Nice park but dated campground
A decent state park overall with neat trails to go on and a nice Civilian Conservation Corps museum. It's Florida's first state park, opened in 1935, and the facilities in the campground are definitely showing their age.
The campsites vary greatly in size and shape, so getting a spot may be trickier if you have a larger rig not just due to the site but also access to it. Most sites are right on top of one another so there zero privacy.
The bathrooms are all quite outdated and in disrepair although the team tries to keep them clean. (A more modern bathroom building exists, but as of March 2022, it's closed for repairs.) The water connections and electric hookups at each site are old and many are in need of replacement soon.
The trails are nice, all of them are quite short but there are enough to make a day of it as you travel from trailhead to trailhead. You could walk the whole thing if you're up for it, but it makes for a nice bike ride, too, since there are bike racks at each trailhead.
Also, consider taking the tram tour since you get to see parts of the park that are restricted to the public. When we took it, we saw a lot of wildlife, including alligators, turtles, birds, and deer.
Overall, I'd like to give this park a higher rating, but the aging infrastructure of the campground really needs to be addressed. So maybe 4 stars for the park as day use, but only 3 stars if you're staying there.
