Whitewashed Swallowtail Lighthouse (1860) is the island's signature vista, cleaving to a rocky promontory about 1km north of the ferry wharf. Access is via steep stairs and a wooden footbridge. Since the light was automated in 1986, the site has been left to the elements. Nevertheless, the grassy bluff is a stupendous setting for a picnic. You can explore the lighthouse on your own (for a fee); even when it's closed it's illuminating, set where it is and all.
