The West Ridge of Forbidden Peak is a crown jewel of the North Cascades, among the “Fifty Classic Climbs of North America.” This 3-day adventure begins with a dramatic approach up to Boston Basin, where we'll set up our high camp with scenic views over the Cascade River valley. The next day we'll climb steep snow leading to the base of the ridge. From there, you’ll climb several pitches of beautiful alpine granite along a knife-edge ridge that soars above glaciers on either side. This climb is best suited for climbers looking to further their alpine and multi-pitch experience. With Skyline, we'll coach and support as you move efficiently and safely across exposed terrain. The reward: standing on the summit of Forbidden Peak with sweeping views of the North Cascades wilderness all around you.

Preparation

Fitness

Climbers should be in excellent physical condition with strong cardiovascular endurance and climbing fitness. The approach to Boston Basin gains significant elevation with a heavy pack, followed by summit day involving glacier travel and several hours of continuous movement on the rock. Training should include uphill hikes with a weighted pack , climbing gym sessions, and cardiovascular training like trail running or stair climbing. The climb demands both sustained physical effort and the ability to move efficiently on exposed rock. Contact us for a free training consultation!

Prior climbing and mountaineering experience is recommended for this objective. The West Ridge features moderate climbing on high-quality granite with excellent exposure. The route combines glacier travel, steep snow climbing, and several pitches of alpine rock along a dramatic knife-edge ridge. Your guides will provide instruction on efficient movement across varied alpine terrain, rope management on the ridge, and safe navigation through exposed sections. Comfort with multi-pitch climbing, basic glacier travel skills, and exposure are important. This climb is ideal for those looking to progress beyond introductory alpine routes and experience a true North Cascades classic.

Altitude

At 8,815 feet, Forbidden Peak sits well below the altitude where most people experience significant effects. The elevation is comparable to many ski resorts and shouldn't pose concerns for healthy climbers. We'll spend a night at high camp in Boston Basin, which provides excellent acclimatization before summit day.

Itinerary

Trip Itinerary

DAY 1
Approach to Boston Basin
Meet your guide at the Cascade River Road trailhead and begin the scenic approach into Boston Basin. The trail climbs steadily through old-growth forest before emerging into subalpine meadows with wildflowers and dramatic views of the surrounding peaks. We'll gain significant elevation with full packs as we make our way to high camp in the basin. Once at camp, we'll set up tents with spectacular views of Forbidden Peak's granite walls rising above. Your guides will review the climbing plan, check gear, and go over rope systems and glacier travel techniques. Enjoy dinner while watching alpenglow on the peaks before resting up for summit day.
DAY 2
Summit Day
Alpine start before dawn to maximize our weather window. We'll climb steep snow and scree to reach the base of the West Ridge Couloir, condition depending, we will ascend this snow couliour or scramble the adjacent Cat Scratch Gully to gain the notch at the start of the ridge proper. From here, the rock climbing begins—several pitches of beautiful granite on a knife-edge ridge with glaciers dropping away on either side. The rock is solid and the moves are moderate, but the exposure is spectacular and the position unforgettable. After reaching the summit at 8,815 feet and taking in panoramic views of the North Cascades, we'll descend via rappels and downclimbing back to the notch, then return down the couloir to high camp. Summit days typically run 10-14 hours depending on conditions and team pace.
DAY 3
Descent to Trailhead
Break camp after breakfast and begin the hike back down to the trailhead. The descent through Boston Basin and the forest below offers one last chance to soak in the beauty of the North Cascades. We'll reflect on the climb and celebrate your ascent of one of the Fifty Classic Climbs of North America. Arrive back at the vehicles by early to mid-afternoon, tired but accomplished.

FAQ's

FAQ's

What makes the West Ridge special compared to other alpine climbs?

The West Ridge combines everything that makes North Cascades climbing legendary: a stunning approach, quality granite, dramatic exposure, glacier travel, and a knife-edge ridge that feels wildly exposed with glaciers on both sides. It's one of the Fifty Classic Climbs of North America for good reason—the position is unforgettable and the rock is excellent. It's the kind of climb that stays with you forever.

What climbing experience do I need for the West Ridge?

This climb is best suited for climbers with some outdoor rock experience; preferabbly with a few multi-pitch climbs under your belt. You should be comfortable with 5.6 climbing, exposure, and moving efficiently in alpine terrain. Prior glacier travel experience is helpful but not required—we'll review techniques before the climb.

What's the camping like?

Boston Basin is deep in North Cascades National Park, accessed via Cascade River Road. The basin itself is one of the most spectacular alpine camps in the Cascades—wildflower meadows surrounded by dramatic granite peaks and glaciers. This is a genuine escape into the mountains

What if the weather turns?

Safety first. Guides may adjust route, timing, or turn around. A summit is never guaranteed; a great experience is.

What's included in the trip and what should I bring?

We provide all group camping gear (tents, stoves, cookware), climbing equipment (ropes, protection, technical gear), and dinners/breakfasts at camp. You're responsible for your personal gear, snacks and lunch for all three days, and any rental items you need (crampons, ice axe, harness, helmet—let us know when booking). You'll need a pack capable of carrying 40-50 lbs for the approach. We'll send a detailed gear list after booking, and we're always available to answer questions about what to bring.

How exposed is the ridge climbing?

The West Ridge features spectacular exposure—it's a true knife-edge with dramatic drop-offs on both sides. This is what makes the climb so memorable and photogenic. The rock is solid, the holds are good, and you'll be on rope with your guide, but you should be genuinely comfortable with heights and airy positions. If you love exposure and alpine terrain, this is heaven. If you're still building comfort with exposure, consider starting with something like The Tooth before stepping up to this level.
