Grass Valley, CA Curfew Laws: Park Curfew (2026)

Park hours in unincorporated Nevada County are largely governed not by a county-wide ordinance but by the individual special districts and state agencies that operate the parks. Nevada County has multiple independent recreation and park districts, including the Western Gateway Recreation & Park District (Western Gateway Park, Penn Valley), Truckee-Donner Recreation & Park District (which manages Truckee River Regional Park, Donner Lake parks, and others), the Bear River Recreation & Park District, and the Oak Tree Recreation & Park District. These are special districts that operate separately from direct County management and set their own park rules and operating hours; for example, Western Gateway Park has been reported as open daily roughly 8:00 a.m. to 6:00 p.m., and county parks are commonly described as open daily from sunrise to sunset with dogs required to be leashed. State parks within the county, such as Malakoff Diggins State Historic Park and South Yuba River State Park, are open daily sunrise to sunset and are subject to California State Parks rules rather than county ordinance. Because the operating jurisdiction differs from park to park, there is no uniform county park 'curfew'; visitors should check the posted hours and rules for the specific park or contact the managing district or California State Parks. If a county-administered facility imposes specific hours, those would be set through the County Code or facility regulations rather than a general parks-curfew chapter.
