I wanna go to goa from manglore by bike with my friend so which rout suite me best although am a crazy rider?

Goa is very far from mangalore. I dont know which route will suite you. You should go by that route which you know perfectly. But i would suggest you go by bus or train. It would be comfortable for you. Travelling by bike on a long route could be risky. Bt life is full of risk and adventure so enjoy the trip.
