Park hours in Washington County are governed by multiple agencies. Washington County Parks (Hagg Lake, Scoggins Valley Park) post hours varying by season — typically 7 AM to sunset, extended for boat launches during fishing season. THPRD — the Tualatin Hills Park & Recreation District serving 250,000 residents in Beaverton and surrounding unincorporated areas — operates under Oregon special district law (ORS 266); THPRD parks and natural areas open dawn to dusk with longer hours at lit sports fields and Conestoga/Aquatic/Recreation facilities. Metro regional parks in the county (Cooper Mountain Nature Park, Graham Oaks, Tualatin River NWR in Sherwood) follow Metro Code Chapter 5.04: generally sunrise to sunset for natural areas, longer for developed parks. City parks: Beaverton (BC 6.02, typically 5 AM-10 PM), Hillsboro (HMC 10.20, dawn-dusk or 10 PM), Tigard, Tualatin, and Sherwood all have posted schedules. After-hours presence is a Class B misdemeanor (ORS 164.245 trespass in the second degree) on public land OR a park-rule violation under the governing agency's code. Camping in non-designated areas prohibited. Off-leash dog areas (Hondo at Tualatin Hills Nature Park, others) have specific hours.
After-hours trespass: $50-$500 citation under agency code; criminal trespass II (ORS 164.245) up to $1,250/30 days. Unauthorized camping: $100-$500. Vandalism: separate criminal charges.
