DNR managed campsite right off highway 101 about 20 minutes west of Sol Duc-Hot Springs Road. It has 9 campsites, first come first served (free with an Adventure Pass) with picnic tables, fire rings and a couple of fairly gross vault toilets. The sites can accommodate medium (~30ft) RVs but there aren’t any hookups. Primitive camping at it’s best. I stayed in site #8 which overlooks the Sol Duc River. There is a good bit of road noise being this close to the highway, but as a cheap spot to overnight close to Olympic NP it’s super convenient.
