This is said to be the origin of the Saraswati river coming out and going underground again. This river is not visible anywhere from its source up to Allahabad Sangam in UP, where it is said to merge into Ganga river along with Yamuna river. Very close to the visible part of the river Saraswati, there is very small water stream said to be water from Mansarover Lake in Tibet.
The first 3 km can be travelled by a car or a bus. This stop is called "Mana". First point after the village Mana, the last habitat in the Indian side, is Bhim Pool. This is said to have been built by Bhim (of the Pandavas from the Mahabharata epic) for his wife Draupadi who could not cross the ridge. From here, there is a 4 km trek to the falls. No special gear for the trek is needed apart from some sturdy shoes.
