bflo4 - I used to live near Edisto, and I cabin camped there in April 2006.
Campground Review
Edisto Beach State Park is an amazing place, especially for families with younger children. We stayed in one of the cabins on a dirt road along a saltwater marsh. It is a lovely quiet spot. The cabins even have their own fishing/crabbing dock. The beach is only a mile or so away, and there are camping sites, though no cabins, just steps from the beach. The beach is famous for its shells and for the dolphins playing in the surf. There is a grocery store just outside the state park entrance, and while the store has just about anything you could need, the prices are pricey. The island is relatively undeveloped. There are lots of beautiful beach houses, not too many condos, and I don't think a single hotel. My kids, ages 5 and 7, had the time of their lives.
