Petaluma, CA Curfew Laws: Park Curfew (2026)

Sonoma County Regional Parks publishes standard operating hours of 7 a.m. to sunset, with parking lots and entry gates closing when the parks close at sunset. Day-use areas do not permit overnight access; staying in a park after it closes at sunset is not allowed. These park rules, including prohibited conduct, are codified in the Sonoma County Code of Ordinances, Chapter 20 (Parks and Recreation), which contains Article III on Personal Conduct (for example, Sec. 20-8 addresses animals). Overnight stays are limited to established campgrounds with required reservations; hike-in and bike-in sites are first-come, first-served, but general overnight camping outside designated campgrounds is prohibited. Other park policies regulate dogs (leashed, six-foot maximum leash, attended at all times), alcohol (prohibited year-round at certain parks such as Larson Park, Healdsburg Veterans Memorial Beach, and Guerneville River Park, and seasonally at others), and special events (Special Use Permit required to serve alcohol where it is otherwise prohibited). Because sunset closing times shift through the year, visitors should plan to exit before dusk. Specific seasonal hours can vary by park, and some sites have separate posted hours, so confirm closing time at the park entrance or on the Regional Parks website before visiting.
