FREE Events in Marin (August 2025)

Every month I check a bunch of websites to see what’s happening in Marin, and it’s amazing to me how much you can do around here for free! If you’re interested in guided hikes, outdoor events, music, theater, lectures and book clubs, you’ll find all that listed below.

For this list, I’ve chosen events that are ideal for an adult on their own. Also, the list excludes events that are free but encourage you to purchase something (like farmers’ markets, authors talking about new releases, or live music at a restaurant).
