The Elbow Cays are uninhabited cays in the Cay Sal Bank, Bahamas. It is the most Western point in the Bahamas. They are part of a reef shelf located at the northwestern end of the bank about 80 km (50 mi) off the Cuban coast and 130 km (80 mi) southeast of Key West, Florida. These cays are an excellent scuba diving spot.
