Wonderful, very popular county park. You can view/print out both a park map and campground diagram from the Pinellas County.org/parks website.
Something to be aware of on any beautiful-weather weekend: hundreds of day-visitor local residents could arrive at the park in the mornings, causing a backlog sometimes at the Entrance Station payment gate which is just past the campground. You've already paid as part of your fee, but might be stuck behind the line to get to the beaches, fort, museum, etc.
On weekdays, we find the park's attractions very free of crowds. Enjoy!
