Devi's Falls (Nepali: पाताले छाँगो) is a waterfall located at Pokhara in Kaski District, Nepal. The water forms a tunnel after reaching the bottom. This tunnel is approximately 500 feet (150 m) long and runs 100 feet (30 m) below ground level. On 31 July 1961, a Swiss couple went swimming but the woman drowned in a pit because of the overflow. Her body was recovered three days later in river Phusre with great effort. Her father wished to name it "David's falls" after her daughter's name but changed to Devi's Fall. Its Nepali name is Patale Chango, which literal meaning is Paatal Ko Chango means "Underworld's Waterfall". This is one of the most visited places in Nepal. After exiting the tunnel, the water passes through a cave called Gupteshwor Mahadev Cave or "cave beneath the ground". The Phewa Lake dam is the water source of this falls. The cave also acts as a tourism site because it has complex designs and people even forget the way inside the cave.
