There is an AP tourism sponsored resort "Haritha resort", you can do online bookings. Unfortunately, there are no other modes of accommodation available. However, you are free to lodge your own tent.If you or someone in your group understands Telugu, this may help you a lot. Since, this place is still trying to find it's mark on tourism circle, English or Hindi language is not common here . You can essentially arrange things like food or accommodation easily, if you understand the native language.Bellum CavesThe Belum Caves is the largest and longest cave system open to the public on the Indian subcontinent, known for its speleothems, such as stalactite and stalagmite formations. I just loved it. AP government is trying to put these places in a better shape and make it tourism friendly. This is almost 60 KM away from Gandikota and it's a must visit if you are in that region.
