WHAT'S HAPPENING

  • Sierra Club Outdoors reaches across economic lines, cultures, and communities, to engage everyone -- including military and youth -- to explore and enjoy the natural world.
  • 2016 trips are here. We've got 300+ ideas for you.
  • It used to be that electric vehicles were prohibitively expensive for most people. Not anymore.
  • It’s time that we keep the coal in the ground and use our public lands to reflect what’s best for our climate and communities.
  • Sign up with Arcadia Power today and they'll send the Sierra Club a donation -- plus you'll receive 4 free LEDs.
  • GO LOCAL
