Chicago Group

We are activists, environmentalists and explorers.

Founded by John Muir in 1892, the Sierra Club works to protect communities, conserve wild places, and explore nature. The Chicago Sierra Club is 7,500 members strong. Our territory stretches south from the Lake County line to the Indiana border, west to part of La Grange, and north through Niles and Skokie. We are active in environmental issues, electoral campaigns, and social events. 

Check our Calendar below for information on some of our upcoming events. Visit the Volunteer tab above to find information on teams and leaders who can help you get involved, and follow us on Facebook and Twitter to stay up to date.
