Jaco Island is a deserted island at the easternmost point of Timor-Leste, covered in diverse forest and ringed by flawless white sand beaches lapped by azure waters that shift from light blue to a deeper shade, creating a breathtaking gradient of blues.
Politically it is part of Tutuala subdistrict in the district of Lautém. Spanning approximately 8 km², the island is separated from the Timorese mainland by a narrow channel crossable only by small boat.
Uninhabited and considered sacred by the indigenous peoples, it is illegal to spend the night on the island. Day visits, however, are fully permitted — Tutuala Beach on the mainland sits just across the shallow channel.
Getting to Jaco Island
The only way to reach Jaco is by boat from Tutuala Beach. Speak with the local fishermen there who offer return crossings for a standard fee:

Important: Do not attempt to swim across. The currents through the narrow passage are swift and dangerous.

Biodiversity and Conservation
Jaco Island is home to endemic bird species, including:

Geographic Context: The Lesser Sunda Islands
Jaco Island is part of the Lesser Sunda Islands, an archipelago south of the Malay Archipelago that together with the Greater Sunda Islands forms the broader Sunda Islands group.
The Lesser Sundas form a volcanic arc — the Sunda Arc — shaped by subduction along the Java Trench. Politically, the island group is divided between:
- Timor-Leste (independent state)
- Indonesia — provinces of Bali, West Nusa Tenggara, and East Nusa Tenggara
