Gupteswar is a cave temple located on the banks of Kolab River, about 80 km from Koraput. Situated on a lime stone hill amidst scenic bliss, the cave shrine is dedicated to Lord Shiva. The temple houses a sacred swayambhu Shivling called Gupteswar, which literally means the ‘Hidden God’. Shivratri is the major festival celebrated here amidst much pomp and splendor. The fame of the temple is not restricted to Orissa but it is also well known in other parts of the country. The people of Chhattisgarh refer to the shrine by the name ‘Gupta Kedar’. Gupteswar can be reached through a forest tract which starts from the east of the Ramagiri Hill up to a distance of 19 km.
