Encompassing most of Cumberland Island, the largest barrier island in Georgia, the Cumberland Island National Seashore boasts more than 17 miles of pristine beaches. The island itself can be reached by taking a ferry from the mainland, but all of the campgrounds are walk-in only. The most popular campground is the Sea Camp Campground, which is the closest to the ferry dock and features amenities like flush toilets, drinking water, and fire rings, but the Stafford Beach Campground is also a good choice if you don't mind hiking 3.5 miles to get there. There are also several wilderness campgrounds with no amenities.
