Conditions summary as of October 7, 2026
Wednesday looks like the better hiking day: dry, clear to increasingly cloudy, with summit highs in the upper 30s to mid 40s and rising winds later in the day. Heavy rain is forecast for Thursday with a cold front, so Thursday is best avoided. Recent light precipitation and freezing overnight temps may leave icy or slick patches on shaded ledges, rock, and slide sections, with days still under 12 hours of daylight.
Expect a temperature drop of about 15-20°F from the trailhead (around 39-55°F) to the summit (around 39-47°F with wind chill near 27°F), with the freezing level starting near or below the lower slopes early in the day. Start with a warm base layer and shed or add layers at the ridge, where the wind picks up and sweat chills quickly.
Best Hiking Window
Wednesday from mid-morning to mid-afternoon, once frost has burned off and before winds and clouds build; finish well before dark and avoid Thursday's heavy rain

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.”
