devi’s or david’s fall: a famous waterfall of pokhara where water coming from phewa lake vanishes into the earth. it is locally known as patale chhango (hells fall). here visitors can see river flowing out of lake phewa getting sucked into deadly vortex of a dark cavern that plunges into the depths of the earth. although waterfall is open to visitors throughout year, best time to visit is during the monsoon season when the floodgate of the phewa lake barrage is opened to ease the water level. during winter there is a mass decrease in the water volume of the phewa lake hence the dam is closed to maintain the water volume within the phewa lake.
