Sometimes it may be half n hr delay not all time. From madurai you have to get auto and travel arapalayam busstand 5 kms and you will get TNSTC GOVT bus to kodaikanal every 40 mins interval. Travel time 3 hrs. Or you can get down in dindigul from there 3 hrs but first bus around 5:30. but station has no ameneties but madurai is best
