How to Reach Nepal from India: Flight Routes to Kathmandu for Trekkers

 

Flight routes from India to Kathmandu for trekking are more numerous and more direct than most first time trekkers expect. Because Indian citizens need no visa, the only real planning question is which city to fly from and how that connects to your chosen trek. This guide covers every practical route Indian trekkers use, by air and by land, with realistic travel times for each.

Key Takeaways

·         Direct flights connect Kathmandu with at least six major Indian cities, keeping most journeys under three hours.

·         Land border crossings remain genuinely practical for travelers from Bihar, Uttar Pradesh, and West Bengal.

·         Because there is no visa step, the airport arrival process itself is faster for Indian travelers than for almost any other nationality.

Direct Flights: The Fastest Way In

Kathmandu's Tribhuvan International Airport receives direct flights from a growing list of Indian cities, and this is the route we recommend for the overwhelming majority of trekkers, since it removes an entire day of overland transit compared to land crossings. Multiple airlines operate these routes, and frequency has increased steadily as Nepal tourism from India has grown.

Departure City	Flight Time	Typical Frequency
Delhi	1 hour 50 minutes	Multiple flights daily
Kolkata	1 hour	Multiple flights daily
Mumbai	3 hours 15 minutes	Daily
Bengaluru	3 hours 30 minutes	Several times weekly
Varanasi	1 hour	Several times weekly
Bagdogra	45 minutes	Several times weekly

 

Kolkata and Bagdogra are worth calling out specifically for trekkers heading toward Kanchenjunga in the far east of Nepal, since they cut overland transfer time significantly compared to routing everyone through Kathmandu first. Our Kanchenjunga Trek: Nepal's Most Remote High Altitude Adventure covers onward transport once you land.

Booking a route through a smaller regional airport instead of Delhi or Mumbai can save real time on connecting flights, particularly for trekkers from eastern and northeastern India. A flight from Kolkata or Bagdogra often beats a longer journey routed through a bigger hub purely because the direct distance to Kathmandu is shorter, even though these smaller airports carry less flight frequency overall and benefit from booking a little further ahead.

What Arrival Actually Looks Like for Indian Travelers

Because Indian citizens need no visa, arrival at Tribhuvan International Airport is noticeably faster than for other nationalities. You present a voter ID card or passport at immigration, clear customs, and you are done, often before travelers from visa requiring countries have finished their on arrival application. Our Nepal Trekking for Indian Travelers: Visa Free Entry, Requirements and What to Know Before You Book covers this process in full detail.

From there, permit processing for your trek begins, covered in our How to Get a Nepal Trekking Permit: TIMS, ACAP, and Sagarmatha in 2026, typically starting the same day or the next morning depending on when your flight lands.

Baggage allowance is another practical detail worth checking before you fly, since trekking gear, boots, trekking poles, and cold weather layers add up quickly. Most airlines on the India Nepal routes allow standard international checked baggage limits, but confirming this ahead of time, especially if you are also carrying rented or borrowed equipment, avoids a costly surprise at check in.

Land Border Crossings: A Practical Alternative

For travelers already near the border, or those who prefer overland travel, two crossings handle most trekker traffic. Sunauli, reached from Gorakhpur in Uttar Pradesh, connects to both Kathmandu and Pokhara by road. Kakarbhitta, reached from Siliguri in West Bengal, is the practical entry point for eastern Nepal, including Kanchenjunga region treks.

·         Sunauli, via Gorakhpur, roughly 8 to 9 hours onward to Kathmandu by road

·         Kakarbhitta, via Siliguri, the standard entry point for eastern Nepal and Kanchenjunga

·         Both crossings involve the same voter ID or passport check as air arrival, no visa required

Land crossings make the most sense when combined with a wider regional trip. Our India itineraries page has ideas for building an overland Nepal leg into a longer journey through northern India.

Land crossings also involve a currency consideration air travelers skip. Money changers at the border offer reasonable rates for converting Indian rupees, though since the currencies are pegged, this matters less than it would elsewhere. Still, carrying some Nepali rupees before you reach the crossing itself speeds up onward transport arrangements on the Nepal side.

Choosing a Route Based on Where You Are Trekking

Your entry point should match your trek, not just your home city. Everest Base Camp and most central Nepal routes, including Langtang, are best reached by flying into Kathmandu directly. Our Everest Base Camp Trek: Complete Itinerary, Cost, and Difficulty Guide and Langtang Valley Trek: A Short, Scenic Himalayan Adventure Near Kathmandu both assume a Kathmandu arrival.

Manaslu and Upper Mustang, covered in our Manaslu Circuit Trek: The Ultimate Off the Beaten Path Alternative to EBC and Upper Mustang Trek: Exploring Nepal's Forbidden Kingdom, also start from Kathmandu, with the trailhead reached by a separate domestic transfer after you land.

Our itineraries page lists arrival guidance for every region we operate in, worth a quick check alongside the specific trek pages above once your route is decided.

Timing Your Flights Around the Trekking Season

Flight prices and availability shift with Nepal's peak trekking seasons, spring from March to May and autumn from September to November. Our Best Time to Trek in Nepal: A Month by Month Guide is worth checking before booking flights, since both fares and seat availability from major Indian cities tighten during these windows.

The Nepal Tourism Board publishes visitor arrival statistics by month, and the seasonal pattern for Indian travelers tracks closely with these peak windows, so booking flights a few weeks ahead during March, April, October, and November is worth the extra effort compared to shoulder season travel.

One last consideration for group trips. If your trekking party is flying from different Indian cities, it is worth coordinating arrival times rather than each booking independently, since your agency typically arranges a single airport pickup and a shared start to permit processing. A gap of more than a few hours between the first and last arrival can push your first trekking day back, particularly on itineraries with fixed departure dates for restricted regions.

Plan Your Route to Kathmandu

Whether you fly direct, connect through Delhi, or cross overland from the border, the process from there is the same for every trekker.
