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.
When Ponce de León’s Spanish reached this coast in the early 1500s, they named the island La Isla de San Marco and met the Calusa, who fought them off; by the 1700s, war and disease had emptied the chiefdom. Centuries later the pioneers came. William T. Collier founded the village of Marco in 1870, and his son, Capt. Bill Collier, opened the Olde Marco Inn in 1896 — still serving guests today. For decades the island ran on clams and oysters, canned at Caxambas Pass and shipped north.
Why People Visit Marco Island
Marco Island rewards visitors who want wide white sand, warm shallow water, and shells underfoot, with a rare depth of history close by. Add the boat trips into the Ten Thousand Islands and the year-round Gulf sun, and the case makes itself.
