Silver Springs State Park

Steve’s take

Glass-bottom boat rides over water so clear you can see fish, turtles, and the occasional alligator lounging on the bottom like he's at a spa. Silver Springs is old Florida — this is where they filmed six Tarzan movies and parts of The Creature from the Black Lagoon. Your kids don't care about that, but they will absolutely care about seeing an alligator through a glass boat. About 15 minutes off I-75.
