Picture Paro before sunrise. The car park is dark, the air is thin and cold, a flask of tea is going round, and your flight to Kathmandu leaves at ten past seven. Everything is on time. Everything is calm. And still a small voice is asking about the flight after that one, the one home, which will not wait for anyone.
That is the real worry inside every “can we add Nepal?” question. It is not the extra country. It is the seam between two countries, and whether a mountain airport that only flies in daylight will hold it together. Seams can be planned, though. Here are the flights, the buffer and the order we would use, with a date on everything that can change.

Can you combine Bhutan with Nepal, Sikkim or Bangkok?
Yes, all three work, and the airlines have done the hard part. According to the Department of Tourism, the two national carriers connect Paro with Kathmandu, Bagdogra and Bangkok, among other hubs. Kathmandu is the easy one, Bangkok the flexible one, and Bagdogra, the airport for Darjeeling and Sikkim, is the one with a calendar attached.
We plan these joins as part of a journey, not an afterthought. Our team includes the coordinators who secure lodges in Sikkim and Darjeeling, and our journeys are designed to combine with Nepal, Sikkim or Northeast India. A Bangkok stopover is a question for us. Which lodges we would suggest for your dates is a conversation, so ask us.
If you are still choosing between countries, Bhutan versus Nepal or Japan sets out the numbers. If this is your first visit, start with planning your first trip to Bhutan, then count your travel days as carefully as you count the sights.
How do you get between them?
By air, on one of two airlines, and it pays to read the timetables closely because they move. This is what the airlines’ own autumn schedules say.
Connections, checked 30 September 2026
| Hub | Drukair, October and November 2026 | Bhutan Airlines, 15 Sep to 14 Nov 2026 |
|---|---|---|
| Kathmandu | Daily; leaves Paro at 07:10 on most days | Daily; leaves Paro at 06:50 |
| Delhi | Daily; leaves Paro at 09:40 | Daily; leaves Paro at 10:20 |
| Bangkok | Every day: nonstop on some days, via Guwahati or Bagdogra on others | Daily via Kolkata, plus nonstop on some days |
| Bagdogra | Twice a week: out of Paro Monday and Friday, into Paro Tuesday and Saturday | Not listed |
| Singapore | Three a week via Guwahati: out Monday, Wednesday, Saturday; back Tuesday, Thursday, Sunday | Not listed |
| Kolkata | Four a week; Monday and Friday stop at Gelephu | Daily, on the Bangkok flight |
Times are local, and schedules move. Drukair prints “subject to change” on its monthly PDFs, and Bhutan Airlines says its timetable may be updated every month and that it cannot be held responsible for missed connections.
One conflict to flag. Drukair’s destinations page still says twice-weekly Singapore flights, while its own October and November timetables show three each way. We trust the dated timetable, and we recheck before anything is booked.
Notice the Bangkok mornings, too. The earliest Bangkok departures to Paro are 04:10 (Bhutan Airlines) and 05:00 to 06:00 (Drukair), so a night in Bangkok before Paro can be a short one. Drukair’s Friday nonstop leaves at 13:10 and lets you sleep. Our guide to flying into Paro covers the landing itself.
How much buffer do you need?
At least 24 hours between your Paro flight and any onward flight you cannot move. The reason is Paro. The Department of Air Transport says flights there operate in visual conditions only, between sunrise and sunset, which means a low-cloud morning can hold a departure.
Book a same-day connection and you are betting on the weather. Book the next day and you are having lunch in Kathmandu, which is a much kinder bet. The buffer night also falls outside Bhutan, so it is not a night on which the US$100 per adult Sustainable Development Fee applies.
On the way in, the buffer is softer. The main Kathmandu flights leave in the morning and nothing fixed follows your arrival, so a delay costs an afternoon, not a connection. Paro sits at around 2,200 m, and our guide to altitude and health in Bhutan explains why a slow first day is time well spent. If your Nepal plans include a high trek, tell us before we order the legs.
