beautiful hike, but always very crowded. went with a horticulturist and learned a lot about the various medicinal native plants.

Really great views of Boulder. Definitely an asskicker at times, though not always. Trail was in good condition, with lots of people taking advantage of perfect hiking conditions.

The definitive Boulder workout. One of the first to try if you are only here for a short while!

Great trail and beautiful views.

Amazing fog this am with snow flakes. Trails dry with friendly people and amazing views. Happy Thursday m8y's Oiiiii

Lots of steps up (45 min) but worth the reward. Easy hike down.

Great views of Boulder. Decently trafficked by people and easy to find the trail. Around the peak it does get pretty rocky so good shoes and sure footing is highly recommended. Haven’t hiked in awhile and did the loop in a 1 1/2 hours with a longer break at the top.

Gorgeous trail. Strongly disagree with the "hard" rating-- it's difficult for a relatively short period of time, so I think it's more in the moderate category. It was actually rated moderate on alltrails until about a month or two ago.. not sure why it was changed.

This trail is short, energizing and has better views than some of the even harder trails in Boulder.

Gorgeous, nice short walk with some stairs.

If you are going to do this hike as a loop , I would recommend going up Mount Sanitas and returning Sanitas Valley .

Great hike.

Great local hike. Lots of doggos on the trail enjoying the best of life.

Very short but beautiful. It’s pretty easy but there are stairs made of rock. (Rocks are pretty firmly in place) It took us less than 20 minutes including taking pictures.

Fun trail for a quick hike. Clean and not too tough.

This is a great little hike. It’s pretty steep and gets the heart pumping. There are great views of Boulder along the way, and spectacular views from the top. Definitely worth the climb.

Definitely and amazing view once you get to the top. Hiked this trailed multiple times! The trail tends to get extremely muddy and slippery after a snow day, but well worth the challenge!

pretty short, but intense hike going up. cool views of Boulder

Nice trail, not far from homes. Good, steep ascent. Added Red Rocks trail to make for a 4.5 mile hike.

Love this hike. Breathtaking views valley

Very easy walk on either paved or gravel path. Many dogs with most on leashes. Easy to take jogging or all terrain stroller on the path. Several bikers, but most called out that they were coming up behind you. Some good views of the mountains and Flatirons.

very nice trail just very crowded and parking costs 3.00 every two hours or so, starts all uphill then kinda eases towards the end

Not sure if this was a biking or off-road limousine trail, but it wasn't that good for hiking. One trail sign from the parking lot and after a 1.5 mile hike up a gravel/dirt road, the only trails I saw strictly prohibited hiking: bikes only. The Creekside trail half-a-click back down the road is a much better option.

Loved this trail, very rocky and deep going up. I would say it’s tough for sure. The views were great and several places to stop for pictures. Pretty crowded when we went, on a weekday during mid morning. We didn’t come from valley, we took the mount Sanitas trail and it was hard!

This is NOT A lightly trafficked trail. There were throngs of people. I suppose it’s nice if you’re a local, but I would not drive out of my way to come here again. If I hadn’t driven two and a half hours already, I’d have left when we had to drive away from the park and find side-street parking in a neighborhood.

Great workout and doesn’t take too long

What a beautiful trail and canyon very peaceful. Lots of animals to be seen. Amazing rock formation and imense geological variety.

This is a great hike if you are looking for a short and moderate to rigorous workout with great views. Ascending Mount Sanitas took me about 1 hour with several short water breaks. It is moderately steep and rocky. There is no shade 85% of the way up. Pretty views en route and at the summit. Descending through East Ridge was rough. I may have taken a wrong turn and ended up off the actual trail because it was loose rock almost the entire way down, pretty dangerous, and I ended up entering the valley trail further down.

this is a incredibly steep incline if you go via the mount sanitas trail route and not the valley. the valley offers no shade. the trail is steep and very rocky with a heck of a lot of stairs. there is no flat on this trail it is all up. parts of the trail were rock scrambling. dogs are welcome on leash and it's supposed to be a green tag trail. however every dog except mine were off leash and not all of them were voice recall trained. when I called out to people that my dog was not nice several had to run to grab their dogs. If you have a dog who has some leash aggression issues I would not take on this trail. many other trails in area with less dogs. this one has a lot and it was a Friday morning at 10 when we started!

great views at the top and was a great workout but I was in the mood for a moderate trail. I would have called this one difficult and I would have probably enjoyed it more had I been in the mood for a difficult trail that day

there is some shade offered the way of the mount sanitas trail and some nice stopping points to take pictures or chill.

this was a great hike and it is steep and rocky but well worth it when you get to the top and see the beautiful view.
