The Overseas Highway will bring you all the way through the Florida Keys, starting from the tip of mainland Florida near Miami traveling 113 miles crossing over 40 trans-ocean bridges as it makes its way to Key West, the southernmost point. You’ll have breathtaking scenery in every direction, with one of the best stretches being Seven Mile Bridge, the longest bridge in the Keys, which traverses seven miles through dazzling blue-green waters. Plan to make multiple stops to take advantage of this snorkeler’s and diver’s paradise. John Pennekamp Coral Reef State Park in Key Largo is a must, with vibrant coral reefs, colorful tropical fish, sea turtles and shipwrecks.
