Jonha Falls, Natural waterfall in Ranchi district, India.

Jonha Falls is a waterfall in Ranchi district, India, where the Gunga River joins the Radu River. The water drops roughly 140 feet (43 meters) straight down from the plateau edge, throwing up constant spray and mist at the base pool below.

A Buddhist temple sits atop Gautam Pahar near the falls, standing there for several centuries. Raja Baldev Das Birla built the structure, connecting it to older religious traditions of the region.

The falls are also called Gautamdhara, after Gautam Pahar, the hill where they sit. A tourist rest house here holds a Buddhist shrine with a statue of Gautama Buddha, and a temple and ashram dedicated to Buddha were built on the hilltop by the sons of Baldeo Das Birla. A fair is held at Jonha every Tuesday and Saturday.

Two paths lead down to the falls: a road through Jonha Fall Resort or 722 steps from the upper viewing area. The stairway route is steep and slippery when wet, so sturdy footwear helps for the entire descent.

The drop formed at a point where the riverbed suddenly changes slope and the plateau breaks off. This geological threshold means the water does not flow over gentle steps but falls freely into space below.
