The scenic Shilloi Lake is located at the base of the mountain ranges, the Patakai Range, that run along the Myanmar Border. When tourists visit this attraction, they also get to see the magnificent hills bordering the foot-shaped pristine natural water body and also explore them through trekking, hiking, nature walks etc. Many student excursions are arranged to the lake for studying the flora and fauna of the region. The natural environment is also deemed perfect for birdwatching, especially to observe the Siberian Cranes.
The lake is spread over an area of 0.5 to 0.30 sq. km. and is 4 metres deep. According to legend, a couple once lost their daughter in the middle of this lake. Even after searching endlessly, they were unable to find her. The only thing that is not allowed at Shilloi Lake is disturbing the water table while entering the waters. There is a prophecy that the waters of the lake should never be dried. So, any activities that affect the water are strictly prohibited.
