Southwest Florida
The science and magic behind the Gulf Coast
Book Direct & SaveFlorida has more coastline than any other state in the contiguous U.S. — nearly 1,350 miles of beaches. But it's not just the quantity. Florida's Gulf Coast beaches are genuinely, scientifically different. Here's why.
Florida's Gulf Coast beaches — including Marco Island — are made of quartz crystal sand that has been tumbled and refined over thousands of years. The result is sand that is powdery soft (doesn't pack hard and clump like Atlantic or Pacific beaches), brilliant white (high quartz content reflects light), and cool to the touch even in summer heat (reflects rather than absorbs sunlight). This is the same sand that makes Siesta Key, Clearwater, and Marco Island repeatedly rank among the best beaches in the world.
The Gulf of Mexico is a large, shallow basin — and shallow water heats up much faster than deep ocean water. Gulf water temperatures on Marco Island range from about 68°F in January to 87°F in August. Compare that to California, where water temperatures rarely exceed 65°F even in summer.
The Gulf of Mexico is largely protected from open ocean swells. The result is gentle, lapping waves rather than pounding surf. Ideal for families with young children, older visitors, and anyone who wants to float or swim without getting knocked over.
Florida beaches are alive in a way most states' beaches simply aren't. Dolphins swim through coastal waterways daily — guests at Riverside Relaxation on Marco Island see them from the private lanai almost every morning. Manatees visit the warm shallow waters regularly. Sea turtles nest on Marco Island beaches every summer. Roseate spoonbills, ospreys, pelicans, and herons are everywhere. And Florida's Gulf Coast produces some of the best shelling in the world.
Florida's Gulf Coast faces west — which means you watch the sun set directly over the water every evening. The warm Gulf atmosphere creates vivid oranges, pinks, and purples. Watching a Gulf sunset from a private waterfront lanai on Marco Island is one of those travel experiences people describe for years.
Marco Island sits at the edge of the 10,000 Islands — one of the largest mangrove estuaries in North America and part of the Everglades ecosystem. Nowhere else in the continental U.S. can you swim in warm Gulf water in the morning and kayak through a primeval mangrove jungle in the afternoon.
