With a population of nearly 170,000, Biratnagar in the second largest city in Nepal, and it is located near the Terai on the south-eastern border with India.
A flight from Kathmandu (290km) takes 40-45 minutes if there isn't any air traffic, and single tickets cost about $220 for foreigners and around 2860Rs for nationals on Domestic Airlines. air viva offers several direct flights between Biratnagar and Tumlingtar.
By bus it may take 10-13 hours of time for about NRs-700-900($9-14). There are two ways in travelling in bus one is in day and other in night. In comparision to day, night buses are safe to travel because at night there are no strikes or road blockades. While travelling by bus one can witness the beauty of various scenes that are missed by aeroplane. It's good to take food of your own because the restaurants the bus stops at on the way serve bad quality food at extremely high prices, having made an arrangement with the driver, who gets paid.
Rickshaws are a good option within the city, and walking is easy between most places. Expect to pay about 20 rupees km for a rickshaw depending on how many people you are or if you have a lot of cargo. There are no official taxi services, but taxis are easily available at the airport, near Mahendra chowk, and from major hotels. There are tampoo's (auto-ricksaws) around the city which are often cheaper than other transportation options. Buses aren't used frequently in the urban centre.
There are a number of ATMs in Biratnagar. Ask locals for the closest, but make sure to ask more than one as people occasionally misdirect you.
For groceries there is now a supermarket near (ex-) Mahendra chowk.
Again, ask locals for nearby restaurants or "hotels". Be aware that these often close early, and by around 9pm you might struggle to find something nearby.
You can find something clean and friendly from 300 RP per person per night if you ask around. Be aware of inflated prices for foreigners - these are often very negotiable. There are also a few internationally priced hotels, at slightly more than you would pay in Kathmandu for slightly poorer quality.
