This is a large parcel of land owned and operated by the Army Corps of Engineers. Also known as Bob Woodruff Park, located right on the Alabama River, there's access to swimming, hiking, fishing and of course boating. However, you may want to visit one of the surrounding parks for well maintained and improved launching areas (Prairie Creek, Gunter Hill, etc.)
There isn't camping located in the immediate vicinity, however you can camp just down the road at either the Prairie Creek Park Campgrounds or back toward Montgomery a bit at Gunter Hill Park (also run my the Army Corps of Engineers).
If the fish aren't biting, you're close enough to the city of Montgomery to explore the area. Or head to Selma and learn about the Selma to Montgomery March!
