either do an expansion on the sitting/public area or have more private rooms for birthday parties. I am at this establishment as I type this and I’m sitting in the lobby area as there are at least 3 different bday parties in the swim area and each party is using at least 3 tables and 15 chairs!

It was a wonderful day. The kids loved it and so did I.

My family had a blast. Smaller park but it is indoors. Had things for our 2 year old to our 13 year old.

If I could rate this 0 stars I would. Some kid had a nail go through his foot. I never want to go here again until they do some serious remodeling and cleaning

It was fun

I love taking the kids here. I would recommend that they put the bar back in the area to where we can watch your kids so were not sneaking off down to the Hotel bar.

Super fun for all ages! Even a hot tub for when we were ready to take it easy for a bit. :) If you arent staying in a room though, remember to bring a towel!! I also wish there were changing rooms. (open area for changing, or small bathroom stall with no shelf)

Its a lot of fun the kids are having a blast Im happy with the water slides for kids

Kids love the activities and I like the attentive staff

While the atmosphere is great, they serve food and the littles can enjoy the splash park and little slides, the water temperature for the smaller children in that area is FREEZING. Im talking even my husband and I were shivering after going down the small slide there with our son.Warming it up should be a priority for little bodies, especially in the wintertime. They expel heat WAY faster than an adult does. A small child doesnt want to sit in the warmer wave pool either, or ours doesnt as theres nothing in there to play on.We werent allowed to sit with our small children and take them down the large slides with us, which was disappointing. They ALL wanted to go, and ranged from ages 4 to 6.Get the water temp fixed for the smaller children and more people would come back on a regular basis! Otherwise its a fun place to spend the weekend with your kids!

The water in the wave pool was SO WARM. My kids had a lot of fun here. I liked that it was was big enough to have fun in but not so big that you can loose your kids. Will definitely be going back.

Family Fun for 12 years old and younger. Great once or twice a year, but not enough variety for repeated visits.

Clean environment good price in a awesome place to swim. Its a getaway away from home

Kids love it. Definitely a family friendly place.

Needs more slides to ride

My daughter always have fun when we come to the reef

Great place to have in Billings. Not sure if I’m just a whiner or if anyone else thought it was just a tad cold in there to be completely enjoyable?

Totally great if you have kids, maybe not so much of you dont. I wish I was a kid again with all the cool stuff here. When we went, the wave pool was not functioning, which apparently happens a lot, based on what I have heard.

I loved the reef! It was so much fun! I just love going there!!! I would call it a 5 star rating but, the prices are a little too high. At the Oasis in the heights is way cheaper. But there pool isnt very deep like at the reef so the reef is kind of better. But I hope everyone get the chance to visit the Reef. :-)

Kids had fun but guests should get more of a discount.

Really fun but the floor is rough and hurts my feet

Something is always broken, not taking very good care of. Last time we where there the safety nets around the toddler area where torn alowing the kids to get under the slides and platforms, many of the water features on the platforms didnt work, most of the life guards where more busy with socializing with each other them with doing their job (not all but most), the hot tub was still broken, my daughter [3] had fun but diffently not worth the price

Had a blast cant wait to go back

We rented a hotel room thinking that they would get to play at the Reef for free, but then they tell us that we still have to pay for the water park and would get a discount. We decided that the kids would be disappointed if we didn’t let them go since we told them and got them all excited about it. Still had to pay $10 per kid even with the discount which is outrageous and then get in there to find out that the wave pool is not working. Very sad and disappointing for the kids. Definitely not gonna be thinking about coming here again.

I love going on the slide with my 10 year old boy. He and I had a blast!!!

Its expensive! Geared more for 6+ years old. Brought my toddler there. Someone pooed and they shutdown there park and offered no refunds.. was fun while it lasted

This is a great water park that youre able to visit all year round. Overall I feel the prices are decent and comprable with everything else around. It has numerous activities for all ages. It even has slides for kids preschool and younger. There is plenty of space and seating for adults to watch the kids even if you dont wish to participate. Because this is an indoor park expect it to be hot, humid and loud. They have life jackets available if you didnt bring any. There is a concession stand and their Pizza is way better than you would expect.

