Cape Sable is the southernmost point of the United States mainland and mainland Florida. It is located in southwestern Florida, in Monroe County, and is part of the Everglades National Park.
The cape is a peninsula issuing from the southeastern part of the Florida mainland, running west and curving around to the north, reaching Ponce de Leon Bay, at the mouth of the Shark River. It forms the southern and western margins of Whitewater Bay.
There are three prominent points on the cape, East Cape, which is the actual southernmost point of the Florida and United States mainland and the location of Lake Ingraham, the southernmost lake in the United States of America, Middle Cape, also known as Palm Point, and Northwest Cape. The cape has many lakes and beaches.
