West Ridge of Forbidden
One of North America’s most sought after alpine challenges, the West Ridge of Forbidden Peak is an exposed and engaging route. Combining glacier travel, snow climbing, scrambling and multipitch rock climbing, you’ll get the full alpine experience as you ascend this world class objective. The summit ridge provides excellent climbing on high quality rock rarely found in the alpine. This route is deserving of its place in the Fifty Classic Climbs of North America and is a route worth daydreaming about.
$1300 - $1750

Here’s What To Expect

Itinerary

Day 1 After a gear check, we’ll travel to the Boston Basin Trailhead and ascend the steep climber’s trail through the forest and up to Boston Basin. We’ll ascend to below the South Face of Forbidden Peak and make camp at the bivy. A review of skills and an early dinner will prepare you for the big day to come.

Day 2 With an early start we’ll ascend the glacier to approach the West Ridge. Some scrambling or steep snow climbing, depending on the season, will bring you to the crest of the ridge.

From here, high quality alpine rock climbing will deliver you to the dramatic summit of Forbidden Peak. Views in all directions over the heart of the North Cascades reward your efforts before a careful descent of the route to camp.

Day 3 We’ll sleep in and enjoy a leisurely breakfast before descending the climber’s trail to the cars. This general itinerary is subject to change based on weather, route conditions and participant skill level, among other factors.

Trip Reviews
“I have skied with all of the guides at CMA and have had great experiences. They are passionate about their craft, and it shows in the experiences they provide. They know where to find the best skiing and have extensive knowledge of the local terrain.”
- Patrick

“They do the essentials really well: they’re professional, knowledgeable and competent, great teachers, and always keep an eye on safety as every guide service must. What sets them apart for me is that they do all that AND make it FUN. Some of the best times I’ve ever had in the mountains are with this crew. I highly recommend them!”

- Chase

“I hired this guide crew for technical education and then returned for their recreational guiding services. I’ll continue to lean on Cascade Mountain Ascents to bring me further into the backcountry and advance my technical skills in the mountains.”

Technical Programs

Cascade Mountain Ascents pays guides more when they are working in terrain that is more involved or poses higher objective hazard. Therefore, a surcharge is added to trips we deem Challenging ($100) and Complex ($200). A custom surcharge may apply to non-standard programs and will be worked out by the guide and administrative staff along with the guest(s) during program design. Here’s more information on Technical Program Surcharges.
