For many who visit Hilton Head year after year, the Harbour Town Lighthouse is a symbol that vacation has started. With 114 steps to the top, it's tall enough to offer great views of Hilton Head but still climbable for families with young kids. The lighthouse also features a museum that highlights fun facts (did you know it's looked after by one of the few female lighthouse keepers in the country?) as you ascend. A gift shop at the top sells an extensive collection of models and books. Try to visit on a cool day with few crowds as the interior isn't air-conditioned (though there are fans). The lighthouse is located within the Sea Pines Plantation Resort, which charges a $6 gate fee for non-guests. Make a day of it and visit the town shops, restaurants, and beach while you're there.
