Mount Desert Rock Light is located approximately 20 miles south of Mount Desert Island in the town of Frenchboro. This lighthouse is not open to the public and is best viewed by boat cruises offered in the area. In 1998, the light and island became the property of the College of the Atlantic and is now used as a whale research station. This light station is considered to be one of the most isolated lights being 20 miles from the port at Mount Desert Island and is considered to be very exposed to the elements.
