Longs Peak Conditions Report
10/8/2025

Winter conditions have taken over on Longs Peak and will likely persist well into June of 2026. Any venture beyond the trailhead will require proper winter equipment, routefinding skills, and knowledge of winter travel. Travelers should expect to encounter snow and ice, extremely cold temperatures, avalanche hazards, and high winds.

Extra warm clothes, waterproof layers, extra food and water, a headlamp, personal first aid kit, and a cell phone are all strongly recommended. Also consider traction devices such as Microspikes or crampons and an ice axe for any travel in the alpine. If you are traveling alone, please tell a friend or family member your plans and take extra care with decision making. Even a minor accident while traveling alone on the mountain can quickly turn into a serious situation. As always, please be prepared to turn around when conditions exceed your abilities.
