Below is the general tentative plan about the places to be covered in the three day and four night trip. We arrived at this plan after taking inputs from knowledgeable persons like Devamani Rafael, Kalai Kovan, Sundar Bharatwaj, etc., The places marked in red can be covered only if time is there. Hope this plan is OK.
Feb 6th Thursday Night
Start from Chennai and reach Chidambaram by 1 AM on Feb 7th (Night halt in Chidambaram).
