Sunauli, the border crossing between India and Nepal
The Sunauli border crossing between India and Nepal is surely one of the liveliest in the world. The customs and immigration offices flank the chaotic road that carries traffic between the two countries.
Note : Buses do not cross the border, so do not buy tickets that promise to do so. All passengers must disembark buses on one side of the border, cross the border, and join a different bus in the other country.
Money: You can change your Nepali and India rupees at the border. Approach an official money lender and agree a 1% commission charge, rather than a fix rate. The conversion rate is fixed at 1.6 Nepali rupees to Indian.
In terms of planning, it's chaos. There is no where to park a vehicle and no clear instructions or direction on the steps required to cross the border. it is a fairly efficient place though. You're likely to be through the whole process in about 2 hours.
The shops around the border sell pretty much anything you might need. There are also streets sellers who can help you out, but keep your whits about you.
The best restaurants and pretty much your only chance of finding a beer are on the Nepali side of the border. The Indian side has nothing in terms of tourist related services.
There is no real reason to stay in Sunauli, but if you do the Nepali side offers a lot more. My advice would be to keep going and not to stick around.
