Thanks for your feedback appus.
The reason why I kept replying to my own post is because, I wanted to relate the photos to the description I have made. More over, I am new to this website, I was wondering if I can describe each picture I upload. I could not find this option anywhere.
There is a Panchamukhi Hanuman temple within 20 Kms from Mantralaya. The roads are not all that good as of what I have heard. If you have big vehicle, you can mange to visit these places. You can also rely on private vehicles. This place is full of rickshaw's. You can hire one and visit these places. My suggestion is to hire a local Auto rickshaw, if you have a vehicle with less ground clearance. Also, there is a place called Bichale. As of what I have heard, Guru Raghavendra has spent lot of time even in Bichale. Since we decided to leave the place very next day, we missed out on visiting these places. The plan was to visit Panchamukhi as well as Bichaale on 26th and leave Mantralaya on 27th. Its a last minute decision to leave Mantralaya one day before so we failed to visit these places. 90% of the people don't miss visiting Panchamukhi and Bichale.
There is Manchalamma temple attached to mutt premises. People say that, we must take darshan of Manchalamma before taking the darshan of Brindavana.
Also, if you can inquire with local people, you can get the good view of river Thunga-badra. We observed people walking on rocks and moving further towards the river. I could not manage to move further with the aged people around.
