Named after the nearest village, Jonha is also known as Gautam Dhara as Lord Buddha is believed to have bathed here. A temple and ashram dedicated to Buddha was built atop Gautam Pahar by the sons of Raja Baldevdas Birla. A fair held in the place every Tuesday and Thursday is also quite renowned amongst the tourists.
A sign clearly proclaims that the ashram was originally meant for people of the Hindu faith as well as all branches of arya dharm (Buddhists, Jains, Sikhs, Sanatani and Aryasamajis). Locals also call Jonha the Gunga Nala because the stream apparently comes from Ganga ghat. 453 steps take you down to the waterfall and to the farflung villages of Konardih and Duarsini on the other side of the stream.
This waterfall lies at the edge of Ranchi Plateau and is counted as one amongst the hanging valley falls. It gathers water supply from rivers Ganga and Raru to form the fall. It drops water from a height of 43 m. To see the surrounding areas of this fall, a descent of 500 stairs is required.
