Benton County parks close at posted hours, and staying after closing is treated as trespassing under RCW 9A.52. Riverfront and desert sites set their own schedules, enforced by county staff and the Benton County Sheriff.
Benton County parks and river-access sites along the Yakima and Columbia rivers operate on posted hours set by the county. Entry or use after posted closing is prohibited, with exceptions for registered campers, reserved facilities, and sanctioned after-hours events. Day-use areas, boat launches, and trails may keep separate dawn-to-dusk hours. Once staff or a deputy tells a visitor to leave and they stay, it becomes criminal trespass under RCW 9A.52, enforced by the Benton County Sheriff's Office. The Tri-Cities' many riverfront parks, plus nearby state parks, each post their own separate hours.
Remaining in a county park after posted hours is a trespassing violation, chargeable as criminal trespass under RCW 9A.52 once you are asked to leave and stay. Unauthorized camping carries its own citation.
