Sitting ninety miles south of Miami along the Overseas Highway at Mile Marker 61, Duck Key takes two hours to reach by car. Linked by five low bridges over Venetian-style canals, the island is known for direct marina access to Atlantic patch reefs and calm backcountry flats. There are no neon strips or cruise docks here, just saltwater channels and boat slips. Duck Key is worth visiting if you want to fish for yellowtail snapper, paddle open flats, and sleep away from highway bustle.

Duck Key is an orderly enclave of five interconnected islands linked by stone bridges, surrounded by flats and deepwater channels. The day starts with skiffs idling out to the Atlantic and ends with drinks on canal-facing patios. Without commercial boardwalks or tourist shops, the pace is quiet, suited to anglers, boaters, and anyone seeking predictable saltwater calm between Marathon and Islamorada.
Charter a morning half-day boat out to Coffins Patch reef, return by midday for grilled mahi tacos at the marina, and spend the afternoon paddling a kayak through Tom's Harbor Cut. End with grilled snapper and a quiet walk across the Indies Drive bridge. Select 1 Day above to see it.
Day two takes you six miles west to Marathon. Tour the historic railway cottages on Pigeon Key, walk the Old Seven Mile Bridge, and stop at a roadside Grassy Key shack for cold smoked amberjack dip and warm key lime pie before a sunset boat run. Choose 2 Days to expand the plan.
A third day allows an unhurried morning running a skiff into the backcountry flats of Florida Bay to search for tailing bonefish. Spend the late afternoon drifting the canal channels or driving north to Long Key State Park to walk the Golden Orb Trail.
