We all need nature

The Sierra Club began as a few people who found the magnificent wilderness areas they loved threatened by deforestation. They decided to show others the beauty of the wilderness in order to stop its destruction.

Today, Sierra Club members embody our "Explore, enjoy, and protect the planet" principles through trips, outings, meetings, and other events.

The Sierra Club offers hundreds of fun and affordable trips spanning the United States and across the globe. Trips include options for all ages and abilities. Find out more about Sierra Club outing destinations and activities. 

The 14 volunteer groups that make up the Sierra Club Illinois Chapter sponsor local outings, meetings, and other events. These outings and events are open to all Sierra Club members. Check the Sierra Club Illinois calendar for information on events near you — and throughout Illinois.
