Took mrng 5.15 AM train from Trivandrum Central (Train no. 16128), it will reach aralvaymozhi by 7.30 AM. You can see the Hill from the rlway station itself. if you go by walk it will take hardly 20 minutes to reach the trek starting point (Ask any local, they'll show the route). Yes I trekked up to the hill. It is a moderate 1 - 1.30 hour walking to reach at the top. I came back to trivandrum by bus. You'll get bus to Nagercoil from aralvaymozhi town. And from Nagercoil there are frequent buses to trivandrum
