April 9, 2021Still a bit snowy at top of em greenman.
March 3, 2021February 23, 2021Pretty snow covered, but all packed snow. Spikes needed for sure. Beautiful!
February 8, 2021Icy spots near the beginning, end, and the initial descent from the summit on E.M. Greenman. Spikes definitely helpful!
February 7, 2021This trail is one of our faves and we did it last weekend. It was warm but there were still patches of ice. I did it without crampons but they would have been useful at times.
February 1, 2021Hiked 2/1. Icy in many spots among loop. Wore spikes the whole time, but definitely some areas where they’re not necessary. Went up Gregory Canyon Trail & down the other side of the loop. Steeper & icier on the Saddle Rock/Amphitheater side, so keep that in mind when choosing your loop direction!
January 23, 2021Definitely would recommend spikes and poles to manage the icy trails. Even if it’s not visible, there were plenty of points where the ice was covered by a thin layer of dirt that made it really slippery.
January 18, 2021January 2, 2021Beautiful morning hike. Got to the trailhead at first light. Only a couple other cars before me. Had the trail pretty well to myself on the way up. Great views from the top in all directions! I did it with no spikes but they would have been nice in a few spots!
December 26, 2020Loved this trail. My favorite in Boulder so far. Love how forested it is. Spikes helped at beginning and end where it’s very icy.
December 22, 2020Very icy in spots, definitely bring spikes!
December 6, 2020November 21, 2020October 3, 2020September 26, 2020Difficult but beautiful hike!!
September 19, 2020September 14, 2020Nice hike through the forest.
September 13, 2020Great hike. Only one small patch of snow on Sunday 9/12. Enjoyed it even more than Arch, which we did yesterday. Also, a lot less crowded than Arch and more mask wearers. We started both hikes around 9am.
September 12, 2020Steep incline to the top. The decline is pretty slow and rocky. Great views at the top.
September 6, 2020September 3, 2020Challenging up and down. We went by the Ranger Trail, making our hike more spicy!
August 9, 2020Overall a beautiful trail and worth it! The trail completed was about 6.9 miles with a good elevation gain. The ladder on Saddle Rock Trail gets pretty hot!
August 8, 2020August 6, 2020If taking the loop counterclockwise, be sure to take the correct trail on your way back down, connecting to Ranger Trail which is hidden in a sharp right fork that’s easy to miss! I got lost in the scenery and went the wrong way a couple of times, so be sure you know where you’re going - or that your phone is fully charged. Overall one of my fav Boulder hikes!
July 22, 2020July 19, 2020Did this in reverse and skipped Amphitheater. Started on Saddle Rock to E.M. Greenman, then came down Ranger to Gregory Canyon. Last time I did it was in the snow and using Microspikes, this time went a lot quicker with no ice! Took me about 3 hours and 20 minutes at a VERY leisurely pace with a bum ankle.
July 18, 2020Awesome hike to kickoff this weekend in mid-July! Enter the trail loop from the right (counter-clockwise) for an easier ascend (although still difficult). Begin on the left trail (clockwise loop) for the more challenging, technical option.
July 13, 2020Great Monday trail to wake up the body!
