Unchalli Falls, otherwise known as Lushington Falls, is located at a distance of 30 km from Sirsi, in Siddapur Taluk. In 1845, J.D. Lushington (The District Collector for the British Government) discovered this fall, thus giving this waterfall his name.
Unchalli Falls is renowned among the natives as Keppa Jog, which literally means 'deafening'. Originating from the Aghanashini River, this waterfall is at a height of 381 feet (116 meters). The stream originating from Shankarathirtha in Sirsi joins Manjaguni stream to form the Aghanashini River. It can be visited at any time of the year and offers an excellent view of the surrounding vegetation and water falling down rocky slopes.
