Surajkund Hot Spring

Surajkund, also known as Surya Kund, is a hot spring in Belkapi gram panchayat, Barkatha block, Hazaribagh district, Jharkhand, 5 km from Barkatha on NH 19, the old Grand Trunk Road, and 72 km from Hazaribagh. Its water contains sulphur and is said to have healing properties. It is claimed to be India's hottest spring, with a surface temperature of 87 °C and an average of 165 °C below ground, and it ranks among the most promising geothermal sites in the state.

There are five kunds in one place, the Surya, Lakshman, Brahm, Ram and Sita kunds, with water that ranges from cool to very hot. In recent years a Durga temple has been built at the site, and the state tourism department has plans for spas and other facilities.
