A very good trail. Clockwise makes it largely a gradual uphill, good work out. I enjoyed the creek very much.

Beautiful quick hike that’s not too demanding for out-of-towners. Definitely steady elevation gain that you’ll feel but not terrible. Trail leads to many others. Great views of the mountains if you’re on a time crunch. Parking lot not very big and very crowded on weekend afternoon but easy to park in the neighborhood.

Beautiful trail with Mountain View’s and valley views. Was confused during some of the road crossings and switchbacks. Lots of tree cover. Some snow but not much!

Short, moderate difficulty trail. Nice that it's close to town.

Great trail with great views throughout. Be prepared for a lot of ice on the trails near the top and the west side.

Classic boulder hike. Steep but relatively short with great views of the arch and Boulder down below (and Denver way in the distance on a clear day).

Great, challenging trail. The views are worth it.

Amazing view from the top from the beautiful arch and the overlook of boulder. I would rate is more moderate then hard. I recommend doing it during the week if you want to avoid crowds. It is a very popular hike.

I disagree that this is marked as a hard trail. I would say it’s pretty moderate at best. It does have decent elevation gain in a pretty short distance, so maybe that’s where the rating comes in. The views at the top are beautiful though, and I would recommend it if you are looking for a shorter hike that’s a good work out

Was a great trail! Was very worth it once you get there!

Like to think of myself and my best friend as experienced hikers... 90% of the hike was super moderate with beautiful views of the mountains & city.. but the last 10% of hiking turns into free climb, rock climbing. Scaled the rocks to up where I thought the entrance of the cave would be and could not find it. Honestly blindsided by extremely foul orders once arriving to where I thought the cave entrance would be... someone defaced the top area with feces. Heads up to anyone looking to climb to the top.

Such a shame this trail is now closed to MTB’ers on Saturdays and Wednesday’s.... but apparently hikers find it “peaceful” now....sure. But, it really doesn’t matter anyways because the road to get to Betasso is basically closed due to the rock slide maintenance up Canyon Road. The road is completely closed 10:00am - 2:00pm and supposedly this could go on until 2021. Save yourself the time and energy and don’t try and go to this trail is bike riding, wayyyyy better trails to hit up in the area.
