Keyewaydin Island is an 8 mile long barrier island located between Naples and Marco Island, Florida and is part of the pristine Rookery Bay Reserve. Although some lots were sold off and developed in the past, the island has preserved its natural state with many mangroves, birds and native wildlife. Keewaydin is largely undeveloped and offers miles of soft white sandy beaches and is only accessible by boat, with just a handful of single-family residences.
