$5 for walk up site. and if you go off on any trail stay 500 ft from a road 100 ft from trail or natural water river/lake its free you dont need to pay to back pack in Oregon forests, but be careful of this area because a lot of people own property surrounding the vacation home you pass so better to go down river. Also many people "back pack" just out side the camp ground and use the day use areas during the day so don't expect to be the only one with this plan.
$20/night for a pull-in site.
