- Khandagiri and Udayagiri Caves have derived their names, owing to their location on two hills, Udayagiri and Khandagiri. There are Kumari & Kumara Parvatas(hills) in the Hathi Gumpha inscription. These caves are located in such a way that they face each other across the road. These two hills represent one of the earliest groups of Jaina rock-cut architecture in Odisha in the field of architecture, art, and religion. These caves are also called Lena in the inscriptions they were dug mostly during the reign of Kharavela for the abode of Jaina monks during 1st century BC. These caves were first noticed by A. Stirling in 1825 AD.
- There is a total of eighteen caves in Udayagiri and fifteen caves in Khandagiri. These caves have rows of cells that open towards the common open space. The doorways are designed with unique carvings of animals, creepers, and flowers. Few caves are double storeyed. Ranigumpha, Swaragpuri-Manchapuri are double storied. Ganesh gumpha cave is a must to visit.
- Most of the caves have rock cuts which are believed to have been dwelling cells and meditation quarters for many Jain monks in those times. It is said that many monks used to live there under harsh conditions. They have also been able to produce stunning and intricate sculptures depicting the royalty, courts, religious symbols, and ordinary life of the society. It is one of the most visited tourist attractions in eastern India.
- These caves are open from sunrise to sunset throughout the year. The peak tourist season, though, is during the months from October to March. Across the road, the Khandagiri cave offers the best views over Bhubaneswar from its summit. Many tourists enjoy the impressive experience that enhances the journey.
