As distances to sites of interest are short, cycling is the main means of transport on the island. Tourist activities include golf (9-hole), lawn bowls, tennis, fishing (including deep-sea game fishing), yachting, windsurfing, kitesurfing, kayaking, and boat trips (including glass-bottom tours of the lagoon). Swimming, snorkelling, and scuba diving are also popular in the lagoon, as well as off Tenth of June Island, a small rocky outcrop in the Admiralty group where an underwater plateau drops to reveal extensive gorgonia and black corals growing on the vertical walls. Other diving sites are found off Ball's Pyramid, away, where trenches, caves, and volcanic drop-offs occur.
