Beautiful, mostly open terrain that leads from the trailhead under Hwy 93 to the west. Very gentle incline but its a long series of trails. Even connects with doudy draw trails

An extremely fun green level trail.If you try to park at the trail head Google Maps directs you to for Doudy Draw, its extremely limited.Pro tip: if coming from Boulder, instead of turning right at the light with the gas station, turn left and park at the larger parking area at the bottom of the trail head. There were ample places to be park even at 08:30am on a Saturday.Parking in the larger lot will require you to ride a solid 900ft climb to earn your turns. Once at the top, the trail is a nice loop with an invigorating downhill run.Expect to encounter lots of rocks (mind your pedal position) and sections at the top do have some trees to weave through.If youre getting back in the saddle after some time off or want to enjoy a fun green trail to hone some skills, look no further!

Basic simple trail system. Good for some cardio. Mixed single track and double wide gravel.

One of my favorite Boulder trails. Excellent any time of the day but the evenings are particularly beautiful with the sunsets. Great place to go mountain-biking as well, nothing too difficult and a lot of fun

Nice, short, little dusty, free parking across the street.

Ample parking in two lots, provided you arrive early. Gas station near by for restrooms. Good signage and maps at trailhead.

Good trail on a cold but sunny day. Lots of sunshine

Absolutely beautiful. Di not travel all the way up to the campground. Its small and there is no creek. Theres a nice place to stop just as you start going up and it says something about the road is not maintained. Its on the left and there are places to put your chairs right next to the creek. Read a book relax or do what my family did, sleep.

Amazing views of Boulder and the flatirons. Always love to hike and bike here. The biking is not the toughest around but lots of choices for trail paths. Look out for mud closures as Boulder preserves the trails when they are too wet to hike or bike.

Ended up at Marshall Mesa as the parking lots for Homestead and Doudy Draw were completely full. Beautiful easy hike.

Marshall mesa is a good park, close to Boulder. The trails arent super technical or anything, but still good & fun. No prob on a hardtail mountain bike. Could do the rocky sections on a CX or gravel bike too. No E bikes.

Great ride! It does get crowded. But that feels typical of Boulder.

Awesome trail. Dogs may be off leash if they have the Boulder voice and sight tag

Beautiful area. First time there.and the views were amazing.

Some of the best running trails around Boulder. The perfect 15 mile loop. This trail is often closed for mud in winter and spring. The mud is no joke. Heed closures.

A great trail for an easy hike or families. Beautiful views of the flat irons. The start of the trail is walking or biking so there is a lot of sharing the trail but then it separates. This space has limited trees, so in the sun it can get very hot with little relief.

This trail is very nice very early in the morning for a trail walker. After 8am, there is an influx of trail runners and mountain bikers all over. Expect to move out of the way often if you decide to go when everyone else does. Lots of dogs off leash as well. Mind your pups out there.

Bring cash if you plan to park here and don’t live in Boulder... great spot to park for riding mountain bikes with a gas station and snacks across the street.

Fun ride. Different trailheads all over park area. 14.5 miles total round-trip. Really a good ride for all types mountain biking. Endurance training.

One of my favorite places, scenic overlooks of the flatirons and sometimes you will see see amazing wildlife

Fantastic trail for running, walking, and mountain biking. Over 15 miles of trails with beautiful views.

Beautiful, peaceful, reenergizing.I have not done the full trail loop but there are cool hills and big rocks that bikers have gone through. Dogs can be off the leash if theyre responsive and there is a cool cattle area at the base of the valley. The wild flowers are vibrant and friendly. It is wonderful to stop for the sight or a picnic or to enjoy the flatirons and hike.Highly recommended trailhead.

Non boulder residents pay a 5 dollar per day fee. Best 5 dollars ever spent!

Early in a weekday the trails are open with only a few people passing on foot or bike. Flowers are starting to bloom and lots of birds out! Very beautiful and well marked trails.

