Fly from Mumbai to Kathmandu
Mumbai and Nepal aren't connected by road in any way that makes practical sense for a holiday, so flying is the option most travellers choose. Direct flights connect Mumbai with Kathmandu, and the flight itself takes a little over two hours.
Airlines including IndiGo and Air India operate on this route. Flight availability and fares can change through the year, so it's best to check the current options for your travel dates before booking.
