Syntheri Rock is monolithic granite structure having a height of 300 ft, which is located in the dense Dandeli Wildlife Sanctuary. The River Kaneri that flows at this place passes along the side of this rock. Owing to the flow of the river from the vicinity, erosion has resulted in the rocks getting hollowed. The corners of this rock cave are inhabited by numerous pigeons.
Hives of rock bees can be seen hanging from the camp of Kali wilderness, located nearby. The site can be reached either by jeep or by walking through the dense forest.
