Emerald Lake is located in the Nilgiris district of Tamil Nadu, situated within the Silent Valley region of the Nilgiri Hills. The lake is fed by the Avalanche and Parsons Valley streams, creating a high-altitude reservoir environment. It is surrounded by tea plantations and dense shola forest, which is native to the higher altitudes of the Western Ghats. The site functions primarily as a water catchment area and is noted for its high biodiversity of bird species. The shoreline features gently sloping banks that contrast with the steep, forested hillsides characterizing the Nilgiri landscape. It is situated approximately 20 kilometers from the central hub of Ooty. The area is part of a protected ecosystem, necessitating careful visitor behavior to maintain water quality.
