The route involves a 4 hour hike to camp, a couple hour climb to the West ridge notch, and then 8 pitches of 5th class climbing up to 5.6 on the West Ridge itself. The best sections of the climb are on the ridge crest itself, and the entire route features impressive views down the North side of Forbidden to lonely Moraine Lake, as well as the spectacular North Face of Johannesberg Peak, the Quien Sabe Glacier on Sahale Peak, and other peaks in the Cascade Pass area.
Of the three ridges we guide on Forbidden Peak, the East Ridge offers the most sustained rock climbing. The climb starts with a several hour approach up the ridges and gullies on the east side of the Unnamed Glacier (oddly its name) below Forbidden Peak, and eventually spits you out near the base of the climb on the East Ridge itself. 6-8 pitches of rock up to 5.8 climb along the ridge crest and traverse both the south and north sides of the ridge bypassing several gendarmes and featuring the same magnificent views seen on the West Ridge. This route is usually done as part of a longer stay in Boston Basin. For the descent we use either the West Ridge or the East Ledges descent.
The North Ridge is a climb that has it all, a tricky approach over loose Sharkfin Col, a glacier traverse on the massive Boston Glacier ending at the North Ridge, a wild pitch of steep dirt to gain the ridge, and finally 8 pitches of snow or ice up to 50° followed by an thrilling and exposed climb up the low 5th class terrain of the upper North Ridge. The route leads directly to the summit pyramid. This climb is always done in at least three days, with most groups bivouacking at the base of the North Ridge on the first night and then reaching Boston Basin on the second night and the trailhead on the third day.
Sits in the middle of the famous Boston Basin. The South East Ridge makes for the perfect introductory alpine rock climb or as an addition to one of the other classic climbs in the area. The climb has a good combination of glacier climbing, steep snow, and moderate rock, enabling the climber to put to use many of the skills needed to be a well-rounded Alpinist.

In addition to our Pacific Northwest climbs we offer international climbing & trekking expeditions through Mountain Gurus. The Ecuador Volcanoes, Elbrus in Russia and the Mexican Volcanoes are all really good next steps for those seeking to climb higher peaks and gain altitude experience internationally.

Personal Health and First Aid
Previous mountaineering experience is not required on most Northwest trips. Our guides will teach you the basic snow and glacier travel skills necessary to make a safe and successful climb. Although above average physical conditioning is required for most mountain climbs in the Cascades. Prior hiking, backpacking or climbing experience is very beneficial. High altitude experience is not required.
Most trips in the Pacific Northwest are rated as strenuous and we cannot over emphasize the importance of conditioning. By getting your heart, lungs, and legs in top physical condition, you can focus on learning, while being able to enjoy the high mountain environment. It is recommended that you have some hiking and backpacking (camping) experience prior to this trip. All participants are required to carry a share of the group food and equipment which includes tents, stoves, pickets, ropes. Be prepared to carry a 40 to 60 lbs backpack to high camp depending on the climb or course you choose.
The mountains of the Cascades Range are physically demanding and your ability to enjoy this adventure depends on your overall health and fitness.
It is often stated. The best training for mountain climbing is hiking, backpacking or climbing with considerable elevation gain (2000 vertical feet or more). Few other fitness activities truly replicate the physical demands of climbing steep mountains with a backpack.
We suggest you begin your training program at least four months prior to departure depending on your current conditioning. Walking up steep hills and stair climbing are both excellent ways to condition your lower body. Begin slowly, without the weight of a pack, eventually adding weight as you increase your training pace. In order to condition yourself to carry the weight, it will be important to take long hikes (4-6 hours) with a weighted pack at least one or two times a week. The best training for mountaineering is to carry a loaded pack up and down hills or small mountains. Hike uphill without breaks for at least an hour at a time when possible. Then break 10-15 minutes at the most and then continue hiking uphill for at least another hour. Do this as much and as often as you can. This is certainly not the only way to train but is probably one of the best ways to train for climbing big mountains. Don’t worry about your pace, this will increase over time, instead hike uphill slower if needed without taking as many breaks. Work at maintaining an even respiratory rate.
Unfortunately, many of you don’t live near good hills or mountains so then you will need to find another activity that will help increase your endurance. Supplement this with running, cycling, swimming, cross-fit sports, weight training, etc. for additional aerobic conditioning your heart and lungs. Any time spent at altitude will also prove beneficial. Remember mountain climbing (unlike running) is an activity where you slowly climb uphill over long periods of time while carrying heavy to a moderate amount of weight.
