The hills of Kolukkumalai in Kerala are home to the highest tea plantations in the world and the tea grown here has a special flavour and freshness due to the high altitude. This tea estate is about 7,900 ft above sea level and one can have some excellent views of the far off plains in the bordering state of Tamil Nadu. The sprawling plantations and an old tea factory lend an old world charm to this place, the two-storied building, built in the 1930s, with its wooden interiors and aroma would present you some time-tested methods of tea processing. Here tea is processed in the traditional method, which is different from the more popular CTC (crush-tear-curl method). Kolukkumalai is about 38 km from Munnar and the hill top is accessible only by jeep.
