Ski the Isolation Traverse

The Isolation Traverse is one of the great North Cascades ski mountaineering adventures, combining some of the best fall-line skiing of any major Cascades traverse with an incredible journey through the remote heart of North Cascades National Park. For experienced backcountry skiers looking for a serious multi-day ski traverse, few trips in Washington can match its combination of great skiing, massive glaciers, spectacular scenery, and true wilderness.

Over the course of the Isolation Traverse, we cross more than a dozen glaciers while linking remote valleys, high alpine passes, sustained climbs, and long, aesthetic ski descents. Unlike many big ski traverses, the Isolation delivers an impressive amount of quality downhill skiing, with beautiful fall-line descents day after day. It’s big, engaging terrain where efficient travel, route-finding, snowpack assessment, and good mountain judgment are all part of the adventure.

True to its name, this is one of the wildest ski traverses in the North Cascades. It’s entirely possible to travel for days without seeing another person, ski track, camp, or sign of recent human travel. Surrounded by enormous peaks and rarely visited glaciers, the Isolation Traverse has the feel of a remote ski expedition without ever leaving Washington.

This is not a first multi-day backcountry ski tour. It’s designed for strong, experienced skiers with the fitness for consecutive big days and a desire to travel deep into the mountains. For those ready for it, the Isolation Traverse delivers phenomenal skiing, huge terrain, incredible camps, and one of the most unforgettable guided ski mountaineering trips in Washington State.
