This place is highly picturesque, visit caves, double-decker root bridge which is a marvel in modern civilization. The whole place is surprisingly quite and pleasant most of the time. There is a place called Dawki with a river Umngot river. The water of this river is extremely clear, clearest I have seen in India, being at the border of India and Bangladesh, makes it a popular tourist spot. Visit Mawlynnong, cleanest village in India. It is an hour away from Dawki and the route to this place is through quite forest of areca nut, you can smell it all along the way. The villagers have done an amazing job of keeping it green and clean. You will not feel they have deliberately done to attract tourists, however, they have made it a habit to have everything in place.
