The Castillo is not fully accessible to persons in wheelchairs

The Castillo de San Marcos was built for ancient warfare, not for public touring. Unfortunately, the need to preserve the historical and architectural integrity of the fortress limits access to some areas.


Free parking is available in the visitor lot for properly identified vehicles.

The Park can provide a wheelchair for use while visiting the fort. Rental wheelchairs and other conveyances are available from a nearby concession.

The parking lot and the fort's lower level, which includes the museum rooms, the theater, the bookstore and the restrooms, are wheelchair accessible.

Most of the Park's pedestrian walkways are paved; however, those within the moat and covered way are sand and crushed shell stone. The Gun Deck Level can only be reached by stairs

Interpretive Services