Nice trails but it is very exposed. Not a great hike for hot sunny days. Otherwise it was awesome.

Beautiful trail and surrounding area. Plenty of parking. Lots of people out riding the trail on their bicycles.

Beautiful Mesa. Nice hiking and mt biking.

Easy riding, mainly groomed trails, with beautiful backdrops of the mountains. Some portions are a bit steeper than others but theres also loads of flatter trails.

Always great and everybody knows it...

Great place for a leisurely stroll! But a lot of sun exposure.

Love this area very beautiful!

Free parking for Boulder County residents. Minutes from the City but a world away with crystal clear water, picnic area and gorgeous easy hiking. Vistas are inspirational.

Great spot just south of Boulder and close to Eldorado Canyon

Awesome trail. Very exposed and can get busy with hikers and mountain biking but its for a reason. Watch out for snakes mid day.

Best Mtb bike trail combined with Flatiron Vista, Spring Brook loop and Dowdy

Popular trailhead on the southern end of Boulder. Nice 3 mile loop with great vistas of the Flatirons - although not much shade by extension. Bathrooms and plenty of overflow parking across the road. Also has trail access down south to Flatirons Vista and east to Superior / 36 bike path

A 3 mile hike with great views. Lots of bikes and dogs on weekends.

One of my favorites for a quick walk with the dog. Very popular mountain biking and running trail too. Pay to park or park across street in dirt lit for free!

Busy trailhead in south Boulder. There are two different parking lots. One is a fee lot. Great flowy riding or mellow hiking along the trails from this trailhead. You hsve the ability to connect up to a multitude of trails from here.

There were only a few people. Air there is amazing. There are a lot of pine trees. Dont forget to wear waterproof boots and hoodies. It is safe and good work out.

Awesome area that is kid friendly but not for taking strollers. Bike, run, hike. Its all good here.

One of my favorite easy access trails with a fantastic view of the Flatiron mountains. It is around a 3 mile loop, but it connects to various other trails to make a much longer loop. Great for beginners.

Its really like, outdoorsy. So fun

Marshall Mesa is a fun trail system with fun things for bikers of all skill levels, runners, and hikers. It is very well marked with lots of maps and signage. Marshall Mesa connects well to Dowdy Draw and other trail systems around the area. With beautiful views of Eldorado Canyon it is a great place to get some exercise and fresh air!

Great place for a sunrise run! The views are beautiful. Got up close and personal with a a big Elk buck. What a way to start the day!

Fun trail. Rode the trails to Superior.

My first real ride and I loved it

Ample parking with a bathroom at the trailhead. Nice informational signs around and a great flat-ish trail in South Boulder with great views.Bring a hat and sunglasses because there is no redemption from the sun on most days. Oh yea, and watch out for snakes- they arent uncommon there.

Great hiking trails. Not very crowded on weekdays. I just wish people would not leave bags of dog excrement along the side of the trail.

Great multi-use trail. Friendly people.

This is a great trail system for beginner mountain biking and also for relatively flat trail running. There is paid parking or free parking across the street. There is also bathrooms at the trail head. All of the routes were well marked.

Lovely in late autumn...can’t wait to see it in the late spring.

Great trails.

Easy trails with lots of connections to easy Boulder county and the Elorado canyon trails. Views are nice too.

Used to ride this a lot. This is a total beginner place. Not that great if youre experienced but still rip-able. Not much climbs which makes it great for anyone trying to get into mountain biking or trail running. Very good views from the south Boulder region.

Nice view along the way to this trail. But it closed when I arrived. Check the website before you go.

Amazing biking area

Relatively flat area to hike / bike, be sure to wear sunscreen as there is little shade

Best trail system in South Boulder. Closes often during wet/mud conditions. Bathrooms and plenty of parking.

This place is awesome. Its right across from my grandparents house. We constantly see bikers, horseback riders and people hiking up the path.

