"This hike was long and hot! Gorgeous views from the top! I forgot my lunch in the car and had to hike back down + up from .8! Hydration and cooling down at the streams was a huge part of this hike!!" — dennis-van-amburgh • Aug 10, 2025
"Fantastic backpack camping hike with Tina and Dianne. Beautiful weather and loved taking bushwhacks that avoided several stream crossings. Steeper part was at the beginning when we were fresh. Gray jays were out at the top. Found all markers. Caught sunset and sunrise! A little smoke from Canadian fires. Down wasn’t too bad even with big pack and tired legs. Rain started when we got in the car! #26 ✅!" — lfrancois • Jul 26, 2025
"This fall hike finishes up our seasonal gridding of Isolation. A cool and cloudy day with intermittent sprinkles. Lots of fog to look at via the summit. Trail still has tons of water and mud. Lovely 13 mile rock hop." — Alohabuffy • Oct 11, 2023
"Ahh Mt. Isolation. The hike I will never do again. This one was the most mentally draining hike as you hike up to 5,200 feet to descend to Mt. Isolation. The long trek out Rocky Branch wasn't a picnic either. Engine Hill, you are not my friend as you claim to be easy but after hiking 10 miles, I am not interested in chugging up a small steady hill to get off the trails. We went up Glen Boulder which was cool to see up close. We had a cool weather day but nice views as it wasn't cloudy. Isolation does have a nice view of Washington. Over 13 miles in 11 hours of hiking time. Temperature at the start was 38 degrees and then it warmed up to 51 at the end. " — GreggC • Sep 17, 2022
"Molly and I decided to hike Isolation so she could pick up a good peak for Grid. The parking lot was packed. A lot of people on the trail. We hiked to the Engine Hill bushwack and followed that. We crossed a river and was unsure of where we were. Turns out, the broken out trail was following the Iso Express, which I had never been on. This cut off roughly a mile each way and plopped us out on the Davis Path. But for awhile, I was clueless as to where we were in relation to Isolation Tr. We reached the summit and it was mostly a clear day. We hiked out and made fast time coming out. " — newenglandwarrior • Mar 5, 2022
"OMG this trail is insane. I went up glen boulder and boy I thought that was tough. Once I reached the summit my legs gave out while I had lunch. The views however from glen boulder, along the trail, and the summit were spectacular. This is a very difficult hike. Could not have made it without the hiking buddies group. Took us about 12 hours to complete this hike. Coming quite a distance away and being new to hiking I drove there and home the same day. Making for a 22 hour day. HOW FUN!" — MadHobbyist • Sep 25, 2021
"A west to east traverse with the girlfriend for Isolation. Went up Crawford Path to Mizpah Tr, then down Dry River Cutoff, then up Iso West to Davis Path. We took Rocky Branch Tr out to Pinkham Notch. Heard a moose on the hike. I gridded out Isolation." — newenglandwarrior • Oct 10, 2020
"Started on Tuckerman's Ravine trail to Hermit Lake. From there took the Boott Spur Link to Boott Spur. After summiting Boott Spur hiked on the Davis Path all the way to Isolation. Hiked back Davis Path to Glen Boulder Trail and out Glen Boulder. Short road walk back to Pinkham Notch. Number 46 of 48 NH4K." — dmcosker • Aug 22, 2020
"A traverse of the Davis Path, from one end to the other. Teamed up with Denise, we went up Ammo, then down Davis Path, hitting some peaks on the way. A long day but lots of fun." — newenglandwarrior • Aug 14, 2020
"The long way to Isolation. Red-lining inspired. About 20 miles, doing a loop from Jericho Rd. Rocky Branch South had some tricky spots to follow. Route finding needed anywhere the trail was near a river. The rest of the loop hike went great. " — newenglandwarrior • Aug 23, 2019
