Delhi to Kathmandu Flight Guide 2026: Tips & Fares

The Delhi–Kathmandu route is one of the most underrated quick-getaway options for Indian travellers. At 75 minutes in the air and no visa requirement, Kathmandu is arguably easier to visit than many Indian domestic destinations. Yet Nepal consistently delivers experiences that feel genuinely foreign — the Himalayan skyline visible from the valley, medieval temple squares that survived centuries, and trekking routes that rank among the world’s finest.

This guide covers everything specific to the DEL–KTM flight — airlines, current fares, what documents to carry, Tribhuvan Airport arrival tips, Kathmandu highlights, the best travel season, and practical tips for Indian travellers making the trip in 2026.

Do Indians Need a Visa for Nepal in 2026?

No. Indian passport holders enjoy completely visa-free entry into Nepal under the 1950 Treaty of Peace and Friendship between India and Nepal. There is no fee, no application process, no time limit, and no prior approval needed. Indians are treated as domestic visitors under Nepali immigration law — the only international travellers with this privilege (Government of Nepal Department of Immigration, 2024).

What Documents Do You Need?

This is where many Indian travellers get caught off guard. You cannot fly to Kathmandu on an Aadhaar card alone. The accepted documents at Tribhuvan International Airport (KTM) for Indian nationals are:

• Valid Indian passport — the universally accepted option. No minimum validity requirement is mandated for Indians, though 6 months remaining is advisable for general travel safety.
• Valid Voter ID card (Election Commission of India) — accepted at the Nepal border and at KTM airport for Indian nationals.
• Not accepted: Aadhaar card alone, driving licence alone, or PAN card alone.

[PERSONAL EXPERIENCE] We’ve seen travellers turn up at Delhi’s IGI Airport for their KTM flight with only an Aadhaar card, expecting it to suffice. It doesn’t. IndiGo and Air India check-in staff at DEL will not board you without a valid passport or voter ID. If you’re a frequent traveller, the passport is always the safest choice — it’s accepted everywhere, including for any extensions of your Nepal trip into Bhutan or Tibet if you plan onward travel.

Nepal Currency Note Restriction

Indian currency is accepted across Nepal, but there’s one important restriction: Indian Rupee notes of INR 2,000 denomination are not accepted in Nepal (Nepal Rastra Bank regulation). Carry INR 500 and INR 100 notes. The exchange rate is fixed at NPR 1.6 per INR 1 — you’ll often find it easier to just use Indian notes directly at shops and restaurants in Kathmandu.

Delhi to Kathmandu Flight — Airlines, Schedule, and Fares

The DEL–KTM route is served by multiple carriers with several daily departures. The 75-minute flying time makes it one of the most convenient international routes from India — you can legitimately do a morning departure and be at your Kathmandu hotel before lunch. (Nepal Tourism Board, 2024)

Airlines on the DEL–KTM Route

IndiGo typically offers the lowest base fares on this route. During off-peak months (February, June, August), return fares from Delhi can dip below INR 8,000. During the peak October–November trekking season and Dashain festival period, fares can spike to INR 18,000–25,000 — book 6–8 weeks ahead if you’re travelling then. Search current DEL–KTM fares on HappyFares and set a fare alert if your dates are flexible.

Flight Timing Tips

Morning departures from Delhi (6–9 AM) arrive in Kathmandu before midday, giving you a full afternoon to explore. Avoid late-evening arrivals if this is your first visit — Tribhuvan Airport road to central Kathmandu can be congested, and arriving in daylight makes the initial orientation much easier. The approach into KTM through the Himalayan foothills is spectacular — window seats on the left side of the aircraft (A-side) typically offer better mountain views on the descent.

Tribhuvan International Airport — Arrival Tips for Indians

Tribhuvan International Airport (KTM) is Nepal’s only international airport and handles all flights to Kathmandu. It’s a single-terminal facility — functional, but not as slick as major Indian airports. Knowing what to expect on arrival saves time and avoids confusion.

Step-by-Step Arrival Process for Indians

1. Disembark and follow signs to Immigration. The walk from gate to immigration is short — about 5 minutes.
2. Indian nationals queue: Look for the “SAARC Nationals” or “Indian Nationals” queue — it moves faster than the general international queue since no visa stamping is required.
3. Immigration desk: Present your passport or voter ID. The officer will stamp your entry. No forms to fill, no fees.
4. Baggage claim: Carousels are immediately after immigration. Allow 15–20 minutes for bags on a typical flight.
5. Customs: Standard declaration process. Most tourists walk through the green channel without inspection.
6. Exit to arrivals: You’ll be met by taxi touts immediately outside. Pre-arranged hotel pickups are also possible — your hotel can arrange a fixed-fare transfer.

Getting from KTM Airport to Kathmandu City

The airport is 6 kilometres from Thamel, Kathmandu’s main tourist hub. Options:

• Pre-paid taxi: Available at a counter inside arrivals. Fixed fare to Thamel is approximately NPR 700–900 (INR 440–565). This is the recommended option — avoids negotiation and informal drivers.
• Hotel pickup: Most hotels in Thamel offer airport pickup for NPR 800–1,200 (INR 500–750). Worth arranging in advance, especially for late arrivals.
• Informal taxis: Available immediately outside the terminal. Always agree on the fare before getting in. Expect NPR 800–1,200 to Thamel without metering.
• Pathao/InDrive apps: Ride-hailing apps operate in Kathmandu. Download before arriving — they offer transparent pricing and are reliable from the airport.

