Oʻahu-wide camping rules apply: no camping statewide on Oʻahu Wednesday or Thursday nights, permits up to 30 days in advance. Activities: Hiking, Sightseeing. CLOSED (including the ʻAiea Loop Trail) as of the August 24, 2026 update on DLNR's live Important Park Notices page - repairs to HECO power line infrastructure following Hurricane Lala/Tropical Storm Moke.

Hawaii State Park campgrounds are not set up for camping in vehicles (campers, vans, trailers); sleeping in vehicles in campground parking lots is not allowed statewide, and there are no electric/water hookup sites anywhere in the system (dlnr.hawaii.gov, confirmed live). Pets/animals are NOT allowed - confirmed via this park's own DLNR record ("No Animals/Pets" listed explicitly) and Hawaii's statewide Administrative Rules ("not allowed in... campgrounds"). Reservable (permit-based, not a specific numbered site) through Hawaii DLNR Division of State Parks' own reservation system at explore.ehawaii.gov (migrated from the legacy camping.ehawaii.gov system statewide as of February 1, 2026; login required to book).
