The barrier island of Casey Key is one of Florida's Gulf Coast hidden gems. This community is located just south of Siesta Key and just north of Venice Florida. Almost all of the properties on the Island are single-family homes. Generally, most of the homes for sale are waterfront properties. The homes on the western side are beachfront homes on the Gulf of Mexico. The homes on the eastern side face the bay. If you want to get away from the crowds and enjoy waterfront living at its best, a home in Casey Key is a great option.
