Less than 7,000 miles of land lost in 70 million square miles of ocean, the remote Hawaiian chain of islands has always been a challenge for navigators. This episode highlights Kilauea Point Lighthouse, located on the Kilauea Point Wildlife Refuge on Kauai Island; Makapuu Point Lighthouse (above), the biggest and most powerful of the lighthouses in Hawaii, located on the eastern end of Oahu, Hawaii’s most populous island; and the Diamond Head Lighthouse, located near the foot of the extinct Diamond Head volcano. The beautiful and historic keeper's dwelling is now the official residence of the Coast Guard's 14th District Commander, Admiral Joseph McClelland.
