I've stayed at Energy several times, and thought this would be a good time to update the review. Energy Lake is in Land Between the Lakes (LBL) and is ideal for nature viewing, hiking, swimming and hanging out by the camp fire. There are four loops, with A being the newest camping loop, B has been converted to all single room cabins, C & D remain unchanged, but are well kept and maintained. The staff at this campground is AMAZING, and very knowledgeable about LBL and the two small towns on either side of LBL (Aurora and Cadiz). The lake itself is man made, and motorized water craft are not permitted being there is a nature sanctuary in the back creek end of the lake, which makes for great swimming, and my favorite lake to kayak through with all three dogs on board. There are multiple access points to the lake with roads leading to the lake from both sides for launching, or you can paddle across.  There are NO WATER or SEWER hookups at any of the sites, and the sites in A & B are compacted gravel, designed for either RV or tent, loop D's sites are all paved and preferred by RV's.
