What we’re about

The mission of the Idaho Chapter Sierra Club is simple: to explore, enjoy, and protect the planet. Our outings and events are free and open to members and non-members alike.

The Idaho Sierra Club is a member-supported non-profit organization working to promote the conservation of Idaho's natural environment and climate by influencing public policy decisions through grassroots involvement.

​The Sierra Club's members and supporters are more than 3.5 million of your friends and neighbors across the country. We are America's oldest, largest and most influential grassroots conservation organization.
