You may do one of the following:
- Sign up online, using the "Book It" button at the top of the trip brochure, and follow the instructions on our secure and easy online reservation system.
- Call 415-977-5522 (M-F 8:30 am-5 pm PST) to place a credit card deposit. Please have the trip number and your credit card information and membership number handy.
- Fill out a reservation form and include all people who want to be considered as part of that trip party (if you're signing up for more than one trip, please make copies of the reservation form). The first person on the reservation form is considered the primary applicant and will be the only party member to receive reservation information, brochures, bills, and forms. Please include on a separate sheet of paper any addresses that may be different from the primary applicant's address. Mail or fax your completed reservation to the address/fax number listed on the form.
If you are not currently a Sierra Club member, you may apply for membership when you sign up for the trip.
For all credit card deposits (Visa or MasterCard only), please be sure to include: your credit card number, its expiration date, and your signature, in addition to the above information. **Credit card applications submitted less than 90 days before the trip departure date will be debited the full trip fee. Please fill in the full amount on your application.**
