Angeles Chapter

About Us

On November 1, 1911, 75 Sierra Club members gathered in downtown Los Angeles to sign a petition calling for the creation of a "Southern California Section," the first local chapter in the history of the organization that John Muir founded in San Francisco in 1892.

Today the Sierra Club Angeles Chapter covers Los Angeles and Orange Counties and includes 13 regional groups (organized by geographical area) and 32 outdoors activity sections and committees (organized by interest). Chapter coordination and oversight is provided by an elected volunteer Executive Committee which oversees chapter staff. Hundreds of volunteer leaders work across our region to advance our priorities.

Together, we offer a wide array of activities to engage members and the general public in efforts to explore, enjoy, and protect our shared environment.
