Beavertail State Park
Water conditions range from tranquil to harrowing at this park straddling the southern tip of Conanicut Island. In rough weather, waves crash dramatically (and dangerously) on the rocky point. On a clear, calm day, however, the park's craggy shoreline invites sunning, hiking, and climbing. There are portable restrooms open daily, year-round. On about a dozen dates (July–October), the Beavertail Lighthouse Museum Association (beavertaillight.org) opens the Beavertail Lighthouse, the nation's third-oldest lighthouse (established 1749), letting you climb the 1856 tower's 49 steps (and then a 7-foot ladder) to enjoy the magnificent panorama from the observation catwalk. A museum occupies the lighthouse keeper's former quarters; the lighthouse's last "beehive" Fresnel lens is on display. The old fog signal building has a saltwater aquarium with local species of fish. Both are open seasonally.
