Mountaineering & expedition guiding, since 2009

Earn the summit.

Cairn is a small, deliberate guiding house. We run a short list of expeditions each year — Denali, Aconcagua, Ama Dablam, and a handful of others — so every climber on the rope gets a guide who has been to the top more times than they can count.

Why climbers choose Cairn

Three commitments guide every trip we run, from the first acclimatization hike to the summit push.

Small teams, real attention

We cap most expeditions at nine climbers and three guides. Nobody on the mountain is a face we learned on day one.

Acclimatization first

Our schedules build in rest and altitude days that other outfits cut for speed. Summit day should be routine, not a gamble.

The call is always the guide's

We turn climbers around before conditions turn dangerous. Our success rate reflects judgment, not pressure to push on.
