Your troubles don't end once you get the entrance tickets. Because the tickets to the actual boat ride will be issued only at the counters near the lake boating area which is another 2 kms away. From the gates of the sanctuary we left our car and took an auto to reach the boat house(auto drivers queue up at 3 am to book their place at the head of the queue). For the 2 kms, autos charge(robbed would be the right term)200 bucks to the inner gate of the sanctuary. From there, it is a sprint for another 500 metres to the ticket counter. After all these troubles, I just about managed to get the tickets just in the nick of time. I heard from the authorities that to avoid these troubles one can stay at the KTDC Aranya Nivas, inside the sanctuary which provides access to the boat rides.
