Exclusive, secure, and breathtakingly scenic, the private barrier island of Casey Key offers its wealthy residents an unparalleled blend of tropical grandeur and low-key privacy along its eight-mile-long expanse, just off the quiet mainland town of Nokomis. This narrow island is one of Sarasota's hidden gems-an isolated enclave nestled between the Gulf of Mexico to its west and Sarasota Bay to its east. With beachfront properties, magnificent gated estates, contemporary coastal homes, and grand waterfront mansions, this pristine barrier island has some of the best beaches in Sarasota County.
