Ka Lae is also known as South Point, and is located on the tip of the Hawaiian mainland. It is geographically considered the southernmost point of the United States. The area is known for strong ocean currents and high winds, making it an ideal spot for wind farms. Legend has it that Ka Lae is where the Polynesians first landed, and there are several archaeological sites that lend credence to that theory. Naalehu is the closest town, and from there Ka Lae is accessible via South Point Road. Visitors should be advised that the last five miles of South Point Road are steep and rough, and use of a four-wheel drive vehicle is recommended when visiting the area.
