Build your own backcountry day
Everything past the groomed Glacier Point Road track. Off-piste skiing, ski touring with skins, ridge traverses, and high-mountain winter camping. These trips use AT (alpine touring) or telemark gear — not classic Nordic skis, not alpine resort gear.
The terrain is real Sierra winter: deep snow, exposed ridges, avalanche-prone slopes, weather that changes fast. The guides have the avalanche education, the route knowledge, and the years of experience that make trips like this safely accessible to clients who couldn't safely do them alone.
A guided day in the backcountry — skin up, ski down, learn the basics. Best entry point.
Classic intro to winter camping with a guide. Camp gear available as a rental if you don't own.
Deeper into the Yosemite winter wilderness with two nights at camp.
Permitted, route-planned, gear-supported. You provide the skills.
Tell the school what you want; they build the trip.
The school has run winter and summer climbing and mountaineering programs in Yosemite for decades. Its guides hold AMGA certifications, avalanche education at the AIARE 1 or 2 level (or AMGA-equivalent), and most have multi-year experience specifically in the Yosemite winter backcountry. They're not transplanted guides running a winter side-gig — this is what they do.
Trip programs require participants to be in good physical condition, have basic ski skills (some trips require AT/touring skill), and be willing to defer to guide judgment on objective hazards. The school will reschedule or modify trips based on avalanche conditions, weather, or other safety factors.
