Napa County's parks and open space lands are operated primarily by the Napa County Regional Park and Open Space District (independent special district) and the California State Parks system (Bothe-Napa Valley, Robert Louis Stevenson). Most regional parks and open-space preserves are open dawn to dusk - typical posted hours run from 8 a.m. to sunset. After-hours presence is treated as trespass or a violation of posted regulations, and the County's Chapter 9.08 juvenile curfew separately covers minors in parks during nighttime hours.
