The best station for Sabarimala Pilgrims to alight.. One of the cleanest station. and Kottayam is a huge city compared to CNGR
so more facilities here
I was thinking Chengannur is closest
Actually closest in not CNGR or KTYM its TRVL if u know the correct path to travel.
I visited Sabarimala from Tiruvalla via a small town called Ranni. I went off season.