Great trail for getting some miles in. We mountain biked there and it’s a fast flowy open trail with great views.

Well maintained, but muddy from a recent rain. Lots of diverse flowers and vegetation. We saw a bull elk! Good parking area.

Nice riding but wish they had a one way loop. The crowds dissipate on weekdays nicely.

Great mountain biking trails!

Nice place to ride bikes and hike ... Overlooking a beautiful lake with a view of the flatirons.

Lots of flowers in mid August when I visited. Nice open space with not much incline.

Great place to walk and bike. And an amazing place to watch the sun set over the front range.

Wonderful trail, great geology. Dont try and map it though

Great flavor salsa, food is simple and lots of flavor. Best salsa in the area by far!

Is fine if you are from Boulder. Costs $$ to park there if not. Park across the road where its free.

Beautiful! Nice wide trail. A lot of people use the trail to train or to walk with their dogs. Easy access to other trails on the mountain.

Adequate permit & paid parking at this easy to access trailhead. There are a couple vault toilets when needed. The mixed use trails provide as much or as little effort depending on your mood and ambition.

It was a nice trail, however the mountain bikers were not the most polite cyclists. Would go back, but on a weekday.

Easy mountain biking close enough to ride to from downtown

Excellent for easy to moderate hiking and mountain biking

Nice trail my dog had a great time and it wasnt super crowded

Its an easy 2.5 mike loop hike with amazing views of the Foothills and front range. Also great for mountain bikers. And you can walk or ride a lot further if you decide to do more than the loop--going East towards Superior or South towards Hwy 128.

Great network of trails, for hiking biking or horseback riding

Met a friend here to ride a few trails. Some of the trails run through cow pastures, so expect some dirty shoes / tires. This trailhead gives access to several different loops of varying difficulty and length. The higher elevation trails offer a few nice downhill runs over light chunk but with solid flow. Better on the weekdays because theres much less foot traffic. Also an ideal place for trail runners.

This is a great trail for taking a loop.

Marshall Mesa is beautiful, usually some cows so I would your dogs if theyre inclined to chase. But otherwise its quiet, the creek that runs through the top is gorgeous. You can cycle there as well.

Great bike ride! Well visit again!

Good access to a few good trails. Nice winter option. Trails close often in the spring due to muddy conditions so check status with Boulder open space. Bathrooms are available if needed, but not recommended.

Great trail, trail head has bathrooms and picnic tables.

Its a gorgeous hike!

Really nice views & trails, can be a little challenging for hikers/bikers to share the trail

Great place to hike

Great beginner mountain bike trail!!

Very easy to get to. Plenty of parking and public restroom. Pretty steep incline to make it to the top

Trail for hike and biking definitely worth it

Hiked this last night May 09, 2016. Marshall Valley trail, Marshall Mesa trail, and Coal Seam trail create a nice 2.4 mile loop... Great for families with small kids to advance with minimal elevation gain and some rocky terrain. Near the end of the trail we saw a deer and the views were amazing at the top. A little muddy in some spots which the kids loved... At the top on the non bike trail, there is a nice flat spot great for snacks and a rest break. A plus.... The short cut loop on the map 0.7 of a mile (Marshall Mesa trail) going clock wise is a non bike trail and allows for a nice climb to the top with out worrying about bikes. This is a nice after dinner hike for sure, will visit again.

Relatively easy mountain biking and hiking trail with several options.

Great fast MTB trail system, also a great road ride meeting place.

Great trails for mounting biking

Great place to hike and bike

Great trail running loops

I love mtn biking here and trail running. A lot of cyclists Marshall mesa because its not very technical, but I love linking up these fast smooth trails when i have an hour before or after work

Right in the middle of everything yet feels removed from the city.

This is a nice, short-ish, very easy trail. Great for walking or mountain biking and with good views of the flatirons. The trails follow a small creek and are mostly flat. More of a walk than a hike.

A bit muddy but the trail was awesome
