America's first undersea park meets easy reef days and legendary wrecks
Overview
Key Largo is the gateway to the Florida Keys reef tract: shallow coral gardens, iconic statues, and big wrecks that start a short boat ride from shore. The centerpiece is John Pennekamp Coral Reef State Park, the first undersea park in the United States, sitting beside the protected waters of Florida Keys National Marine Sanctuary. Most diving is straightforward two-tank boat trips in Hawk Channel, with reefs in 6 m to 18 m and advanced wreck options that drop to around 40 m. On the surface, the Overseas Highway keeps everything simple: fly into Miami, drive south, then choose between sunrise reef trips, mangrove kayaking, and sunset drinks over Florida Bay.
Key Largo's reefs sit inside a long-running protection network (state park plus national marine sanctuary) with mooring buoys designed to prevent anchor damage.
Do your first Keys dives on shallow reefs, then step up to famous deep wrecks like the USS Spiegel Grove when conditions and training line up.
Fly into Miami or Fort Lauderdale, drive one road south, and choose from multiple daily dive and snorkel departures.
