Daily dolphin cruises slip out of Port Adelaide into the Adelaide Dolphin Sanctuary, where wild dolphins share the water with mangrove-lined channels and the eerie Ships Graveyard. Commentary covers maritime history, a 10,000-year-old mangrove forest, and an international bird sanctuary along the Port River. Private charters run on 16-, 32- and 100-seat vessels for events and weddings, alongside regular public sailings from South Australia's historic port.
