Conditions summary as of September 9, 2026

South Kinsman is currently manageable but conditions are deteriorating fast, with heavy rain and strong winds moving in through Wednesday night and Thursday. Trails are already wet and muddy from recent rain, and ridge winds gusting into the 45-55 mph range will make the exposed sections near the summit quite uncomfortable and slippery. Friday offers a drier, calmer window and is the better choice for this hike.

Expect a swing of about 10°F between the trailhead and summit, with winds increasing dramatically from ~25 mph at the trailhead to 45-55 mph near treeline and the summit; pack a windproof layer to don once you approach treeline, since wind chill near the top will hover in the upper 30s even though air temperature stays above freezing.

Best Hiking Window

Friday, September 11 in the early morning through midday — precipitation chance is low (6%) and winds should be calmer, though it will be noticeably colder

Hazards
Wet, muddy, and slippery footing especially on rock ledges and roots
Heavy rain and near-100% precipitation chance Wednesday night into Thursday
Strong summit-area winds (45-55 mph) causing poor balance on exposed rock
Reduced visibility from clouds/fog at higher elevations
Saturated ground increasing risk of slips near stream crossings and brook-adjacent trail sections
Cooling temperatures dropping into low 30s by Friday, raising chance of overnight frost on wet rock
Recommended Gear
Waterproof, sturdy hiking boots with good tread
Trekking poles for slippery rock and mud
Full rain shell (jacket and pants)
Extra insulating layer for wind chill at treeline and summit
Warm hat and gloves for exposed sections
Headlamp with extra batteries in case of delayed return
Map/compass or GPS in case of fog obscuring the ridge

Trail: Mt. Kinsman Trail, Kinsman Ridge Trail

Conditions: Dry Trail, Wet/Slippery Rock

“A FINE day in the forest was had. I have not used this trail due to the landowners squabble. As a North Country resident who lives ten minutes away, these folks routinely air their dirty laundry in op-eds about eachother and have had articles written about them about how NOT to do business up here. I really did not want to patronize them or give them any support due to this. I likely still wont, but credit is due to the work they have done from the parking lot (which they complained about the old one was visible, but then moved the new one behind their house, which they where smoking pot out there at 8am). It's cruiser. Wet trails, minor erosion is starting to be evident (some more than minor) on KRT. Another trail being loved to death. No issues, car to car in about 5h”

Trail: Mt. Kinsman Trail, Kinsman Ridge Trail, Reel Brook Trail, Bald Peak Spur

Conditions: Dry Trail, Mud - Minor/Avoidable

“I biked from Reel Brook to the new Mt. Kinsman trailhead. It's a quick, mostly downhill run. Bald Peak does have a nice western view, but IMO it would not be worth the $20 car parking fee (I'm from Maine) if it had been my only objective for the day. Of note, I did meet a hiker on the way up who used the old trailhead to access the trail without paying the fee. The Kinsman Flume is very impressive and somewhat scary since you can get right to the edge of its impressive drop. Nice views along the ridge and met many NOBOs and one SOBO. The descent to Harrington Pond is challenging; I think this might be a risky route if the ledges are wet. It took me longer than the 30 minute AMC guide time to descend the mile to Harrington Pond; lots of sitting down and careful sliding from foothold to foothold. Reel Brook was a very pleasant and easy walk down after the hours of scrambling on the Ridge.”

Trail: Basin-Cascades Trail, Cascade Brook Trail, Fishin' Jimmy Trail, Kinsman Ridge Trail

Conditions: Dry Trail, Mud - Minor/Avoidable

“The ledges were pretty much dry making for safe footing. I hadn't been on Basin-Cascades and Cascade Brook trails for decades, so it was like seeing a new trail. They are an easy way to get up to the Lonesome Lake hut with some falls and pools to enjoy. Great view from the docks at Lonesome Lake and at the summits. At North Kinsman one can descend from the initial ledge that looks to Lonesome Lake to arrive at the second ledge that allows a view down to Kinsman Pond. There are a couple of minor ledges and a few branches extending into the short path to this lower ledge. There are two knobs on South Kinsman. The south knob has the best views and the "throne seat: on the large cairn.. Lots of hikers out today. I met hikers from all the New England states coming from both the east and west approaches to the ridge. Also met many AT thru and section hikers from many US states as well as Germany.”
