 SPOILER: At the end of the film, Barbossa suggests to his crew that  they go looking for the Fountain of Youth, but is prevented from  doing so since the relevant portion of the map has been stolen. Next  we see Jack Sparrow, in his dinghy, turning the rings of the map to  form a chalice and the location of the Fountain of Youth marked by  an X. The X marks Florida, where ironically, Captain Jack Sparrow  lives to this day at Disney World. Another reason why it marks  Florida is because St. Augustine, Florida (the nations oldest city)  is the host city to what Spanish explorers (specifically Juan Ponce  de Leon) believed to be the Fountain of Youth. Tourists still visit  the site to this day.
