Getting there from Kolkata
Paro is Bhutan's international gateway and the only airport most visitors use. From Kolkata the flight is short, about an hour in the air, which makes it one of the quickest foreign trips from the city. Capacity is limited: a small number of rotations each week, with schedules adjusted by season and demand. Routes have been suspended and restored before, so confirm the current timetable with the airline before building a plan around a particular day.
The alternative is overland, through the border town of Phuentsholing in West Bengal's north, reached by a long road journey via Siliguri. It takes a full day or more and suits travellers already heading to the Darjeeling hills. Indian citizens can cross at the land border with a permit; other nationalities need to clear entry formalities in advance. Check road conditions and border timings with the Department of Immigration of Bhutan closer to travel.
- Paro flights: A short flight, but limited seats and few weekly rotations, so book well ahead and recheck the schedule.
- Overland via Phuentsholing: A long road trip through north Bengal that takes at least a full day and suits travellers combining the hills.
- Weather on approach: The mountain approach means cloud can delay or cancel landings, so keep the first and last days loose.
Choosing between Paro and Thimphu
Paro sits in a wide valley of fields and wooden farmhouses, with the dzong, the national museum in the old watchtower and the climb to Taktsang, the Tiger's Nest monastery, as the main draws. The monastery hike takes most of a morning and involves steep stone steps. Paro is also the base for day walks and for the road to the capital. Dress modestly at dzongs and monasteries, and check before photographing interiors.
Thimphu is the capital, roughly an hour by road from Paro, and holds the seat of government, Tashichho Dzong, the large Buddha Dordenma statue on the hillside, the textile museum and a weekend market. It is a working city rather than a shrine-and-view destination, and a day or two covers the centre. Many trips combine both, arriving at Paro and driving straight to Thimphu or the reverse, with flight dates setting the order.
When to go
Spring, from March to May, and autumn, from September to November, bring clear skies, mild days and the best conditions for walking. Winter is cold, with sharp mornings and clear views of snow on the high ridges. The monsoon, roughly June to September, brings heavy rain, cloud sitting in the valleys and a risk of landslides closing mountain roads. Rainfall is heaviest in July, when trails are at their muddiest.
Festival dates follow the Bhutanese lunar calendar and move each year; each district holds its own tsechu, so check the current year's dates with the Tourism Council of Bhutan before fixing a route around one. Book accommodation early for those weeks. Kolkata's own festival season, from Durga Puja to Christmas, is when flights out are fullest, so plan both ends of the trip together.
Practical tips
Indian citizens do not need a visa but must obtain an entry permit and pay the Sustainable Development Fee. Other nationalities arrange a visa in advance, usually through a licensed operator. Carry a passport with sufficient validity and printed copies of approvals. Rules, fees and permit durations change, so confirm with the Department of Immigration of Bhutan shortly before departure.
Indian notes circulate alongside the Bhutanese ngultrum, which is pegged at par. Cards work in hotels and city restaurants; carry cash for villages, roadside stalls and smaller hotels, and use ATMs in Thimphu and Paro rather than relying on machines elsewhere. Book rooms and transport well ahead around Durga Puja, Diwali and Christmas, when demand from Kolkata peaks, and again for tsechu weeks.
- Documents: Carry a passport, printed permits and proof of Sustainable Development Fee payment, and check current requirements with Bhutan's Department of Immigration.
- Cash and cards: Cards work in the cities but villages run on cash, so withdraw in Thimphu or Paro before heading further out.
- Festival weeks: Rooms fill for tsechu dates and for Kolkata's Puja and Christmas holidays, so reserve flights and hotels early.
- Slow roads: Mountain roads wind and journeys take longer than the map suggests, so allow slack in each day's plan.

FAQ
Do Indian citizens need a visa for Bhutan from Kolkata?
No visa is needed for Indian citizens, but an entry permit is required, along with payment of the Sustainable Development Fee. Carry a passport or voter card as identity. Permit rules and the fee are revised from time to time, so check the Department of Immigration of Bhutan before flying from Kolkata.
How long is the flight from Kolkata to Bhutan?
Paro is about an hour's flying from Kolkata, the shortest international sector from the city. Services are limited, with few rotations in a week and changes between seasons. Confirm the current schedule with the airline before fixing dates, and allow for weather delays on the mountain approach.
Can you travel from Kolkata to Bhutan overland?
There is no direct train. The road route runs through north Bengal to Phuentsholing, the border town, and takes a full day or more via Siliguri. Indian citizens can obtain a permit at the border; other nationalities must clear entry formalities in advance. Check border timings with the Department of Immigration of Bhutan.
Should you choose Paro or Thimphu on a Bhutan trip from Kolkata?
Paro suits walkers and first-time visitors, with the valley, the dzong and the Taktsang monastery hike. Thimphu is roughly an hour away by road and covers government buildings, museums and city life. Most itineraries combine both, and short flight schedules often decide the order rather than preference.
When is the best time to visit Bhutan from Kolkata?
March to May and September to November give clear skies and mild walking weather. December to February is cold but bright, with snow on high passes. The monsoon, roughly June to September, brings rain and landslide risk on mountain roads. Festival dates follow the lunar calendar, so check the current year's dates with the Tourism Council of Bhutan.
How much time should a Bhutan trip from Kolkata allow?
Plan around the flight dates rather than a fixed number of nights. A short trip can cover Paro alone, while adding Thimphu and a longer valley needs more days. Mountain roads are slow and weather can change a plan, so keep the first and last days light.
What money should you take to Bhutan from Kolkata?
Indian notes circulate alongside the Bhutanese ngultrum, which is pegged at par. Cards work in hotels and city restaurants, but villages, roadside stalls and smaller guesthouses run on cash. Withdraw in Thimphu or Paro before heading further out, since machines elsewhere are few.
Is it necessary to book ahead for Bhutan during Durga Puja?
Yes. Kolkata's festival season from Durga Puja to Christmas is when demand from the city peaks, and Bhutan's own tsechu weeks fill rooms in Paro and Thimphu. Flights have few seats to begin with. Reserve flights, rooms and any guided walking well in advance, and recheck permits close to departure.
What should you check before flying from Kolkata to Paro?
Confirm the permit or visa position with the Department of Immigration of Bhutan, check that the Sustainable Development Fee is settled where required, and verify the flight schedule with the airline. Carry printed approvals, a passport with enough validity, and layers for cold mornings. Weather on the mountain approach can delay landings.
