Travel Tips

BY RAIL: Take the Howrah Raxaul Mithila Express and disembark at Raxaul. That is the farthest point by rail on the Indian side of the border. Nepal is just a short distance away by road. Or take any train from Howrah or Sealdah or Kolkata which stops at New Jalpaiguri or Siliguri or Haldibari. Nepal is a short distance by road from these points. Kamrup Express, Darjeeling Mail, Kanchanjungha Express, Kanchan Kanya Express, Teesta Torsa Express and Uttar Banga Express are some of the trains that pass through New Jalpaiguri.
BY ROAD: Take any NBSTC, SBSTC, CSTC or private buses leaving from Esplanade in Kolkata for Siliguri. Siliguri is a short distance away from Nepal by road.
People of Kolkata are warm and friendly. Ask anybody when you need help and remain assured of the best possible assistance. You are assured of similar behaviour in other parts of West Bengal too.
