Sigura-gura Waterfall

Sigura-gura Waterfall is a tall waterfall on the Asahan River in Pintu Pohan Meranti, Toba Regency, North Sumatra, near the outflow of Lake Toba. Standing approximately 250 meters high, it is considered one of Indonesia's tallest waterfalls. The falls are closely linked to the Sigura-gura Dam and hydroelectric power station. Surrounded by forested hills and a steep river valley, it is notable for its powerful cascade and scenic natural setting.

Visitors can expect a tall, powerful cascade on the Asahan River set in a steep, forested river valley downstream from Lake Toba. The waterfall is viewed from designated viewpoints and roadside areas near the Sigura-gura Dam. The surroundings include dense vegetation, rocky riverbanks, and hydroelectric infrastructure. Visitors can observe the main drop, hear the strong water flow, take photographs, and explore the valley viewpoints. Access involves walking on uneven ground and steps.

The waterfall is formed by the Asahan River which drains Lake Toba. The site gained prominence with the development of the Asahan River hydroelectric project and the construction of the Sigura-gura Dam in the 1980s, one of Indonesia's major hydropower developments, which utilizes the river's steep drop including the waterfall section.
