San Miguel was a large area of land on a mysterious island, named for a Spanish fort that was built there. Consisting of jungles and a river, Fort San Miguel was most notably used during the quest for the Fountain of Youth by the Spaniard's crew, who made camp within the abandoned fort. Hector Barbossa, now a privateer, and Jack Sparrow would infiltrate the camp in their attempt to steal the Chalices of Cartagena.
