Avalanche Lake, Ooty, Lake in Nilgiris district, Tamil Nadu, India

Avalanche Lake is a body of water in the Nilgiris district of Tamil Nadu, India, set among rolling hills and flowered slopes. The lake is surrounded by winding paths that follow its edge, and a small fish farm operates near the shore.

The lake formed after a large landslide in the early 1800s, which dammed the valley and created the basin. Over time, the area became a stop for travelers exploring the Nilgiris, and a fish farm was later set up to support trout fishing.

Local families often come here for a day out, spreading mats near the water and sharing food while children play along the bank. The name comes from a landslide, and residents still point to the slopes where it happened when they tell the story to visitors.

The paths around the lake are uneven in places, so wear shoes with good grip and allow extra time if you walk the full loop. Early mornings tend to be clearer, and the area is best explored on foot, as some tracks become muddy after rain.

The lake is fed by streams from the surrounding hills, and the water stays cool even in summer, which surprises visitors who expect warmer temperatures. Trout raised at the nearby farm are released into the lake, so anglers often catch fish that were bred just a few steps away.
