Boulder, Colorado Map

Did it in the rain so the views weren't as wonderful as hoped. But still enjoyed it. Did the Sanitas Valley Trail up and the Mt Sanitas trail down. I'm glad I did it this way, the Valley trail was a bit boring at the beginning but the Mt Sanitas trail was beautiful pretty much all the way down. Difficult for an out-of-shape newbie hiker visiting Boulder from sea level like me, but I saw a few people jogging it so if you are fit it shouldn't be a problem.

good trail for hiking and trail running, but I wouldn't bike it unless you are prepared to carry your bike on a few sections of it.

The trail itself is nice, healthy mix of terrain and very few steep ascents. However the trail junctions need some attention, definitely check your map. We ended up heading to Shadow Canyon by mistake and eventually pushed on to Bear Peak, where we found even fewer trail markers, it was a mess and not something we were prepared for. All in all... there was quite a bit of user error here.

Nice quick hike with great views and spread out

Didn’t make it to the top as it’s too foggy today but still lovely will do again when the view will be visible

Challenging like the rating says, the ascent was straight up stair stepping until the switch backs. Trail was a bit hard to follow in spots but markers seemed to magically appear when you needed them most. Also, it had been raining all day so the beaten path wasn't as obvious.

Very Awesome trail! We took the dog and she loved it. Very rocky in areas. It was challenging for me but I pushed through it. My girlfriend and mother did great. Very pretty trail and well worth the hike once you get to the arches. I read these reviews before we went on this trail and y'all weren't lying when you think you made it to the top you haven't haha. I have done one other trail here and this one was my favorite but next time we will go for an easier trail just to give the legs a break. Definitely be prepared with lots of water and don't be afraid to take some breaks. Busy trail so go early if you want to hike with less traffic. And good luck!
