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.
