Enjoyable, short, and a good exercise. Close to the road in Gregory canyon, but pretty scenery.

Went counter clockwise and boy it was tough. Trails are not well marked and accidentally went halfway up Gregory canyon again before realizing it. At least it was a nice scramble down. Overgrown with poison ivy everywhere. Long sleeves and pants are a good idea.

We started this hike at 7pm, did it clockwise (via Saddle Rock) and hiked in complete shade, as other reviewers suggested. It was pretty tough to start. I would say it was about 45 minutes to the top, but honestly, I didn’t realize we were at the top when we got there so I didn’t check my watch! If you go clockwise be sure to stop and take in the views on the ascent. Those are the best views of the beautiful mountain range. You don’t get a grand view at the top so stop and enjoy while you ascend. After reaching the highest point, the trail is a lovely walk through the woods mostly on a gradual downhill. Our total trip was just over 2 hours and we were in no particular rush. Very light traffic- only saw 6 other hikers.

Loved the hike!

For a good quick workout, this is a good trail. I went clockwise because it was harder. If you’re a late starter like I am, I would suggest clockwise so you’re in the shade all the way after the initial incline. My recorder logged 3.6 miles, probably could have done the green mountain trail as well with another hour or so logged.

Hiked this trail last Saturday and steady incline entire way up. Parking is very limited and trails are not well marked. We got lost and kept going in circles it felt like. Very jungle like at the beginning with narrow trails but then it opens up. Overall a great workout!

Great hike for early in the season when it’s not too hot. Much of it is shaded, and we enjoyed moving through dense, cool forest and dry grassland. Going clockwise is tough, but having to descend Ampitheater would be even harder, as it is very steep. I recommend the clockwise approach that other reviewers have mentioned!

Great trail with some steady inclines. Nothing too crazy but defiantly a good workout. Plus some of the views are amazing!

Great trail. Agree with the other poster that clockwise makes it easier.

I love this loop. It feels much more removed from the crowds at Chattaqua, is easily accessible, has great views, and is well shaded from the sun. I would recommend this loop to anyone looking for a moderate trail. The amphitheater trail is a bit steep, but if you go clockwise you will have a much easier (and enjoyable) descent

Great hike but extremely difficult without spikes in winter conditions. If you do this during the winter, come prepared.

Thoroughly enjoyed this. We went on a Wednesday morning, so there wasn’t much traffic. A nice and pleasant up and down loop with a few switchbacks, some big rocks, lots of trees, a ladder, and snow. Yes a ladder. And being a dork, I was so excited there was a ladder in the middle of a trail, YAY LADDER! Beautiful snow was throughout the entire trail. In hind site I should’ve grabbed my yaktrax that I decided at the last second I wouldn’t need...but totally do able in the packed snow without them. Would love to do again this spring or summer!

Great challenging hike. Be aware that the first part of the trail is steep, with one section requiring you to climb a ladder if you start with the southern trailhead. If you start with the northern trailhead, its more gradual, but the descend is more steep and you will be descending the ladder. Whichever way you choose, the views are breathtaking and the area is very lush. Also, if you are feeling strong, continue onto EM Greenman to peak Green Mountain, come down Ranger, and then continue down the loop!

Great, beautiful hike! Do the steep part first (enter the loop at the downhill leg of the trail). Dogs loved it. Wear good hiking shoes because the first part of the trail is steep and very rocky and the last part of the trail is loose sand and gravel (gradual decline). The first half of the loop is definitely challenging but so worth it when you reach the top because the views are amazing! Enjoy God's beautiful creation, be safe and have fun!

Beautiful hike - nice mix of steep rocky inclines with flat groomed trails.

A great trail for any hiker. Steep moments but only 3.5 miles. View at the top of the loop worth it and you can keep climbing higher if you are so inclined....

Great hike. Parking is limited, free to boulder residents $5 for non residents. We went on a Saturday around 9:30, off road parking are all full. Fortunately there was someone leaving so we got a spot. It took us 2.5-3 hours from amphitheater to saddle rock then down to Gregory canyon. Gregory which is less steep and much easy on your knees coming down this side. The whole trail are mostly in shade which was very nice! Lots of photo ops along the way.

Great short hike close to the city! We went up Saddle Rock and then down Gregory Canyon. Definitely a good workout and some awesome views of Boulder! Parking is limited at the trailhead and costs $5

So I've actually done this hike 3 times, twice I went up Gregory Canyon and down Saddle Rock, but I liked it better going up Saddle Rock and down Gregory Canyon. Definitely a harder hike going up Saddle Rock. Not as crowded as others near here but still gets busy. I also park at Chatauqua and hike in on Baseline Trail since parking is limited.

Great trail. Longer than 3.3 miles. Just under 5mi if you start at the bottom of the parking lot. Really pretty, well marked. Views are good and trails were well marked. Definitely steep going down saddle rock trail. Maybe go up Saddle Rock amd down gregiry canyo , might be easier on the knees. Killer part of the hike was my black bear siting right near the parking area.

Great hike. Took us about 4 hours with stopping and setting up hammocks. A lot of rocks and steep incline and decline in the beginning and end.

Awesome trail! Lots of shade makes it great for a warm day. If you're like me and your knees prefer steepness going up to coming down, head up "Saddlerock Trail" as it is the down leg of Gregory Canyon. Gregory Canyon is a little less steep going down.

Lovely weeknight hike! Very shaded. Head up Gregory canyon to ranger to green Mountain and down saddlerock. Saddleock up is very strenuous! Tons of wildflowers and wildlife!

My only complaint is the lack of signage about the 20 ft ladder on the portion of the trail that was washed out a few years back--one sign at the top. Luckily the dogs were able to get down along the side of the drop.

The trailhead can get packed and full in the busy season so go early or park near Chataqua and walk over. This is a nice workout of a hike up and up through the beautiful foothills forest but is pretty much all incline with not so much scenic eye candy... UNLESS you take one of the connecting trails (Ranger trail) up to the Green Mountain summit which is fantastic and well worth the extra trip. Also, starting from Realization Point on Flagstaff Rd will help take off a bunch of the elevation gain of the hike and get you closer to the top of Green Mountain for the beautiful views. Definitely great exercise when starting from the bottom!!

One of the best hikes I've been on! There are great views and strenuous activity. Lots of snowmelt and packed snow in shady spots, be careful getting down!