Air temperature is too cold and frankly the water temp could be increased too. My 3 year old was freezing, lips turning blue and shaking. Took him to the hot tub to warm up to be kicked out, no kids under 6. Returned with my older child to the hot tub to warm up and the employee was very rude (thinking I was with my younger child) and tried kicking us out again. Big difference between 6 and 3 years old. Also no signs posted anywhere stating the 6 year and under werent allowed nor were we told when we paid. I was grossed out with floating hair in hot tub multiple times and a floor. Other pools seemed better. Did not eat there so I cannot say about the food or cost. Felt it was quite expensive for a family of 4 for 2 hrs because my youngest was so cold he just wanted to leave. They need to fix the temperature issues. It would make it a lot more fun for everyone if they are not going to allow smaller kids in the hot tub to warm up. That and keep the hot tub cleaner.

Pretty cool place to bring the kids for the day,and reasonably priced.Drove in from Bozeman.

Great little place. Too much chlorine though

Ive been here twice now and I must say it seems really fun, if youre a child. For the adults, especially those without children, its doesnt have much going for it. For the adults there is a wave pool with very small waves. The waves are small enough that it almost doesnt qualify as a wave pool. Youll get more enjoyment from the two waterslides. But I tired of them fairly quick. And then theres a pretty good sized hot tub. And thats about it for the older people.I didnt have any food, but the group I was with did. From what I heard the food stand was a disorganized mess. They were missing several items and if you wanted pizza you had to order it right when you got there because there was an hour and a half wait. I did see another group eating pizza and it looked pretty lackluster.But really I dont think Im the customer base they are aiming for, and for families it seems like a really fun place to get out of the sometimes nasty Montana weather for a swim.

Love their hotel and water park

Fun indoor water park. A little expensive compared to places weve been in other locations. Regardless we had a great time. Great toddler play area with fun slides, wave pool and monster slides for bigger kids.

I mean, its not bad, but the fact that they advertise a wave pool, and charge full price as if they have one, and then dont announce its broken until you ask when the wave is going to happen all tells me they kinda just dont care.

I plan on having Daughters birthday again there next year it was awesome

Its a little spendy for what it is but the kids love it. Very popular for birthdays but the rooms are not temperature friendly for spectators (VERY HUMID). I have seen the lifeguards in action and they are very responsive. I feel like my children are safe even if Im not with them. Life jackets are also provided but are limited.

It was awesome !!!Except wave pool only goes like 4 inchesAnd the hot tub is just a spa no jetsWater slides are amazing though

There was nothing there that looked that fun they dont even have a tolet water slide and there wave pool was broken abd not working,Another thing that i wanted to go on was a lazie river. Definitely not something i would spend an hour at.

Water was FREEZING, which was unexpected. The jets in the hot tub were broken. The staff was rude and completely over the top. Yelling at kids just having fun.

Pretty fun...when its COLD outside.

I have been here many times. Each time it is getting worse. The life guards are very rude. And are fully clothed.(no Bathing suits) The hotel quality is ok i had very loud neighbors above us.I do NOT recomend.

Great place to throw a birthday party

Whole family got pink eye after the visit.

Was not expecting this extra price for swimming and you have to pay 10 for 1 towel!!!? Thats 50 in towels for my family! Ridiculous but kids have fun otherwise.

No waves in wave poolSlide policy too restrictive for youths :O

My grandkids had a blast. 5 & 1/2 hrs & still wanted to keep playing.

Good water park for little kids. However wave pool is broken and has been for many years. The water slides are fun. And theres good things for a smaller kids as well.

Quite a large indoor water park with plenty of fun.They offer seating near the water to eat the food served there as well.The food court is now owned by a different group who seems to actually care about the quality of the food now.The wave pool is quite a bit of fun!

