The Khandagiri and Udayagiri Caves are twin hills of rock-cut caves on the edge of Bhubaneswar, carved around the 2nd century BCE as dwellings for Jain monks — among the oldest surviving monuments in the region. Udayagiri’s Rani Gumpha and the Hathigumpha inscription of King Kharavela are the highlights.
They sit minutes from Lingaraj Temple and Dhauli, so they slot neatly into a half-day Bhubaneswar heritage loop.
