Stayed here in early May. Nicely spaced sites and while entirely acceptable (at least for me) the pads are showing their age. Stayed in Summit campground with no hook-ups. Very peaceful, especially since two nights I was the only person in that section. Not a lot of hiking but what there is is beautiful, and a bit challenging with some rocky areas. The dam is the remains from a mining operation that ran from 1877 to 1946. I think you could walk across it in low water in the past but it has been breached (I think intentionally) to open the river up for kayaking. The only negative was no dump station, so plan accordingly.

We really enjoyed our stay here. There are 4 different loops: one right on the river with electric and water and 3 loops on the other side of the river with no hook-ups just vault toilets. We stayed at the Spring Branch loop which had large, nicely spaced sites. But only a couple of the sites where level. There are trails leading down to the river and along the river. We didn't have any cell service at the Spring Branch loop but further up the hill we could get a couple of bars of Verizon. Only a handful of other campers on a Friday in April.

Looked lovely…. Unfortunately, even though I could find no mention of a closing season on the NF page AND it said the area was open, it was closed. We were bummed to have wasted a half an hour trying to find it and then having to continue on.
