Ooty or Udagamandalam rightly described as "Queen of Hill Stations" by Pandit Jawaharlal Nehru, now sprawls over an area of 36 sq km with a number of tall buildings cluttering its hill slopes. It is situated at an altitude of 2,240 meters above sea level. Though the march of brick and mortar has laid waste its thick sholas which one saw in a bygone era, it still woos people from all over India as well as foreign countries right through summer, and sometimes in the winter months too. An added attraction for the tourists to Udagamandalam is the mountain train journey on a ratchet and pinion track which commences from Kallar, near Mettupalayam and wends its way through many hair-raising curves and fearful tunnels and chugs along beside deep ravines full of verdant vegetation, gurgling streams and tea gardens. The scenery, as it unfolds during the trip, is breathtaking, awe-inspiring and fantastic. One can notice a marvelous change in vegetation, as one goes from Kallar to Coonoor. At Kallar it is tropical and at Burliar-the next bus-stop as one proceeds from Mettupalayam-it is sub-tropical. Near Coonoor, it is humid with pines, blue gum (Eucalyptus globulus) and cypress trees. As we go from Ooty to Gudalur, the change in vegetation is striking. What a splendid interaction between climate and vegetation. It is therefore very appropriate that Mount Stuart called the whole road leading to Ooty from Mettupalayam, "One long botanical debauch."
