There are normal drive in sites and primitive hike-in sites.
Hiked in the mile or so to the primitive sites -- pack everything you need in. HELLA skeeters in the woods, bring high DEET spray. We went after it had rained and about a quarter of the trail was basically a mudpit. We were the only ones out there, which was great!
Canoe or kayak down the river is a must do! Gators, turtles, lots of birds and all downstream so pretty lowkey paddle.
