Siri Waterfall

Siri Waterfall is a natural waterfall on Gaua Island in Vanuatu, fed by a crater lake perched at high elevation and cascading down through dense forest. The water plunges over steep rock faces and flows into a river system below, surrounded by lush vegetation and steep terrain.

The name comes from the Nume language and shares linguistic roots with other regional languages, all deriving from an ancient Proto-Torres-Banks word. This linguistic connection reflects the long history of settlement and exchange among the islands in this region.

The waterfall path passes through former settlements where you can observe how island communities organized their spaces and used the surrounding forest. These areas show traditional patterns of daily life that remain visible in the landscape.

Visiting requires a multi-hour forest trek guided by experienced locals, so start early and be prepared for a demanding walk through challenging terrain. Wear appropriate footwear and clothing for wet, muddy conditions, as the route passes through dense rainforest and along river courses.

The water source is a freshwater crater lake sitting about 600 meters above sea level on one of the Pacific's most active volcanic islands. This hidden highland reservoir feeds the waterfall far below, creating a remarkable connection between the volcanic geology and the flowing water.
