Explore, enjoy, and protect the planet


  • One-to-Five Start My Journey
In 1892, John Muir and his friends decided something needed to be done to protect our planet, so they started the Sierra Club. 125 years later, we’re continuing to make progress--defending clean air and water, threatened forests, the health of communities, or our planet’s climate. You can celebrate 125 years of exploring, enjoying, and protecting our planet with us!

Here’s how: Be the 1 to start a Team Sierra fundraiser and challenge 5 people to join you.
Plus, get a FREE Team Sierra hat when you raise $100 by June 30.

The progress we’ve made is because of you. We began with 200 members, and today we’ve grown to 3 million environmental champions. It’s incredibly powerful when people come together to work toward shared values. So, be the 1 and challenge your 5 now!