Had a birthday party here for my son with many family members tagging along. The pools and splash park were really fun for him, and all but one water gun was operating. He wasnt big enough for the big slides, but I sure had fun with them and there wasnt any wait time (around noon). My only beef with the pools is that the smell of chorine was really heavy, but maybe thats expected for an indoor water park build mainly for kids.For a birthday party, I felt like more service couldve been included in the price. We went for a pizza to celebrate, and it was going to be an hour and a half wait for it! Their fryer didnt seem to be working correctly for chicken strips (they came out cold), they pretty much ran out of stock on most food items. We tried their pretzels, and found it strange that they spray them with Pam non-stick spray before handing them to you.All in all, I enjoyed going and my kids all had fun, but itll probably be a while before we head back.

We had a good time playing at this indoor water park. I found it a little odd that the pool temps were so warm while the kids play area was colder. It was also very loud. But these are minor inconveniences. Overall the place is very nice and the kids seem to really like it.

Very nice facility. We went on the YMCA family night, so it was a great deal. The water was really cold on the day we visited. The kids area water was freezing, but the Lily pad area was warm. Other than the water temperature, we liked it!

Wouldnt even give this one star but it wouldnt let me choose none. Terrible experience. Showed up to have a party only to find out we couldnt bring our own food. Then after that they found poop in the wading pool and just grabbed it out and put more chlorine in there. The hot tub was not working it was colder than the other pools and after asking for a pass to the sliders after we had only been there for a few minutes the staff wanted me to pay more for them.

Loved it but dont like the pay to enter it should be free for hotel guests

Took my son there for his birthday, we had fun. Only bummer was they had to close the wave part as soon as we got there.

Over priced, and the wave pool is like a hot tub, too hot to stay in but for like 5 mins. My kids didnt even want to stay in it.Only good thing was really the jungle gym.

Great place for kids. Up to about 8th grade, this park is cool. After that age the slides are not very adventurous. The ability to hang out all day makes the price more reasonable.

Fun place to do some water play, need to stay long time to feel it was worth the price. Little pricey, but kids had a great time.

I love it It was awesome go to that phone

We drove from missoula to billings for a special trip for our son. The main attraction wave pool was/is broken. We were never told by hotel or reef when we called for info. It is a bit old looking, but Was not busy at all. (Wanted more for my son) Was something to do i guess...i think without the wave working, its really only good for the little kiddos.

Lots of fun but kinda pricey.

Coming from the south there are waterparks everywhere. So we were excited about the wave pool here. The complete time no wave pool when lifeguard was asked she said it just wasnt on. Oh well!!!

I do really like this place however, I was disappointed that you now have to rent the life jackets. Last time I brought my kids I was told that they couldnt use their own floaties, so you can imagine my surprise when I was told my only option was a 10 dollar (a piece) rental. You do get 5 dollars back. Also, you have to pay cash for that!

I’ve been here a few times with my young kids and we have always had a ton of fun. The only complaint I have is that they need to find a way to heat up the water in the little kids play area. It’s always freezing and my kids don’t like to play in it because they come out shivering. They stick to the wave pool because it is warmer.

This is a great place for the kids to play - indoors so youre not on the sun with a wave pool, water sides, pool basketball, a younger kid structure that is as good as most outdoor facilities. If grandparents were taking kids on a road trip, itd be an amazing stop!

The water park staff are amazing workers and problem solvers. Granted the wave pool was closed, but the workers, life Guards and water park desk clerks amazing 5stars easy, the hotel staff and such, a 2 maybe. Thank you Reef employees.

Good park reasonably priced with a membership. The one star reviews come from people that are told their babies cant go in the hot tub. Like this is news to some people. The reason why little kids shouldnt go in the hot tub is death. Toddlers die of hyperthermia quickly. Even if they do not die they can suffer irreversible brain damage. So yea it is pretty necessary to keep small children out. Not to mention the sanitary reasons. So dont be fooled by one star reviews this place will always give vouchers if youre Unsatisfied and communicate politely.

Fun
