A couple of miles south of Graham's Harbour stands Dixon Hill Lighthouse. Built around 1856, it's the last hand operated lighthouse in The Bahamas. The lighthouse keeper must wind the apparatus that projects the light, which beams out to sea every 15 seconds to a maximum distance of 19 mi, depending on visibility. A climb to the top of the 160-foot landmark provides a fabulous view of the island, which includes a series of inland lakes. The keeper is present 24 hours a day. Knock on his door, and he'll take you up to the top and explain the machinery. Drop $1 in the box when you sign the guest book on the way out.
