Lumen Nature Retreat

I discovered this small family-run campground while driving to another one and my curiosity was piqued, so I had to check it out. After a friendly welcome, I was allowed to explore. They offer wooded campsites, some of them along a a brook and others near a pond; There's no boating or swimming in the private pond because of steep sides, but it's stocked and license-free fishing is possible for trout and catfish. The brook runs into the Pemi river. There is also a swimming hole, but I didn't get a chance to explore that. 

The 31 sites vary in size, but are reasonably level, no hookups. A clean, bright bathhouse provides toilets and coin-operated showers; a dumpstation is also available for RVs.

The office is also a store with minimal supplies and firewood. Let them know when you plan to arrive and call if you'll be late to hold your site. They're open full-time Memorial Day to Labor Day, and then weekends only through Columbus Day.
