Alternatives are Alexander Springs and Juniper Springs. I think Salt Springs has the largest CG but I'm not sure of that. There are distributed (boondocking) sites in the forest but beware of the 'sugar sand' which can be a problem if you don't have 4WD. For the developed CG make your reservation right away, it could be too late but hopefully not. There are many private CG too but I'm not familiar with them.
As for what is there to do, most activities will center on the three big springs. Swimming, canoeing and kayaking. Alexander is popular for newbie Scuba diving and you can snorkel in all three springs. Not too far away in Ocala you can visit Silver River State Park and Silver Springs SP. The state has taken Silver Springs back from the private contractor who was running it. They have a glass bottom boat ride.
There are many other state parks, most with water: either springs or rivers within easy driving distance. The Atlantic beaches aren't that far away either. St Augustine is good for day trips too.
Alexander springs has always been our favorite.
