Hello Travelers,
Avani is located near Koti Lingeshwara Temple. It is approx 16 Kms from Bangaru Tirupati and 25 Kms from Koti Lingeshwara Temple.
One hour should be fine to see the temple and another hour or so to spend trekking the small hill.
It is a historical place dating back to Ramayana times as per the Priest of Avani Temple. There is also a small hill which people climb. Valmiki Ashram is on top of the hill. It is said that Luv and Kush had fought with their father Lord Rama here.

Here are some pics.
See you all in my next post. Bye :)
