Chandra Taal, Glacial lake in Lahaul and Spiti district, India.

Chandra Taal is a glacial lake situated in the Lahaul and Spiti district at an elevation of around 4,300 meters in the eastern Himalayas. The water body stretches roughly 1.7 kilometers in length with a width of about 400 meters and lies in a high-altitude cold desert region.

In 1871 Harcourt, Assistant Commissioner of Kullu, reported a plain of good grass north of Chandra Taal where shepherds from Kullu and Kangra brought large herds to graze. Overgrazing has since degraded these grasslands. The lake lies on the Samudra Tapu plateau and is one of two high-altitude wetlands in India designated as Ramsar sites.

The name Chandra Taal means "moon lake", taken from the lake's crescent shape. In summer, shepherds still bring herds to the surrounding meadows, as they did when Harcourt, Assistant Commissioner of Kullu, reported a plain of good grass north of the lake in 1871. The lake is one of two high-altitude wetlands in India designated as Ramsar sites.

The lake is best visited between June and September when trails are accessible and weather is most favorable for travel. A short walk of roughly one kilometer from the parking area reaches the shoreline, and preparation for high-altitude conditions is important.

The Hindi Wikipedia article notes that no water source is visible feeding the lake, while an outlet is clear, suggesting the water rises from underground. The lake also holds an island in its middle, called Samudra Tapu, and lies about 30 km from Suraj Tal.
