Wednesday afternoon into Wednesday evening offers the best conditions as high pressure builds and storms taper. Avoid Tuesday entirely due to the severe thunderstorm and extreme heat threat. Start Wednesday early to allow morning showers to clear before committing to the upper trail.
Trail: Bike path, Liberty Spring Trail, Franconia Ridge Trail, Flume Slide Trail
Conditions: Wet Trail
“Mostly posting this to note the new-ish, blow-down (birch) on Flume. Probably 2 miles from the trail junction on Liberty Springs.”
Trail: Pemi East Side Trail, bushwhack, Osseo Trail, Franconia Ridge Trail, Garfield Ridge Trail, Twin Brook Trail, Frost Trail, Twinway, West Bond Spur, Bondcliff Trail, Lincoln Woods Trail
Conditions: Dry Trail, Wet Trail, Wet/Slippery Rock, Standing/Running Water on Trail, Mud - Minor/Avoidable
“Standard (almost) Pemi Loop from Lincoln Woods. This is the easiest loop, and it's still possible, but I wouldn't recommend it. I took the East Side trail about 1.7 miles and then broke toward the river to cross. Look for the spot where the river is straight and wide, with a large eroded dirt cliff on the far side. This cliff is directly at the end of the Osseo Trail. I crossed toward the downstream end of the cliff and was never more than thigh deep. The water is cold and moving pretty fast. I'd recommend poles or a stick for balance. Once I hit the shore, there was a trail of orange tapes leading up to the LW Trail. Turn RIGHT and you'll see the Osseo in a hundred yards or so. I left my wet shoes there for the return trip, but you might consider carrying them so you can cross farther up (less water) on the way back. I wouldn't recommend a barefoot crossing, and would consider scoping/trying out the crossing(s) on a day when you are not doing the hike. I spent a lot of time and energy on that. Crossing back when it's dark and you're tired will be difficult.”
Trail: Pemi Trail, Whitehouse Trail, Liberty Spring Trail, Franconia Ridge Trail
Conditions: Dry Trail, Wet Trail, Mud - Minor/Avoidable
“I almost pivoted to crash Lynn and Rhonda's hike after bumping into Rhonda in the McD's bathroom but decided to stick with the original plan. The Pemi trail was in great shape as was Liberty Springs. The rocks were nice and dry which made for a slightly speedier ascent and descent and no slips or falls. Franconia Ridge was in great shape and was mostly dry. There were a few muddy areas but the mud was drying out nicely and was supportive and not squelchy. Views were lovely this morning until the black flies arrived.”

5 incidents on file · drawn from NH Fish and Game releases and regional reporting
Casey Cullinan, 30, of Warwick, RI, and William Becker, 30, of Hope Valley, RI
Two hikers became stranded near the top of the Flume Slide on March 19, 2026, due to extremely icy trail conditions that prevented them from ascending or descending. They had micro spikes but not crampons, and had already spent one night camping. Mountain Rescue Service and Pemi Valley Search and Rescue Team used ropes, crampons, and harnesses to lower the hikers to safety, returning to the trailhead at 11:10 p.m.
43-year-old male hiker from Kingston, NH
Christopher Ricca, 43, of Kingston, NH, began suffering from heat-related illness on Wednesday evening while hiking the Pemi Loop between Mt. Liberty and Mt. Flume with his nephew. His nephew hiked out via the Osseo Trail to summon help while Ricca attempted to continue on his own. Conservation Officers and PVSAR members reached Ricca at the summit of Mt. Flume and carried him out via the Osseo Trail, with Ricca reaching the parking lot at approximately 6:20 p.m. on July 17, 2025.
Jonathan Long, 26, leading three youths ages 13-14 from the Boston, MA area
The group was descending the Flume Slide Trail about 3 miles from the trailhead but could not continue because they had no lights and no overnight gear. Because of cold temperatures and the group's unprepared state, a rescue was initiated; officers provided lights and food so they could descend.
52-year-old male from Canton, MA
On June 12, 2023, a 52-year-old Massachusetts man slipped on wet rocks and fell approximately 15 feet while ascending Flume Slide Trail about 3.5 miles from the bike path. Two Conservation Officers and Pemi Valley Search and Rescue Team volunteers responded, but the hiker was ultimately able to self-evacuate to the trailhead. He was transported by ambulance to Littleton Regional Healthcare for treatment of serious injuries.
22-year-old male from Acton, Massachusetts
Benoit Armangau, age 22, accidentally stabbed himself in a lower extremity while cutting evergreen boughs for bedding near the summit of Mt. Flume on April 30, 2014, leaving him unable to walk unassisted. Conservation Officers reached the pair at 1:45 a.m. on May 1 amid snow depths up to two feet and cold rain, stabilizing the injury overnight. Rescuers and volunteers evacuated him to the Liberty Spring Trailhead by approximately 1:30 p.m. on May 1.
