The Sierra Club's members are 700,000 of your friends and neighbors. Inspired by nature, we work together to protect our communities and the planet. The Club is America's oldest, largest and most influential grassroots environmental organization.

You may become a member of the Sierra Club by filling out the on-line Sierra Club Membership form. In joining the Sierra club not only do you receive the award-winning Sierra Club magazine, which is filled with spectacular nature photography and in-depth reporting on the hottest environmental issues, but you'll enjoy other countless benefits.

NOTE: Sierra Club membership is not required for participation in GLS events, but it is strongly encouraged. To receive the GLS Section newsletter Tracks you will need to subscribe to it separately.
