Jaco IslandAbout Jaco Island
Jaco Island is a small, largely uninhabited island off the eastern tip of Timor-Leste in Lautém Municipality. It is noted for white coral sand beaches, clear coastal waters and reef snorkeling.
The island’s beaches and fringing coral reefs make it a destination for day trips, swimming and snorkeling in relatively clear water. There are no permanent settlements and the shoreline is prized for its natural, undeveloped character.

The island sits off the easternmost tip of Timor-Leste, close to the mainland villages of Tutuala and Lospalos in Lautém Municipality, and is part of the coastal island groups at the country’s far east.
