Travel Tips

there are lots of place to see in salem
someof them are
Poiman Karadu
9 kms from Salem is this particular spot, the likeness of a deer with 2 horns, seen from the plains to the east. The mysterious vision disappears when you get nearer. Hence the name.
Tharamangalam
24kms from Salem, this town is famous for the Kailashnatha Temple. The rotating lotus flowers made of stone, statues of Rathi-Manmatha, Vali-Sugriva and the Yali with rotating stone ball in its mouth are some of the beautiful sculptures.
Mettur Dam
One of the largest of its kind in the world, it was completed in 1934. The total length of the dam is 1700 m. The quantity of water stored is 93,500 million cubic ft, and the height of the dam above the riverbed is 176 ft. The dam provides irrigation facilities to Salem, Trichy and Thanjavur districts for 2,71,000 acres. The Mettur Hydro Electrical project is also quite large. A thermal plant is also coming up. The dam, the park, the major hydroelectric stations and hills on all sides make Mettur a good tourist's attraction
enjoy ur trip :)
