The Sonoma Group is part of the Redwood Chapter, and is made up of Sierra Club members who live in Sonoma County. The Sierra Club is a grass­roots, volunteer-­led organization. We invite you to find out more about our local activities and how you can be involved.

The Sonoma Group meets on the first Monday of every month at the Environmental Center, located at 55A Ridgway in Santa Rosa.

  • Conservation & subcommittee meetings: 5:00pm to 6:30pm
  • Group executive committee meeting: 6:30pm to 8:00pm.

Join us on a Redwood Chapter outing! Outings are free and open to the public.
