"Perfect day for a long climb. We began with the Glen Boulder Trail, which was beautiful and didn't feel as long as I expected. By the time we summitted--crossing via the Davis Path, and the very muddy Isolation spur--we were definitely glad to have left a car at the Rocky Branch trailhead. Re-ascending 1,500 feet to the Glen Boulder/Davis junction would have been a little much for us. In spite of this, I fell in love with the Glen Boulder Tr(!), but might never use the Rocky Branch or Isolation trails again. So wet and tedious! Long hike, but great weather, and beautiful views!" - gooner, Aug 31, 2018
"Hiked up Ammonoosuc Ravine Trail to Camel Trail and crossed to Davis Path. Hiked down to Isolation Spur and up to summit. Had lunch and fed a Grey Jay, then headed down. Took Davis Path to Isolation Trail, to Rocky Branch # 2, and on down to Rt. 16. One water crossing was quite high, and I had to go downstream a bit to get across. Pam took off her boots and pants and waded through the deeper area instead. Both Isolation and Rocky Branch had loads of mud and water and were major rock hops for most of the trails. Finally finished my 48 4000 footers! Yay! " - Hufflepuff, Jul 29, 2018
"The plan was for our group to check out the Alpine Gardens, but with the weather being iffy, we went to Isolation instead via Glen Boulder Tr. Steep climb. Weather wasn't the greatest for being above treeline. Cloudy and windy. We went over to Isolation and Sarah H picked up her 47th NH48. At this point, the weather was much nicer and it was beautiful on the return. Great hike for the 7 of us. " - newenglandwarrior, Jun 8, 2018
"Rocky branch to the bushwhack though the birch glade. So beautiful. No tracks so we made our own. Ran into a few sketchy river crossings with thin ice and fast moving water. The summit was cloud free but chilly...we enjoyed the views of the presidential s for about 3 minutes. Amazing day!" - shay-shay, Jan 18, 2018
"Tough day of hiking overall. My first time hiking in icy/snowy conditions, but I must say... microspikes are AWESOME! We got a late start, didn't get on the trail until 10:15 so we descended in the dark. Lots of blowdowns along the Isolation Trail just before the intersection with Davis Path. Views from the summit were stunning." - kpreston21, Nov 11, 2017
