As you cross over the scenic Rickenbacker Causeway to the island of Key Biscayne, chances are you’ll feel like you’ve arrived in paradise. What was once a coconut plantation is now known for being a low-key tropical oasis, with quaint neighborhoods, palm tree-lined streets, and stellar outdoor activity options. Beaches are a thing, but there are also plenty of boating opportunities, and local eateries famous for their food as well as their idyllic location.