Which country should come first?
Our lean, and it is a lean rather than a rule: fly the weather-dependent leg early and the fixed leg last. If your ticket home cannot change, put Bhutan first. A delayed Paro flight then costs you an afternoon of sightseeing, not the flight home, and your days in Nepal or Bangkok double as the buffer.
If your ticket is flexible and you want the quiet at the end, put Bhutan last and add a dedicated buffer night. Both orders work. What matters is knowing which risk you are carrying.
Sikkim and Darjeeling are different: the calendar decides. Drukair’s Bagdogra flights run out of Paro on Mondays and Fridays and into Paro on Tuesdays and Saturdays, so you either enter Bhutan on a Tuesday or Saturday, or leave it on a Monday or Friday, and build the other days around that. Kathmandu and Bangkok are happy with any day.

What changes with visas and permits on each leg?
Each country has its own door, and Bhutan’s visa opens only Bhutan’s. The Department of Tourism lists a one-off US$40 processing fee and up to five days for a correct application. On our journeys we handle the Bhutan visa and the Sustainable Development Fee for you. Bhutan’s rules have also moved lately; see what has changed for Bhutan travel.
Nepal sets its own terms. Its tourism board says that foreign nationals other than Indians need a tourist visa, which can be obtained on arrival at Kathmandu airport or from a Nepali mission beforehand, with an online form to fill in before you land.
India has its own e-Visa system and its own list of authorised entry points, so check your route against the Indian government’s portal. Any extra permits for Sikkim or Darjeeling are something we confirm for your dates, and we will not guess them here. For Thailand, check your own passport’s rules. All of this changes, so read the official pages close to departure.
What do 12-, 14- and 16-day shapes look like?
These are sketches we would draw with you, not fixed products. Our published journeys run to 6, 8 and 11 days, and the extra country is added around them. Every count below includes travel days.
- 12 days: The Soul of Western Bhutan (8 days), one buffer day, then 3 days in Kathmandu or Bangkok.
- 14 days: The same 8 Bhutan days, one buffer day, then 5 days in Darjeeling and Sikkim, with the weekday rule above deciding which way round.
- 16 days: Cranes & the Central Valleys (11 days), one buffer day, then 4 days in Nepal.
To weigh how many of those days Bhutan should get, our guide to how many days in Bhutan shows what each length gives you.
How do you choose? A three-question rule
Answer these in order and the shape usually appears.
- Which weekday can you fly? If Sikkim or Darjeeling is in the plan, the Bagdogra days fix the order.
- Can your ticket home move? If not, Bhutan goes first. If it can, decide on mood.
- What do you want to remember last? Some travellers want the prayer flags at the end. Others want a warm city and a good dinner.
Tell us the answers and the days you have, and we will draw the route with the seams marked.
Frequently asked questions
How many days do I need between Nepal and Bhutan?
None, if Nepal comes first: the main Kathmandu flights leave in the morning, and both airlines run them daily in the autumn timetables. The 24 hours matter after Paro, before a fixed onward flight.
Do I need separate visas for each country?
Yes. Bhutan’s e-visa covers Bhutan only, and Nepal and India issue their own. Tell us your route and we will point you to the official page for each leg.
Can I enter Bhutan by road from Sikkim or Darjeeling?
The Department of Tourism names Samtse, Phuentsholing, Gelephu and Samdrupjongkhar as border towns, and requires a guide for anyone who enters by land and travels beyond them. Whether the road suits your dates depends on Indian-side rules and road conditions, which we check with you. The Bagdogra flight is simpler, but it runs only twice a week.
Is a Bangkok stopover worth it?
Usually, as a full night rather than a few hours. It breaks the long-haul flight, and Drukair’s Friday afternoon departure lets you sleep. Because Bangkok has a Paro connection every day, it is also the easiest hub to fit around your dates.
