Getting there & away
The Terai is easily accessible from Kathmandu and Pokhara in Nepal and from West Bengal, Bihar and Uttar Pradesh in India. The Indian rail network passes close to several of the most important border crossings and there are frequent bus and air connections from the Terai to towns and villages across Nepal.
The Sunauli crossing is by far the most popular route between the two countries, but immigration staff are used to seeing foreign tourists at all the crossings and Nepali visas are available on arrival. You need one passport photo and US dollars cash for the visa fee (currently US$30 for a single entry visa and US$80 for multiple entry).
Royal Nepal Airlines Corporation(RNAC; www.royalnepal.com) and many private airlines offer flights around the Terai. Currently, you can fly from Kathmandu or Pokhara to Nepalganj, Biratnagar, Bharatpur, Bhairawa, Janakpur, Simara (for Birganj) and Bhadrapur (for Kakarbhitta) - see these individual towns for details.
