I am planning to visit Mahanandi, Yaganti , Ahobilam and belum caves in the month of august. I am planning to board 56504 from Vijayawada to nandyal. As per my knowledge nandyal is closer to above specified places. In order to cover the first three places one day is sufficient or it is better to spend two days and cover all the places. Some senior members of rayalaseema please guide me accordingly. Return from Nandyal to Vijayawada I will take amaravathi.