Kathmandu Highlights — What to See and Do

Kathmandu Valley holds three UNESCO World Heritage Sites within easy reach of each other — Kathmandu Durbar Square, Pashupatinath Temple, and Boudhanath Stupa. The density of genuinely extraordinary sights within a compact area is rare anywhere in the world.

1. Pashupatinath Temple

One of the most sacred Shiva temples in the world, Pashupatinath sits on the banks of the Bagmati River and is among Hinduism’s most important pilgrimage sites outside India. The main temple is open only to Hindus, but the surrounding ghats — where cremation ceremonies take place openly on the riverbanks — are accessible to all and offer a profoundly moving experience. The complex is 3 kilometres from Thamel. Entry for foreign nationals (including Indians) costs NPR 1,000 (INR 625).

2. Boudhanath Stupa

One of the largest Buddhist stupas in the world, Boudhanath is the spiritual centre of Tibetan Buddhism outside Tibet. The massive white dome, topped by a gilded tower painted with the watchful eyes of the Buddha, is surrounded by monasteries, spinning prayer wheels, and monks in crimson robes. The best time to visit is early morning or evening when the circumambulation circuit fills with devotees. Entry costs NPR 400 (INR 250).

3. Kathmandu Durbar Square

The old royal palace complex in the heart of old Kathmandu is a UNESCO site, though it suffered significant damage in the 2015 earthquake. Reconstruction is ongoing and impressive. The Kumari Ghar — the living quarters of Nepal’s Living Goddess — faces the square. The Goddess occasionally appears at the window. The surrounding streets are dense with wood-carved temples, courtyards, and traditional Newari architecture. Entry: NPR 1,000 (INR 625) for foreign nationals.

4. Swayambhunath (Monkey Temple)

This ancient Buddhist stupa sits atop a steep hill west of the city, offering panoramic views of the Kathmandu Valley. The 365-step climb up the eastern staircase is flanked by hundreds of monkeys — bold and entertaining, but watch your belongings. Entry: NPR 200 (INR 125). Best visited early morning for the views and fewer crowds.

5. Thamel — the Traveller’s Hub

Thamel is Kathmandu’s tourist district — a maze of narrow lanes packed with trekking gear shops, restaurants, bookshops, handicraft stores, and rooftop cafes. It’s touristy by definition, but genuinely lively. This is where to stock up on gear if you’re trekking, find a cooking class, or simply spend an evening over momos and Nepali chai. Many items here are cheaper than equivalent quality goods in Indian cities.

Best Season to Visit Kathmandu

Kathmandu sits at 1,400 metres altitude, which gives it a temperate climate distinct from Nepal’s lowland Terai region. The weather is a key factor in planning your visit, especially if you’re combining Kathmandu with trekking in the Himalayas (Nepal Tourism Board, 2024).

• October–November (Peak — Best for Trekking): Crystal-clear skies, Himalayan views from Kathmandu Valley, temperatures of 10–25°C. Dashain and Tihar festivals fall here — Kathmandu is spectacular during these periods. This is the most popular season for Indian tourists. Book well in advance.
• March–April (Second Best): Spring season. Rhododendron forests in the hills are in full bloom. Good mountain views. Holi and other spring festivals add to the atmosphere. Slightly warmer than October–November but very pleasant.
• December–February (Winter — Cold but Quiet): Temperatures in Kathmandu drop to 2–8°C at night. Clear skies and excellent mountain views. Very few tourists, lowest hotel rates, lowest flight fares. Good for city sightseeing but too cold for high-altitude trekking without proper gear.
• June–August (Monsoon — Avoid for Trekking): Heavy rainfall, leeches on hiking trails, and frequent flight delays and cancellations due to poor visibility. Kathmandu city sightseeing remains possible, but trekking routes are difficult. Fares are at their lowest.

[UNIQUE INSIGHT] The window between Dashain (late October) and Tihar (early November) is genuinely one of the best times to be in Kathmandu. The city is festive, locals are in traditional dress, and the Himalayan views after monsoon clearing are at their sharpest. But flight prices spike significantly — expect to pay 40–60% more than off-peak fares during this exact window.

Practical Tips for Indian Travellers Flying to Kathmandu

• Carry voter ID or passport — not just Aadhaar. This cannot be stressed enough. Check-in staff at Delhi airport will not board you without a valid document.
• Currency: Indian Rupees are accepted at most Kathmandu shops and restaurants at NPR 1.6 per INR 1. ATMs in Thamel dispense Nepali Rupees — most accept Indian debit cards. Avoid airport exchange counters.
• Altitude: Kathmandu is at 1,400 metres — high enough that some travellers experience mild headaches on the first day. Stay hydrated, avoid alcohol on arrival day, and take it easy for the first 24 hours if you’re not acclimatised.
• SIM card: Nepal Telecom and Ncell offer tourist SIMs at the airport. 10 GB data for 30 days costs approximately NPR 500 (INR 312). Bring a passport copy — SIM registration requires identity verification.
• Power sockets: Nepal uses a mix of Type C, D, and M sockets. Indian plugs (Type D/M) usually work directly without an adaptor.
• Air quality: Kathmandu’s air quality can be poor, especially March–May before monsoon rains. Carry a light mask if you’re sensitive to dust and pollution.
• Tipping: Not mandatory but appreciated. INR 50–100 or NPR 100–200 is a reasonable tip for restaurant service and guided tours.

Frequently Asked Questions

Do Indians need a visa for Nepal in 2026?
