Dvaitavana is a sacred forest named for the lake Dvaita that lies within it. It was one of the forests where the Pāṇḍavas lived during their twelve-year exile, as the Vana Parva of the Mahābhārata tells.

The forest and its lake

Dvaitavana takes its name from the Dvaita lake in its midst. The Dvaita lake is a lovely body of water within the forest.

The Pāṇḍavas at Dvaitavana

Bhīma killed the rākshasa Kirmīra on the midnight path leading to Kāmyakavana. After this the Pāṇḍavas went on to the Dvaitavana region and stayed there. (Mahābhārata, Vana Parva, Chapter 11)

Their exile was a time of moving between holy forests: Kāmyakavana, Dvaitavana, and later the forests of the Himālaya, during Arjuna’s tapas (austerity) and during the tīrtha-yātrā (pilgrimage) under the guidance of Lomaśa.
