Things to Do in
Petaluma, CA
Early fall settles along the Petaluma River — golden light over the Sonoma hills, harvest season in the air, and a full calendar of festivals, live music, and community gatherings to make the most of it.
September in Petaluma is a gift. The summer heat eases, the hills go amber, and the city’s Victorian storefronts and riverside walkways become the backdrop for one of the most event-packed months of the year. From craft beer on the waterfront to antiques in historic downtown, bluegrass at the Mystic Theatre to a harvest dinner at McEvoy Ranch — this is Petaluma at its most alive.
