Bahia Honda State Park
Between its gorgeous beaches and dazzling sunsets, Bahia Honda State Park offers all of what the Florida Keys are known for in one, 500-acre park. But don't expect to just lounge on the beach all day (no matter how tempting it might be). It would be a shame to visit and miss out on the many activities on offer, whether it's an afternoon of fishing from the shore, some early-morning bird-watching (an onsite Sand and Sea Nature Center will give you the lowdown on the local plant and animal life), or a snorkeling tour from Looe Key National Marine Sanctuary. A campsite and rental cabins make it a wonderful overnight excursion.
