Jog falls is the 2nd largest in terms of volume of water. The valley is huge. The water falls from Sharavati River. There is a dam. So if the rains are heavy then the dam water is released due to which volume of jog falls increases. But, this is unpredictable. August is the best season to go.
The Sharavati, flowing over a very rocky bed about 250 yards (230 m) wide, here reaches a tremendous chasm, 290 m (960 ft.) deep, and the water comes down in four distinct falls. The Raja Fall pours in one unbroken column sheer to the depth of 830 ft. (250 m). Halfway down it is encountered by the Roarer, another fall, which precipitates itself into a vast cup and then rushes violently downwards at an angle of forty-five degrees to meet the Raja. A third fall, the Rocket, shoots downwards in a series of jets; while the fourth, the Rani, moves quietly over the mountain side in a sheet of foam. The Tourism Department has built steps from the viewpoint to the bottom of the hill where the waterfall can be seen at the opposite side. There are approximately 1400 steps built to reach the bottom of the hill. Due to security reasons, visitors are not allowed to go near the water.
