It begins in the marshes south of Melbourne, in Brevard County, flows north, and reaches the Atlantic near Jacksonville, falling less than 30 feet along the way.

Where can you take a boat cruise in Florida?

Two meanings, both answered. For a short trip on the water, the river and spring cruises are the ones with something to look at: Wakulla Springs runs a guided river cruise past alligators and wading birds, Silver Springs in Marion County runs glass-bottom boats, and Myakka River State Park in Sarasota County runs what it calls the largest airboat of its kind.
