Elliott Key campground is located on an island. The only access is by boat. Elliott Key features waterside and partially forested camping areas, picnic tables, and grills. Restrooms with sinks and cold water showers are available. A mile-long loop hiking trail starts near the campground. Another walking trail, the infamous "Spite Highway" runs approximately six miles down the center of the island. At low tide, the depth of the entrance to the marina is approximately 2 1/2 feet.
