Nepal by Road or Flight from India?
The road-versus-flight decision changes the entire trip. Road makes sense from nearby Indian gateways, for larger groups, and when Lumbini/Chitwan/Pokhara form part of a continuous route. A direct flight to Kathmandu is usually stronger for short trips from Delhi, Mumbai and other distant cities. The best itinerary starts by solving this transport question first.
Choose road when
The route itself links useful destinations—such as Lumbini, Chitwan and Pokhara—and the starting city is close enough to Nepal for the road day to remain sensible.
Choose flight when
Your holiday is short, Kathmandu is a major focus, or you are starting from Delhi/Mumbai/another distant city where overland travel would consume too much time.
Hybrid itineraries
Some of the best journeys mix a flight with local private transport rather than insisting on one mode for the entire holiday.
