This was an exhilarating hike! Just the right amount of everything. We were unprepared for how cold/snowy it would be at the top of the mountain. Lesson learned. Also should note that this was moderately trafficked and most people had masks on their face or person and had a practice of putting them on when they saw ours.

Probably my favorite hike in Boulder, gives you the workout you want with great views to accompany you along the way. A must hike for sure.

I came on a weekday around 5:45PM and there wasn't any parking in the parking lot but street parking was available. Gregory Canyon is great! Most of this is shaded, and there's not really a "top" or a viewpoint / lookout place as it's a loop. The way down was quite steep as there was a ladder and just in general, loose rocks and steepness but it was manageable.

Very crowded but nice walk next to Boulder - good workout. Suggest going to flatiron or green mountain instead.

Went Saturday June 13. A couple of short challenging stretches but mostly just a great walk in the woods. Some really nice overlook views of Boulder valley.

This was a great trail! It was also a hard trail, especially for hikers that don't hike on a regular basis. However, the payoff was worth it. There were at least two beautiful views of Boulder and the rest of CO on the way up. Then we went around the ridge and were able to get some excellent views of the Rocky Mountain range. All in all a very good hike

Terrible parking situation.. lots of cars lined on the road and mostly full lots on Sunday - as expected. Heavily trafficked area. Definitely a hard hike but good terrain. Use spikes ... i fell several times as I was wearing hiking sandals and they offered minimal traction on the areas where it is mostly dirt. The trails pass through forest/grass area and into a rocky area. Beautiful forest and rocky area with areas of steps throughout. Many wild flowers and great views. There was a picnic area halfway through (closed.)

This trail is tough, but the views at the summit are fantastic! Went clockwise up, and it is much steeper but the way down was very enjoyable. Plan to take a break at the top and take it in—it’s gorgeous.

This trail is a workout the first 1.4 miles. It then flattens out a ways before winding back up through the canyon. You are shaded most of the time which makes it a super fun trail to do on a foggy, overcast day. There are deer all throughout the second half of the climb if you can spot them. Great views of Boulder. The descent gets pretty steep in spots. After you pass the turn off for Amphitheater the trail winds down through a really cool, dense forest.

Such a fun hike! So, we did not go off-trail at all and tracked the hike both on Strava and an Apple Watch and it was definitely 4.0miles long. The hike had a variety and topography including rocky terrain, wooded paths and forest walkway. There was a couple gorgeous overlooks which included much of the Rockys including Longs peak. There is a ladder on the straddle rock trail which was easily descended. Will hike again!

Great hike! Most of our party hiked it without spikes but I'd definitely recommend bringing some type of traction if you have it!

Well, I thought I would take the easy way and go counterclockwise. On the app the elevation looks very gradual going counterclockwise. The elevation gain going counterclockwise was not bad. It was going down, that was very steep and very icy. I would say wear spikes for sure! Regardless the trailer is beautiful and I had amazing time!

Excellent trail! I went counterclockwise up through Gregory Canyon and came down Saddle Rock. Saw a group of four deer in Gregory Canyon. You absolutely need microspikes when you are on Ranger, E.M. Greenman, and parts of Saddle Rock. Packed snow and ice, very slippery. It was a fairly quiet trail for Boulder on a Saturday morning, mostly deep in woods, very serene and beautiful with frozen creeks. Very nice view of the range and Longs at the top. As you continue on you will also get a very nice view of the valley I’ll definitely come back and take this in different directions with different routes, and look forward to also seeing it when the water is flowing.

A decent hike without a ton of elevation. Trail is mostly in the shade so there is a lot of packed snow and ice right now. Yaktrax/micro spikes and trekking poles recommended

Rocky at parts, gets fairly steep and inclined at points. Last part at the top is flat/slightly inclined. Second part of trail where you’d start to loop is closed right now. So I went back down the way I went up.
