Green Mountain Loop is a 6 mile lightly trafficked loop trail located near Boulder, CO that features beautiful wild flowers and is rated as difficult. The trail is primarily used for hiking and trail running and is accessible from March until November. Dogs are also able to use this trail.
A popular peak hike providing views of the Indian Peaks and Boulder There is a map at the trailhead. Head up Bluebell trail to Gregory canyon trailhead (there is a fee to park here). From here either way is fun, but clockwise is a little harder. Travel up Gregory canyon to the cabin with outhouses. From there take the trail up the north ridge to the peak. Enjoy the views on a clear day and head down when ready. For an extra workout, go back on Bluebell, otherwise head down the baseline trail to the trailhead.
Amazing workout hike! I more enjoyed the clockwise, even if is steeper. The trail is way beautiful than GC and Ranger. Trail marks should be better and accurate in entire park not only on this trail. You take a wrong way easily if you are not familiar with area.
Great trail, maybe better marked in certain areas. The 'hard' rating is spot on if you go clockwise on the loop. Once you get to the EM Greenman trail the worst is behind you.
Very fun trail.
Was trying to find the Flatirons trailhead and drove past it and up the mountain. This trail was entirely covered by brush and more or less difficult to hike. I was hiking down into the canyon and while it was nice to be in the shade, I struggled to enjoy myself. No easy places to take a break, lots of annoying brush or sticks, and nothing great to look at. The lookout views on the way driving down the mountain were much more worthwhile for the views.
HEADS UP: there is a spot on this trail that says it does not allow dogs at all... We had no choice but to take our dogs through that area to complete the loop as shown here.
This hike is difficult. The wild flowers are beautiful. Unfortunately it was cloudy today so we didn't get to see the peaks at the top. I would suggest using this app to track yourself, it can be confusing.
Fun hike and great views on your way up. Not the best views from the summit, but rewarding and fun hike to do in Boulder.
Great Day hike with amazing views of several 14ers at the top.
I loved the first half of this trek...took the Gregory Canyon trail to Ranger, nice steady climb but not too painful, and great views. Coming down the other side was hell on the knees and a lot of scrambling; next time I'll be going back down the way I came! Beautiful hike though, and not super busy in the early morning.
Tim an Giora and Kristen and I hiked up the steep amp theater trail to the top of green mountain. Loved the kiosk at the top showing all the mountains around. Trail was steep and rocky. The down ranger and canyon was longer and smoother footing. Loved the old ranger lodge. 7 mile round trip. Nice trees. Not much water. A few great views of Boulder.
Great challenging hike for a great workout! Went up Amphitheater trail which was straight up for miles, so be ready! It's worth it as you see awesome views all the way to the top. I took Ranger and Canyon the way back. If you want to do a more gradual climb take that way first.
This is a great loop, difficult at parts which will work your cardio but well worth it once you reach the summit. The trails are well worn and easy to follow with mostly shaded by beautiful trees.
This was a great hike! Definitely a steady, steep climb all the way through Gregory Canyon and Ranger Trail up to the summit. With taking a lot of breaks to drink water and take in the views, the entire hike took me 3 hours and 45 minutes. I recommend starting early, around 6:30, as I did to beat the crowds!
intended to take Gregory canyon but remembered there was trail with a ladder which I had always wanted to do so... started at Chautauqua, took trail to Gregory canyon parking lot, started at the saddle rock trail and ended up doing the full loop back down Gregory canyon. it was a real challenge but rewarding, a great workout and wonderful views.
This is a great and challenging hike. There are many ways to get to the summit. We started at the Chataqua Trailhead and took the Bluebell trail to the loop itself. Took the ampitheather-saddle rock half of the loop up to the summit, then took Ranger and Gregory Canyon down back to Chataqua. It is a lot of steep hiking to the top and there are a couple short fun sections where you get to climb a ladder and do some gentle scrambling on rocks. The summit is fantastic and you can use the plaque on top to identify the surrounding mountains! Bring lots of water and energizing snacks. Definitely a worthwhile half day hike.
Great and challenging hike. We got a bit turned around at the start but used Bluebell Trail and Gregory trailhead. Going clockwise on the loop was harder and steeper to the summit. We had plenty of shade throughout the entire hike. Be mindful of which trail you are on as its easy to end up on the trail back to flagstaff after summiting if you are going clockwise. We used gps via all trails and was helpful when we were off corse. We ended up adding a couple miles in the beginning finding the main loop. The summit was crowded....with people and butterfly's. Great day in beautiful Colorado!
