The city is a base for visit to Horton Plains National Park .Horton Plains is a National Park and the highest plateau in the island at an altitude of 2,100 to 2,300 meters (6,900 – 7,500 ft) consisting of grassland interspersed with patches of forest, with some unusual high altitude vegetation. The Plains are a beautiful, silent, strange world with some excellent walks. The most stunning place is the World's End, a well-visited tourist attraction where the southern Horton Plains suddenly ends, with a shear precise of 1056 Meters, which is an awesome sight indeed. The return walk passes the scenic Baker Falls. This is a favourite place for trekkers, as there are plenty of soft and hard trails. Early morning visits are best, both to see the wildlife and to view World's End before mists close in during the later part of the morning.
