Join the Club!

The Sierra Club is the largest and oldest grass-roots environmental organization in the world. More than 700,000 people like you, who care about our quality of life, are Sierra Club members.

The Angeles Chapter, which includes Los Angeles and Orange Counties, is the largest Chapter in the nation, and the most influential environmental organization in southern California.

We invite you to join us! We have over 4,000 hikes and outings every year, and we are working hard to protect thousands of acres of open space in Orange and Los Angeles Counties.
