Welcome to the Sierra Club Rocky Mountain Chapter

The Sierra Club's members and supporters are more than 2.4 million of your friends and neighbors across the country; more than 50,000 here in Colorado. Inspired by nature, we work together to protect our communities and the planet. The Sierra Club is America's oldest, largest and most influential grassroots environmental organization.  Our mission is to explore, enjoy, and protect the planet.

The Sierra Club Rocky Mountain Chapter works at the state level, and is also comprised of 10 local groups who focus their work at the municipal and county levels. Explore this website to learn more about what we're doing, where we're headed, and how you can participate. We're involved in everything from hiking to environmental education and conservation - join in and help us protect the air, land, water and wildlife throughout this beautiful state!

We hope you enjoy the new website we've worked hard to create for you!  Please be aware that our website is undergoing transition right now, but if you find a broken link, or think of something for which our website isn't meeting your needs, please let us know.

Make us successful in reaching our mission!

Our mission to enlist humanity to explore, enjoy, and protect the planet, right here in Colorado is as successful as the funds we have to expand to meet that mission.  Please consider joining hundreds of other Coloradans to contribute to our success.  Our goal is to raise $10,000 in tax-deductible contributions via Colorado Gives through the end of December 31st, and as of 12/15, we only have $1,357 to go!

Choose us as your favorite nonprofit fighting for you to protect Colorado. Check out the details on the Colorado Gives Day website:
