Heidi's Honeymoon Grill (also listed locally as Heidi's Hilltop Grill after a move up Providence Hill) is a casual Water Island bar and grill with shaded hilltop seating overlooking Elephant Bay. Tourism materials highlight fish tacos, burgers, and drinks; Facebook operator updates note seasonal schedules, so confirm open days and cash-or-card policy before you take the ferry from Crown Bay.
A Second World War defensive outpost on Water Island that was never finished, construction stopping when the war ended in 1945. An underground bunker, tunnels, gun turrets and an observation deck remain, and visitors walk the underground site and climb to the deck.
Dinghy's sits on Honeymoon Beach on Water Island, reached by the Water Island ferry. The bar and grill rents beach chairs and umbrellas, and there is paddleboarding, snorkeling, beach volleyball and tennis on site.
