Hideaway Beach is a beautiful white sugar-sand, crescent-shaped beach on Marco Island's northwest Gulf of Mexico shore. Land access is only through the private club or walking from Tigertail Beach at low tide or docking a boat up to the mean high-tide mark. There is a large sand shoal formed off Tigertail and Hideaway beaches called Sand Dollar Island. It is a huge stop for migrating bird life on the Atlantic flyway. One can also anchor a boat at Sand Dollar Island to observe the wildlife but it is not advisable to walk across the lagoon to Tigertail or Hideaway beaches because strong tides come in.
