Dhanushkodi is in the state of Tamilnadu, India. It is situated at the south-eastern tip of India, in the island of Rameswaram. On one side is the Bay of bengal, on the other the Indian ocean, the two converging here at Dhanushkodi. It is a remote & barren place, without any permanent human settlement. The only natural dwellers are a large number of sea birds. The place is sacred to Hindus, as they believe that Lord Rama had built a bridge to Sri Lanka over the sea from this point. In fact, there is the remnant of some submerged bridge like structure (Called Adam's Bridge) which is clearly visible in satellite photos.
To reach Dhanushkodi one has to travel to Rameswaram, a place about 175 km from the nearest airport at Madurai in the state of Tamilnadu, India. Rameswaram is a fairly large town with a famous temple of Lord Shiva, & a host of other temples. Rameswaram is actually an island, connected with the mainland India by a railway bridge & a road bridge (over 4 km in length) over the sea.
Dhanushkodi is about 20 km from Rameswaram & easily approachable by jeeps & similar vehicles (preferably four-wheel drive). The last 8 or 9 km portion has no roads till date, & one has to travel on sand. The journey itself is very thrilling.
