Willamette Mission State Park

Willamette Mission State Park is an Oregon State Park with 5 reservable group/horse sites (Beaver Island Group Camp for up to 75 tent campers, a 4-site horse camp) plus a first-come-first-served hiker/biker camp (site count undocumented); no showers.

Oregon State Parks does not publish one single statewide rate card; per its own FAQ (rates effective May 1, 2026): top rate at the 29 busiest parks is $29/night for tent sites and $52/night for full-hookup RV sites (May 1-Sep 30); cabins/yurts range $72-$129/night; overnight parking, overflow and primitive camping is at least $15/night; hiker/biker sites are $7-$10/person/night. A $10 extra-vehicle fee may apply; a $10 RV dump-station fee applies at select parks (free for registered campers who are current on lodging); non-camper showers are $5 at select parks. Pets must be physically restrained (held, held by the collar, or on a leash no longer than 6 feet), per Oregon State Parks' statewide pet policy - some trails within parks may prohibit pets entirely (source: stateparks.oregon.gov FAQ).
