Mount Thullier

Mount Thullier is the highest peak of the Nicobar Islands, rising 642 meters (2,106 feet) above sea level in the Indian Ocean. Several major rivers flow outward from this summit, including the Galathea River.

The mountain was formed through tectonic movements over millions of years, creating its ridged structure of compressed rock. These geological processes shaped the Nicobar Islands' highest elevation into its current form.

The mountain holds meaning for the Nikobarese and Shompen communities who have inhabited these islands for generations and continue their traditional ways of life in the surrounding forests. Local presence shapes how the landscape is used and valued today.

The summit lies within protected nature reserves that restrict general access and require special permissions to visit. The tropical environment means visitors should prepare for humid conditions and dense vegetation throughout the surrounding terrain.

The summit sits within a biosphere reserve that protects species found nowhere else in the world, making it a remarkable ecological hotspot. This isolation has created an unusual concentration of rare wildlife and plants that evolved separately from mainland populations.
