The green mountains of South India, mostly covered with tea plants never fail to refresh your mind just like a cup of tea does.
Day 1 though starts from a much crowded city of Coimbatore. Reach Coimbatore by train or flight whichever convenient. The journey by train is better as it takes you through the mountains and not above them!
Explore Coimbatore's malls, markets, museums, the adiyogi statue etc and get a good sleep!
