"Dating back to 1791, this is the oldest lighthouse in Maine and arguably the most beautiful in New England. It contains an excellent museum (in the former Keepers' Quarters) delving into its history, as well as a gift shop. Just outside is Fort Williams Park, made up of 90 acres filled with coastal hiking paths and picnic tables, gardens, and a beach. Note that the park is open year round from sunrise to sunset, but the museum and shop are open daily in the summer, and weekends only during the off-season." - Alexandra Hall
