Port Royal, on the south part of the peninsula that also includes Old Naples and Aqualane Shores, is the premier boating community in Naples. Of the 500 or so single-family houses in the community, most have back-yard docks on Naples Bay or one of the deep-water feeder canals, a few of which can handle boats up to 100 feet in length. On the western side of the neighborhood, beachfront mansions line the Gulf of Mexico. Some homes were built when the community was developed in the 1950s and 1960s, but most have been reconstructed or torn down to make way for new estates. Boaters can get to the Gulf of Mexico within minutes via Gordon Pass. Marine facilities are available at the City Dock in Old Naples. Residents on almost all the streets in Port Royal are eligible for membership in the Port Royal Club, which is directly on the beach. It has nine tennis courts, dining facilities and an Olympic-sized swimming pool. The club serves as the Port Royal community center, with a wide variety of social activities.
