Conditions summary as of October 17, 2026
A cold front has dropped temperatures well below freezing, with rain changing to snow and ice, so expect slick, snow- and ice-glazed trails from the trailhead up, on top of strong winds and wind chills near 0°F. Middle Tripyramid is wooded, which blunts the wind, but the steep ledges and rock sections will be treacherous when glazed with ice. Conditions improve markedly Sunday under clearing skies and lighter winds.
The freezing level sits between roughly 1,400 and 3,970 ft, so expect snow and ice for essentially the whole hike, with trailhead around 28-42°F and the summit around 20-35°F (wind chill near -3°F). Dress in a warm, wind-blocking layering system from the start, carry extra insulation for the upper ridge, and expect winds to increase noticeably above about 3,000 ft even though the summit itself is wooded.
Best Hiking Window
Saturday is the harshest day, so postpone if possible. Sunday is the better option, with a late-morning start once temperatures start rising and clear skies and lighter winds arrive, finishing well before the 6:00 PM sunset. If hiking Saturday, start early and be prepared to turn back if icing worsens.

Trail: Pine Bend Brook Trail, Mt. Tripyramid Trail
Conditions: Dry Trail, Wet Trail, Wet/Slippery Rock, Mud - Minor/Avoidable, Mud - Significant
“Over all the trails were in great condition. The rocky/boulder field and steep ledge sections were still a little dew covered from the prior night, some rocks/boulders/ledges were a bit slippery.”
Trail: Livermore trail, Mount Tripyramid Trail
Conditions: Dry Trail, Mud - Minor/Avoidable
“Hiked the lollipop that included North Slide and South Slide for the Terrifying 25 list. Both were dry but do require significant scrambling and hand/foot climbing in areas. Loose rock is more prevalent on south slide leading to some spots that are slippery underfoot. The Tripyramids themselves are beautiful and a fun walk from one to the next w/o much strain. Trail itself is in good condition w/ only 1 blowdown on the entire route.”
Trail: Livermore Road, Mt. Tripyramid Trail
Conditions: Dry Trail, Wet Trail, Wet/Slippery Rock, Mud - Minor/Avoidable
“Second time for me on North Slide and first time solo. The lower slabs were dry (don't attempt when wet), but still present challenges in a couple spots. Stay left until you get higher up and when it turns to loose rock, angle to the right. Summits are all almost comoletely wooded now in summer. South Side is better footing for descent.”
