For dramatic vistas of sand and sea, head to the lighthouse viewing area on Shore Rd. The landmark lighthouse dates to 1878; its light is visible 15 miles out to sea. No reservations are taken for the tours, so just show up. Note that in May, June, September and October, the tours take place on the first and third Wednesdays of the month, while in July and August they happen every Wednesday.
