5. Fort Matanzas, Fla.( Jessica Whittle via Flickr )
Matanzas, Spanish for "slaughters" or "killings," is an appropriate name for the river on the east coast of Florida, where the Spanish massacred French soldiers in 1565 during efforts to colonize the area.
Fort Matanzas is 15 miles south of St. Augustine, about midway between Jacksonville and Daytona Beach. A ferry ride takes visitors to the fort, where they can explore a boardwalk forest trail, fishing on the riverbank and walk along the beach. The best time to travel to Fort Matanzas is in the temperate fall and spring.
Visitors in 2009: 793,253
