Riyue Tan and the wide basin of Nantou

Riyue Tan in Nantou combines a highland basin, Lalu Island and forested hills in central Taiwan, with more layers to notice.

Riyue Tan in Nantou is a highland lake in central Taiwan, known internationally as Sun Moon Lake. The water sits in a broad basin ringed by hills, with Lalu Island dividing its outline into two distinct forms.

Riyue Tan and its mountain setting

The lake lies in Yuchi Township in Nantou County, inland from Taiwan’s western coastal plains. It is associated with Mount Shuishe and Mount Dajian, which frame the water on opposite sides.Riyue Tan

Its elevation is around 760 m (2,493 ft), so the setting has the character of an upland lake rather than a lowland reservoir. The shoreline is bordered by slopes, harbours and temple platforms above the water.760 m elevation

The name, Lalu Island and the lake’s outline

The name Riyue Tan means “sun-moon lake” in Chinese. Lalu Island sits in the middle of the water and divides the lake into a rounder side and a crescent-like side.Lalu Island

That central island gives the lake its most recognisable form when seen from the shore or from the water. The surrounding hills and the island together create a basin that feels enclosed by land and water at the same time.surrounding hills
