There are several spots on both the main Chetco River (North Fork) and the smaller south fork that meanders into it.
There's one pit toilet near a circle of 3-4 sites on the rivers. This is pretty wild camping, no amenities, but quiet camping. Probably best to use a car or truck with a little clearance but most cars should work unless it's wet and muddy.
We saw a beaver swim up the river. We also saw a small herd of cows that rolled through. There's private land nearby so we assume they are escapees or allowed to roam.
The spot is officially called South Forks Campground and there's a sign there once you go down off the main road a bit.
