The fort is typically open from early or mid May through Columbus Day weekend. DCR Rangers offer guided tours, or you may explore on your own. An information booth just outside the sally port (the main entrance to the fort) posts information about available activities. The island offers a well-stocked snack bar, water fountains, and a large number of composting toilets. There is also a museum located in the old mine storehouse (the red brick building opposite the ferry dock), a number of picnic tables, and a children's play structure. The tops of several of the walls and several of the casemates and magazines beneath them are open to visitors. The dock side of the fort features two Civil War 3-inch rifled guns converted to breechloaders. 10-inch Rodman guns, projectiles from the Endicott era, and two World War II 40 mm Bofors guns are also at the fort. The museum includes a demonstration model of a disappearing gun and a Nike-Ajax missile.
