About this site
Hong Kong is a reef site near Una-una island in the Tojo Una-una area of the Gulf of Tomini, off the Sulawesi coast of Indonesia, in waters shaped by the steep volcanic topography left by the island's Colo volcano. It reaches a maximum depth of around 24 metres, is rated an intermediate dive, and typically sees light current, making it manageable for divers with some experience. Divers have reported Napoleon wrasse, nudibranchs, octopus, and pipefish here, and dive operators typically run trips out from small coastal settlements in the area.
