It was a very comfortable bus journey operated by Kallada Travels. The bus was AC sleeper Mercedes Benz which made the travel very good. As it was an overnight bus journey, I could made the best use of my time. I started at night and was there by morning. Travel by bus was a very good option form Bangalore if you don't want to fly and the bus tickets are not available even couple days before the actual journey, then you can always travel by bus.
