Call them and see. If you are disabled. Or a senior, the rates are less.
I agree with everyone else you need to call and check. We stayed in the Primitive campsite on the marsh and it was only $25 a night.
Beach front and off the beach are two different prices...good luck with the beach front if you don't already have a reservation. Look at Edisto Island State Park website, it has a map of the campsites, availability, and cost based upon the site. There is a 2 night minimum stay, but being that you are looking at a 4 day stay,that doesn't effect you. Good luck and enjoy
It varies based on season, day of the week, site location, etc.
