Rainbow Springs State Park

Steve’s take

Crystal clear springs where the water is 72 degrees year-round. The kids can swim in water so clear you can see a quarter on the bottom from twenty feet away. It's about 20 minutes off I-75 and it's the kind of Florida that existed before theme parks — the real deal. If you've got time and swimsuits packed where you can reach them, this is a Griswold family top-five stop.
