The only direction that we had got was that the lake was close to the Art Of Living Campus. Since it was Ganesh Weekend we decided this was an ideal short trip and we could be back before 10:00 am.
After being misguided once we finally managed to take the right road. One had to go past the Art of Living campus and take a left at the main junction of the next village, after that take the left at Gulakamane village. One can even ask for TK falls and will be guided to this place. (TK Falls is 2 Kms from the Lake)

The whole intention of this trip was to bird watch. When we got there initially except for the beautiful lake, we didn’t see any birds and we were disappointed. But as we walked around the lake we observed folks of muniya, ducks, kites, weaver bird building its nest, white browed bulbul, parakeets, cuckoo, myna, laughing dove, ashley premia, kingfisher, coucal to name a few.

We spent about 2 hours here and then it was time to leave. Though this heaven for bird watchers is close to Bangalore it still remains known to a selected few.

So when the train stopped at a signal we hopped off it and started walking. We walked through 6 tunnels both long and short and we managed to do this without a single torch.
We were later told that it could have been dangerous to walk without torch as the tunnels were sometimes home for snakes. The sights during the walk were beautiful and worth every minute we spent.
Since we were told the train back to Castle Rock was only at 5 pm we decided to walk a little further, here laid the most beautiful tunnel passage. 2 tunnels separated by a small waterfall. The water fell from the openings of the tunnels and the bright sunlight made the water drops sparkle.
Since there was no one there we had a chance to experiment with our camera. Another 10 mins of walking we were opposite Dudhsagar waterfalls and it looked lot more majestic from here. 
Though the view took our breath away the place was so crowded and dirty that we didn’t feel like spending more than 5 minutes here.
Having seen pictures of the falls before we had high expectation but when we got here, there were more people than water. Just as we were giving up hope we spotted nature at work; a rainbow started to form around the falls and stayed for about 5 minutes. It was truly an amazing sight.
We spent some time admiring this and as it disappeared we decided to head back. The rainbow remained the topic of discussion all the way back.
