There's plenty to do on Matagorda, in addition to nature observation. Historical sites range from an 1852 lighthouse to an abandoned air base. About 30 miles of beach, roadway and mowed paths are available for hiking and biking. Surfing, swimming and beachcombing are all popular. Bicycles and surfboards can be brought over on the state ferry.
Anglers come for a wide variety of sportfish, including redfish, trout, flounder and whiting.
There are two campgrounds. At the boat dock is the Army Hole Campground, equipped with toilets, a cold-water shower and other amenities. There is also a 14-bed group barracks and a smaller overflow barracks. The state ferry from Port O'Connor runs Thursday through Sunday. Ferry and camping fees apply as do shuttle fees for private boat owners using the Beach Campground.
