Part of the National Seashore, it is accessable by private boat or tour boat. Right off the pier is the fort, which is well worth a quick look. Most people head across the boardwalk (@ 1/2 mile long) over to the beach. Umbrellas and chairs are rented there. Limited food choices at the snack bar, enough to keep you fed for the hours you are there. Restroom facilities are adequate but you may need to wait as there are only 2 showers in each side. Searching for shells is great and you can walk all the way around the island (6 Miles) if you have the energy. Summer is really hot and there is little to no shade except for the fort, pavillions and the umbrellas for rent. Can fish with a state license and many people seem to enjoy the variety of fish they can catch. Lots of people boogie boarding and using floats. Lifeguards are there only part of the season, so you have to watch out for your family! Disappointing there was no one to provide tours of the fort, only brochures available.
All in all a great place to visit but you need to be somewhat prepared to take care of yourself.
