Taiwan is an island state surrounded by ocean, with a 1,600 km long coastline. Eastern Taiwan faces the large and deep Pacific Ocean where the 'Black Tide' not only brings in warm waters, but also the Migratory fish along. The western Taiwan on the other hand is rich in nutrients, creating an amazing marine ecosystem. There are six major diving regions with brilliant visibility and varied marine life year-round: Kenting, Green Island, Xiao LiuQiu, Orchid Island, Northeast Coast and PengHu. Divers can enjoy both shore and boat diving.
