Hirni Falls, Waterfall in West Singhbhum district, Jharkhand, India

Hirni Falls is a waterfall on the Ramgarha River in West Singhbhum district, Jharkhand, where the river drops 37 metres at the edge of the Ranchi plateau near Bandgaon. The fall runs over dark, stepped rock as a narrow white column that widens toward its base, with green vegetation clinging to the wet rock face and dense foliage arching over the top.

The waterfall site formed over millions of years through geological processes when tectonic movements shaped and lifted the Ranchi plateau. This uplift caused rivers to cut deeper into the rocky surface, gradually carving out the cascades that exist today.

The waterfall's name comes from the Hindi word 'hirni', meaning female deer, reflecting the animals that roamed the surrounding forests. Today, visitors may still spot these creatures in the woodland, especially during early morning or late afternoon hours.

The best time to visit is during the monsoon season from June to October when water flow is strongest and pools are full. Reaching the site involves some walking through forest terrain, so sturdy footwear and drinking water are recommended.

Hirni Falls lies about 20 km from Khunti and 62 km from Ranchi, off the Ranchi–Chaibasa road; the Hindi Wikipedia places it on National Highway 20, 62 km south of Ranchi and 68 km north of Chaibasa. The Ramgarha River drops 37 metres at the edge of the Ranchi plateau near Bandgaon.
