What the brochures promised, the island delivered: a six-mile crescent of sugar-white sand, among the widest beaches in Florida, with shelling good enough to draw collectors from around the world. Marco is the largest of the Ten Thousand Islands — the maze of mangrove keys where the Gulf meets the Everglades — and the gateway to all of it: boat trips out through the islands, dolphins and roseate spoonbills, and the warm, shallow, almost-waveless water that makes the place feel like a long, lazy float.
That mix is the modern island: ancient shell mounds under quiet streets, a Calusa cat in the museum, a six-mile beach, and a working channel out to the wild Ten Thousand Islands. The development came with a cost the island still reckons with — the dredged mangroves, the lost wetland — but it also kept Marco’s deep history visible, in the preserves at Otter Mound and Caxambas and the museum that holds the Cat. Few beach towns can show you a thousand years and a planned grid in the same afternoon.
