Why Join the Sierra Club?

Because we need you!

Your voice will be added to those of more than 700,000 of your fellow Americans who are committed to leave our children a living legacy — clean air, clean water, and natural grandeur. The Sierra Club has been instrumental in preserving wilderness, wildlife and nature's most splendid wild places for over 100 years — Yosemite National Park, Grand Canyon National Park, the Florida Everglades and the Sequoia National Monument to name just a few — helping protect over 150 million acres of wilderness and wildlife habitat.
