East Fork campground has 6 campsites right on the confluence of the East and South forks of the Salmon River. There is no water and no garbage services here, but there is a vault toilet available.
Nice little campground right next to a pretty river. When I stayed I was the only one at the campground. The sites are near the road but it seemed to have light usage and I never heard cars in the night.
No running water (unless you filter from the river) and no trash services, just a pit toilet.
This campground is a great place to stay before heading into the Trinity Alps. A 20 minute drive on a dirt road leads to the China Gultch Trailhead, a popular trail leading to Grizzly Lake.
I would definitely recommend this site to anyone headed into the Alps.
