The Tenggol group of islands is the most southerly of Terengganu's Marine Parks. It consists of Pulau Tenggol, Pulau Nyireh (Nyireh Island), Tokong Timur, Tokong Talang, Tokong Burung and Tokong Kemudi.
The main island, Pulau Tenggol, is about 50 hectares in size and is one of the most beautiful and serene islands off Peninsular Malaysia's east coast. It is also famous for its spectacular rocky cliffs that offer many excellent dive sites. Here, one can find pristine coral formations and a number of submerged rocks with excellent coral growths. The deep waters surrounding the island offer good visibility especially during the months of April until June.
Marine life that can be seen here includes sharks, rays, nudibranch and a wide variety of hard and soft coral. Before being declared a marine park, Pulau Tenggol was a favourite hunting ground for spear-fishermen, particularly for snappers and groupers.
