It is a nice Campground on Sullivan lake run by the U.S. Forest Service.

It has all the amenities you would expect from a campground run by them. It has vault toilets, onsite trash pickup, and water. There is a day use area on the lake with picnic tables, grills, bathrooms and even a boat launch! It boasts 32 campsites, 6 double campsites, 1 group campsite(up to 40 people) all with picnic tables, fire pits, and tent pads. The pricing is as follows:

$20/single site

$40/double site

$75/group site 

$10/Extra vehicle

$5/Day use

Overall This is a nice place with a few small towns close by incase you need supplies. I would check it out if in the area.
