Terengganu formerly spelled Trengganu or Tringganu, is a sultanate and constitutive state of federal Malaysia. The state is also known by its Arabic honorific, Dāru l-Īmān ("Abode of Faith"). The coastal city of Kuala Terengganu which stands at the mouth of the broad Terengganu River is both the state and royal capital as well as the largest city in Terengganu. There are many islands located close to the coast of Terengganu state, such as Redang Island.
Terengganu is situated in eastern Peninsular Malaysia, and is bordered in the northwest by Kelantan, the southwest by Pahang, and the east by the South China Sea. Several outlying islands, including Pulau Perhentian, Pulau Kapas and Pulau Redang, are also a part of the state.
There are three airports located in Terengganu, of which two of them are open to the public. Sultan Mahmud Airport located in Gong Badak, Kuala Nerus is the state's main airport and serves as a main gateway by air to and from Terengganu. Other public airport is the Redang Airport, located in Redang Island off the coast of Terengganu.
Kerteh Airport, located in the town of Kerteh, Kemaman is the state's second largest airport but is not open to public because the airport is owned and operated by Petroliam Nasional Berhad or Petronas via its East Coast Regional Office (ECRO), and was built to serve the purpose of airlifting its employees and ExxonMobil employees to their various oil platforms located 100–200 km offshore South China Sea. The airport although small, has a single 1,362 m (4,469 ft) long runway which can accommodate a Boeing 737-400 aircraft.
A military air force base, RMAF Gong Kedak is located between the borders of Kelantan (Pasir Puteh) and Terengganu (Besut) and has an airstrip which crosses the two state borders.
