Want to take a side trip from India to Nepal? It's a popular thing to do and there are a number of ways to go about it, depending on how much money you're prepared to spend. This guide outlines the best options for travel, as well as information about that troublesome two month gap rule on Indian tourist visas.
If you want to fly, Delhi to Kathmandu is the least expensive route by air to Nepal. Otherwise, the best option is to take a train and then a bus.
Many people travel overland from Varanasi to Kathmandu, either by bus, or train and bus combination. It takes less time than overland from Delhi. It's also possible to fly. However, it's much costlier than from Delhi, although it takes around the same time.
Most people going overland from India to Nepal pass through the Sunauli border. It's not at all appealing there, so you'll want to make your way onwards as quick as possible.
You may have heard that you must stay out of India for at least two months between visits, even if you have a multiple entry visa. However, an exception to the two month gap rule is possible if you're traveling to a neighboring country, such as Nepal. There are a few things you need to know about it though.
