Forbidden Peak West Ridge
Intermediate Summit Climb
Located in a vigorous alpine setting in the heart of the North Cascade National Park, an ascent of 8,815 foot Forbidden Peak offers excellent views of the surrounding peaks and the massive Boston Glacier and is one of the most classic climbs in the park. Heralded as one of the “Fifty Classic Climbs in North America,” our route on the West Ridge is an aspiring alpinist’s dream. The route consists of mid-fifth class climbing and 40°-50° snow and ice before joining an exposed rock ridge. Join us on this rugged North Cascades classic for an unforgettable experience.
Each year we offer one scheduled climb at a discounted rate and during the “prime” of the season. Otherwise, all other climbs can be scheduled and priced on a custom basis.

Description
Following a pre-dawn start, we ascend up and onto the pocket glacier at the base of the spectacular South Face of Forbidden and traverse to the West Ridge Couloir. We climb this 40 – 50 degree snow gulley for about 500 feet, finally breaking out into broken easy rock that leads to the crest of the West Ridge. Mountain boots are exchanged for rock shoes and then the fun begins! Amazingly solid Skagit gneiss provides excellent footing and even better views. Forbidden’s West Ridge represents everything good about alpine rock climbing — sound rock, exciting exposure, engaging climbing on varied terrain, true cruxes, and a tiny summit. This climb is guaranteed to bring a smile to your face! Descent is made by reversing the ascent route – a combination of rappelling, lowering, and belayed down climbing, bring us back to the glacier where success makes for fleet feet back to camp.
This is an intermediate level climb. Similar and previous experience required.
This climb involves the following:
- Glacier travel, steep snow, and exposed alpine rock
- Strenuous approach of 5 — 6 hours
- Snow and ice couloir to 50 degrees
- Climbers should have the ability to follow 5.6 rock with a day pack and move steadily for 10 – 12 hours
- Taxing and long descent involving belayed down climbing and rappelling
- 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.
To protect against losses due to illness, accident, or other unforeseen circumstances, Mountain Madness strongly recommends the purchase of travel insurance as soon as possible after making a deposit. Mountain Madness has partnered with Redpoint Resolutions as our preferred travel insurance provider. Redpoint’s Ripcord Rescue Travel Insurance™ is designed for adventurers.

Forbidden Peak West Ridge Day by Day
-
Day 1
The drive from Seattle to Marblemount, gateway to the North Cascades National Park, takes about 2.5 hours. From there, the Cascade River Road provides great access to the peaks that surround Cascade Pass and the famed Boston Basin — home to Torment, Sahale, Sharkfin and Forbidden Peaks. After leaving the trailhead, we gain 2,500 feet / 762 meters by climbing up a steep, rugged trail into Boston Basin at 5,700 feet / 1737 meters. Camp is made either at tree line, or in the upper basin below the unnamed pocket glacier that provides access to the West Ridge route.
-
Day 2
We start the climb with a pre-dawn start, approaching on glacier and then a steep snow gulley to the West Ridge. From there the route follows the ridge to.the summit. This is a long day — climbers can expect a 10 – 12 hour ascent and return to camp.
-
Day 3
Most parties find it unreasonable to attempt to hike out after the previous day’s climb and therefore elect to spend the night in Boston Basin. Hiking out on Day 3 makes for a much more doable, relaxing, and enjoyable trip. If energy allows, it is highly recommended to explore the area’s abundant alpine flora, waterfalls, and moraines populated by marmots. Expect to be back in Seattle by mid-late afternoon.
Note on Itinerary: Although we do our very best to follow the schedule listed, the very nature of climbing in an alpine environment requires flexibility. This itinerary is subject to change due to inclement weather, unsafe route conditions, and other reasons beyond our control.
