It would be an insult to campgrounds to call this one. it's just a gravel road in the bottomland (right inside the levee in fact), with turnouts where you can pull off and park. Random OHVs roar past well into the night. It is the road to the Little Heart Gun Range.
A very handy spot, right outside St Marks Wildlife Refuge. A great place to spend more time someday.
A really interesting place. The entrance and Visitors Center are five miles off the highway, then it's another five miles to the payoff, the lighthouse and actual Gulf of Mexico. The Visitors Center looks quite deluxe, but both times I have been hurrying to make sunset at the beach, and both times I forgot to return in the morning.
