Ptarmigan Traverse
You want beauty, remoteness, challenge, and reward — look no further
This majestic summer alpine traverse, considered the best in the Cascade Range, is the oldest and most famous high route in the Pacific Northwest. It epitomizes remoteness, wildness, and alpine adventure. The beauty of this area – especially the central portion and the White Rock Lakes area – is beyond words. Along the way, you’ll enjoy spectacular campsites, climb some peaks, and take a soulful journey away from all the “noise and haste” of modern life.

Trip Perks
Along with the Isolation Traverse and routes in the Pickets, the Ptarmigan Traverse is among the rare glaciated adventures left in the lower 48 of the U.S. that gets you out in an environment disappearing before our eyes. You’ll enjoy straightforward glacier travel and from your high traverse enjoy views of the North Cascades extensive, though receding glaciers. And when you step off the snow, you’ll enjoy some pleasant alpine rock on the summits accessible during the trip, including the inaccessible Dome Peak.
And of course, you’ll be camping Mountain Madness style:
- We’ll drive you to the trailhead and back!
- Give you shelter from the storm — tents are provided!
- Provide meals and the culinary skills of your guide — food and cooking are on us!

Description
Four members of the Ptarmigan Climbing Club made the first crossing of this route in July 1938. For thirteen days, Calder Bressler, Bill Cox, Ray Clough and Tom Myers pioneered the entire route from Dome Peak to Cascade Pass and made many first ascents. Their route covered the Cascade Crest from Cascade Pass to a valley just north of Glacier Peak, in the Glacier Peak Wilderness area. They climbed an incredible number of peaks along the way – in fast and light alpine style – and it is a widely held belief that their exact itinerary has never been repeated, especially taking into account the peaks climbed in the northern section of the traverse.
For climbers this trip offers numerous summit opportunities, all in an incredible wilderness setting. Ascents of Magic and Mix Up, La Conte and Sentinel, Spire and Dome, are just a few of the climbs possible on this trip. The Ptarmigan Traverse is simply a must-do for any lover of mountain travel.
This trip involves the following:
- Advanced backpacking and cross-country travel with loads to 40 – 50 pounds
- Remoteness and a mini-expedition feel
- Basic rock and snow climbing
- Glacier travel
- Climbers should be in excellent physical condition and competent on varied alpine terrain.

Trip Insurance
We strongly recommend the purchase of travel cancellation insurance to protect you from the unexpected. You aren’t likely to think of it now, but people do get ill, break a bone, have a family emergency or get assigned to a last-minute business trip. If you are in remote areas, please note that emergency rescue & evacuation can be very expensive.
We also strongly urge you to consider rescue and evacuation insurance if your own policy does not provide the coverage needed. Services available may include, but are not limited to, helicopter evacuation, medical care, etc.
If you choose not to purchase insurance, you assume full responsibility for any expenses incurred in the event of a medical emergency and/or evacuation, as well as for trip cancellation, interruption, lost luggage, etc. We are not the experts and therefore ask that you please consult our travel insurance partner directly with any specific questions.
