Lake Julia is the largest lake in DuPont Forest, covering 100 acres. Paddling is allowed but the lake is not accessible by vehicle, so visitors need to portage in their kayak, canoe, or paddle board. Camping is prohibited, but fishing by advance permit is encouraged. The lake has largemouth bass, bluegill, redbreast and redear sunfish, bullheads, and black crappy. The large lake is a beautiful view from several of DuPont Forest's southernmost hiking, horseback and mountain bike trails.
