My friend Guna and I left for New jalpaguri station from Kolkata in Padatik express. It costed around 350/head and took 10 hours to reach NJP. We started the trip after we met this gentleman who made our day. His name is Mr. Gopal who is the owner of Bike rental store near NJP station. Shared auto will charge Rs.10 to reach this place from NJP station. Have a look into my review Royal Rider Bike rental Google review to get a brief idea about the rental process.
Royal enfield thunderbird 350 - 1200/day
We headed towards Kalimpong(67 kms from Royal ride bike rentals) which was our first day destination.
