Semau Island

Semau is a small island off the southwest coast of Timor in East Nusa Tenggara, Indonesia, administratively part of the Kupang area. It lies roughly 25 km west-southwest of the city of Kupang and is one of the nearer offshore islands to the provincial capital.

The island is visited for its beaches, nearshore coral reefs and quiet coastal villages rather than for large tourist infrastructure. Shallow bays and reefs support snorkeling and small-scale fishing, and visitors usually travel there by boat from Kupang.

Semau is occupied by local communities who rely primarily on fishing and small-scale agriculture; settlements are concentrated on the coasts. The island has long been part of local maritime routes between West Timor and nearby islands.

Geographically it sits in the Flores Sea, with low coastal plains rising to modest interior hills and rocky shoreline. The closest major urban center is Kupang on West Timor, which serves as the transport and supply hub for trips to the island.

• Access: Regular boat connections and informal charter boats link the island with the port city of Kupang on Timor, making Kupang the usual access point.
• Activities: Coral reefs and shallow bays offer snorkeling close to shore, and small coastal villages provide simple local accommodation and supplies.

Semau is reached by boat from Kupang or nearby islands in the Timor Sea. The closest major air hub is Kupang on West Timor; from there travelers arrange local ferry or charter boat transfers. Expect irregular schedules and plan transport in advance.

• Boat charters from the nearby larger islands (e.g., Rote Island) are typically how visitors arrive - plan and confirm transport in advance.
• Bring reef-safe sunscreen and a snorkel; the surrounding waters are clear enough for basic snorkeling near rocky points.
• Respect local communities and any protected areas; Semau's beaches and reefs are fragile and less serviced than tourist islands.
