This small community supports local organizations for almost any interest. They hold annual events to share their passion and you can find those events listed on the calendar.
You can practice your interests here as well, such as photography, painting, quilting, knitting, and beading. If your passion is history, books by local authors are readily available in local bookstores.
If you are not finding what you need, ask at the visitor center, 115 Valley View Way, just off Highway 49, at Sutter Hill Transit Center. They will point you in the right direction.
