We visited Kolukkumalai in August 2017.
We had stayed in “Sterling Munnar Terrace Green resort”. We started our journey to Kolukkumalai from the resort (lot of jeeps available in front of this resort) in a Jeep.. Kudos to Mahindra.. Yet again another route which proves the power and performance of a Mahindra Jeep. It is about one and a half hour journey . The hill top village is accessible only by such jeeps due to rugged and rain drenched roads covering up to 17 km. Its really a jumpy Bumpy ride which you will enjoy. Overall you might need 6-7 hours for the entire Kolukkumalai (To and Fro) trip. The jeeps can carry 6-7 People at a time.
Jeep Safari Charges: Seems its a fixed amount of Rs. 2000. We drive through the town of Suryanelle and then onto tea plantations owned by Harrisons Malayalam Ltd. through which a narrow, stony and rocky road with numerous hairpin bends leads to Kolukkumalai.
The tea estate views are quite refreshing.
On top of the hill, you can visit the Oldest tea factory established in 1930 by a Scottish planter. One can easily understand the various different processes that are used to create exotic varieties of Munnar tea at the factory.
One Line Summary: If you are planning a Munnar trip, never miss this place. This is indeed a lifetime experience and its a must visit place. Highly recommended to all fellow travelers.
