The Alps have the Haute Route, the Cascades have the Forbidden Tour. Starting in Boston Basin, we traverse some of the largest glaciers in the Cascades. We circumnavigate Forbidden, Klawatti and Eldorado Peaks crossing 3 passes enjoying several 3-4,000 foot descents along the way. This tour takes you far away from the crowds of Whistler and Chamonix while offering up some of the most rugged terrain in the Lower forty-eight.

By adding an extra day you can add a few more summits and descents such as Klawatti South Face, Eldorado Northeast Face, Dorado Needle and the Torment Couloir.

Our recommended clothing system has four layers.
  • Base layer: manages moisture and wicks perspiration away from your skin. (Polypro, capilene, driclime)
  • Softshell: should be a durable, comfortable, insulating and wind/water resistant layer that breathes well.
  • Hard shell: windproof, waterproof and breathable.  (e.g. Gore-Tex, or similar)
  • Insulating layer: should be down-fill or synthetic-fill and fit over all layers. (e.g. down, primaloft or polarguard)

These four layers are usually sufficient for most people, but if you tend to be colder bring one extra medium-layer that would be ideal for extra warmth around camp, such as a vest. When deciding what to pack, remember to bring enough clothes and accessories to ensure your safety and comfort, while not over-burdening yourself with items you probably won’t use.

You will receive an introductory email with the instructor for your course. We are small company who enjoy working together in the mountains as well as highly skilled professionals who hold current Wilderness First Responder certification and are proficient in technical rescue and evacuation skills. Our guides are dedicated to the world of alpinism, many having first ascents and hold professional certifications with AIARE & AMGA. The AMGA is part of the IFMGA, which is the international body of certified mountain guides.

Tipping is considered standard practice in the guiding industry. Tipping amounts vary – so $15-20 per day per person/per guide is average that works well for the guides without a serious blow to your wallet. Often 10% of the course cost is a good rule-of-thumb. If you feel that the program was exceptional or substandard the tip can reflect that.

We work with Ascent Outdoors who rents full ski and splitboard packages as well as beacons, shovels, and probes here. If you need these plus touring equipment, Quantities are limited so please contact us as soon as possible if you are interested.

You will carry 10-15 pounds, which will include everything on the equipment list.

50% Deposit when you make your reservation. The Balance is payable 90 days out by same credit card.

If you should decide to cancel your trip, BCAG must be notified in writing. Your trip will be cancelled from the date we receive written notice. You will be assessed a cancellation fee according to the following schedule:
90 to 22 days from trip departure – 50% of trip cost
30 days or less – 100% of trip cost

Schedule changes are subject to a $50 fee per person up to 2 weeks out and $100 less then 14 days from the start of the trip and may not be possible. If conditions or circumstances preclude running a scheduled program we reserve the right to make the decision as to whether the program will be canceled, rescheduled, or an alternative provided.

In the rare circumstance where we need to cancel a program you can reschedule without a fee or receive a refund on your deposit. If circumstances arise that force us to cancel a program that is already in progress we reserve the right to decide whether a refund or credit, at a prorated rate, will be issued. We are not responsible for cancellation fees or costs arising from your changed or cancelled flights, lodging, or other arrangements. We strongly recommend obtaining trip cancellation insurance from your travel agent.

BCAG highly encourages the purchasing of trip cancellation and travel insurance on domestic trips and requires it on International trips. Europeans and Canadians use it because travel insurance provides coverage for trip cancellation and interruption, travel delays, loss of baggage and travel documents, baggage delays, medical expenses and emergency assistance.
Several options include Travelex or Travel Guard International at (1-877-248-8992) & for protecting your investment, however there are many companies to choose from and you may wish to do some individual research regarding which policy is right for you.

We often get this question because most people need to know how much total time they need to take off work. Our return to Seattle on the last day may be late so plan you flights for the following day.
