Patalpani waterfalls are located near Mhow, very close to Indore. The falls are huge and the view is beautiful. Ideal time to visit would be soon after monsoon when the water level is high. However, you have to be very careful as the river here is notorious for flash flooding and the terrain is quite dangerous. Avoid going too close to the falls and exercise caution. It is a good place for one-day picnic from Indore, but remember to carry your own food and water.
