Follow the light of the full moon on these rare nighttime climbs up the 199 cast-iron spiral staircase steps to the top of the Cape May Lighthouse. Enjoy a nighttime view nearly 156 feet above the Delaware Bay and Atlantic Ocean. The 1859 Cape May Lighthouse is a state historic site and the third beacon on this site. Since it opened to the public in 1988, more than 2.5 million visitors have climbed to the top, but far fewer have climbed at nighttime.
