Kosrae (pronunciation: koh-), formerly known as Kusaie or Strong's Island, is an island in Federated States of Micronesia. The State of Kosrae is one of the four states of the Federated States of Micronesia, and includes the main island of Kosrae and a few nearby islands and islets, the most significant of which is inhabited (1,500 people) Lelu Island.
Kosrae's land area is 110 km2, sustaining 6,600 people. Tofol is the state capital. Mt. Finkol is the highest point at 634 m.
Kosrae, the easternmost of the Caroline Islands, has a population of 6,616 (2010 census). It is located approximately 600 km north of the equator, between Guam and the Hawaiian Islands. It has a land area of approximately 110 km2. Some parts of the island are experiencing coastal erosion.
Kosrae is a high island that is largely unspoiled. It is becoming a destination for scuba divers and hikers. The coral reefs that surround the island are kept in pristine condition through an extensive mooring buoy system, installed and maintained by concerned expat dive operators with the help of the government's Marine Resources office. The reefs are largely untouched, and contain miles of hard corals, some said to be thousands of years old.
Dense vegetation and steep mountains keep the island largely undeveloped. Viewed from the ocean, the island's distinct shape resembles a female body. This has led to the island being called "the island of the sleeping lady."
Kosrae International Airport (IATA code KSA) is located on an artificial island within the fringing reef about 150 m from the coast and is connected to the main island by a new bridge that opened to the public in January 2016. It is served by United Airlines (formerly Continental Micronesia) Island Hopper 737–800 flights (thrice a week in each direction) between Hawaii and Guam, stopping at other FSM (Pohnpei and Chuuk) and Marshallese destinations on the way. Nauru Airlines also connect weekly with their fleet of 737–300 jets to Brisbane in Australia and Nadi in Fiji.
There is one significant nearshore island within the fringing reef around Kosrae, which is Lelu Island, and it is only 2 km2 in area, but with a population of around 1,500. It belongs to Lelu municipality, which includes the area around Tofol, the state capital. Other very small, uninhabited islands within the fringing reef are, Yen Yen and Yenasr (also in Lelu municipality), the airport island, Kiul, Mutunyal, Sroansak (Tafunsak municipality), and Srukames (also Tafunsak municipality, Walung part).
