It's only small the first 2 sites are the best. Valt toilets cleanish it is free tho with 10day limit. No room for rv or trailers. Sweet swimming hole down the creek with some really good fishing too. You can walk up to the falls either on a trail or along the river on the slate rock. Yaak river road is beautiful worth a night or 4 or 6.
The Yaak River campground is a local summertime favorite! Although busy for day-use but locals, the campground can often be quiet in the evening hours. A number of great swimming holes and the waterfall itself make this a great choice! Also, great proximity to trails, beautiful drives, and even some beer on the Yaak River!
