Bhutan is one of the few places that works beautifully as a multi-generational family trip — it is peaceful, spiritually meaningful, and not the kind of destination where you spend your time at amusement parks. The catch is altitude, which matters more for elderly parents than it does for younger adults, and the small detail that Paro airport is one of the trickiest approaches in commercial aviation.
TL;DR — what you need to know first
Kolkata (CCU) is the closest Indian city to Paro and typically has the most convenient flight connections to Bhutan. Only two airlines fly into Paro International Airport — Druk Air (Royal Bhutan Airlines) and Bhutan Airlines. Fares are regulated and not cheap — typically in the range of USD 200–350 per person one-way from Kolkata as of 2026 (verify current fares on the airlines' sites or through authorised agents). Paro sits at around 2,235 metres; Thimphu is at about 2,320 metres. Elderly travellers with heart conditions, hypertension, or respiratory issues should consult their cardiologist or physician before this trip — altitude effects can manifest within 6–24 hours of arrival. A gradual acclimatisation plan makes the difference between a memorable holiday and a medical emergency.
Flying to Paro: Druk Air vs Bhutan Airlines from Kolkata
Paro International Airport (PBH) is served by exactly two carriers globally — Druk Air (the national carrier) and Bhutan Airlines (a private carrier). Both are small fleets operating ATR72 turboprops and Airbus A319/A320 jets depending on the route. From Kolkata (CCU):
- Druk Air (Royal Bhutan Airlines): Operates regular services from CCU to PBH. Druk Air also serves Delhi (DEL), Mumbai (BOM), Guwahati (GAU), and several other cities — Kolkata is one of their better-connected Indian ports. The airline is full-service by Bhutanese standards, which means a meal and checked baggage are typically included. Service is professional and the aircraft are well-maintained. Druk Air fares are not cheap — they are set under a regulated framework, and the airline is essentially a monopoly/duopoly with Bhutan Airlines.
- Bhutan Airlines: A smaller private carrier that has periodically run Kolkata–Paro services. Their schedule has been less consistent than Druk Air — check their current timetable directly at bhutanairlines.bt or through an authorised ticketing agent. Fares are broadly comparable to Druk Air's.
Booking tips: Neither airline is easily bookable through Indian OTAs like MakeMyTrip or Cleartrip — you may need to book directly on the airline websites or through a Bhutan-licensed tour operator. If you are booking through a FlightGPT Partner agent, they may have GDS access to Druk Air inventory, which can simplify the booking process for a multi-city family trip. The Bhutan Sustainable Development Fee (SDF), currently USD 100 per person per night (Indian nationals have a different, lower rate — verify on the Tourism Council of Bhutan website as this has been revised), is not included in the flight fare and is paid separately to your tour operator.
Flight time from Kolkata to Paro is about 90 minutes. The scenic flight, approaching through the Himalayan foothills and then the mountains themselves, is an experience in its own right — on clear days you can see mountain ranges including Kanchenjunga from the eastern side. Book window seats on the left side of the aircraft (flying into Paro) for the best views.
Paro's famous approach: what to expect (and reassure elderly parents about)
Paro airport has a reputation as one of the world's most difficult airports. This is accurate but not alarming — the approach involves flying through a mountain valley at low altitude, making tight turns around the terrain, and landing on a relatively short runway. Only a handful of specifically certified pilots are authorised to land at Paro. The aircraft does bank quite sharply during the approach and the views out the window are spectacular and slightly heart-stopping simultaneously.
For elderly family members who are nervous flyers, brief them in advance: the approach looks more dramatic than it feels. The aircraft banks, you see mountains very close out the window, and then you are suddenly on the runway. It is a normal certified procedure, not an emergency. What is not normal is the runway elevation (2,235 metres) — at that altitude, ear pressure equalisation after descent can take a few minutes longer than at sea-level airports. Anyone with recent ear surgery or active sinus issues should consult a doctor before the trip.
Weather diversions: Paro operates under visual flight rules, meaning poor visibility or cloud cover in the valley can delay or divert flights. Diversions to Bagdogra (IXB) or Guwahati (GAU) have happened. Travel insurance that covers missed connections and hotel diversions is worth having. This is not a frequent occurrence, but it is a known risk specific to Paro — factor it into your itinerary with a buffer day if possible.
Altitude and elderly parents: the medical reality
Thimphu and Paro are both at around 2,300 metres — roughly the altitude of Shimla or the top of the Rohtang Pass in Himachal Pradesh. Most reasonably healthy elderly adults adapt to this fine, especially if they are not rushing around. The issues arise with:
- Existing cardiovascular conditions: High altitude reduces oxygen availability, which increases the heart's workload. For elderly parents with controlled hypertension, coronary artery disease, or heart failure, this requires a pre-trip cardiology consultation. The doctor may adjust medications (some blood pressure drugs behave differently at altitude) and should advise on warning signs.
- Chronic respiratory conditions: COPD, asthma, and sleep apnoea patients are at higher risk for altitude effects. A respiratory physician's clearance is advisable.
- Acute Mountain Sickness (AMS): Symptoms include headache, nausea, fatigue, and dizziness. AMS can affect anyone regardless of fitness, but elderly travellers may take longer to recover. The standard acclimatisation advice — go slow, stay hydrated, avoid alcohol and heavy meals in the first 24–48 hours — applies doubly for older adults.
Practical acclimatisation plan for a multi-generational group:
- Day 1: Arrive in Paro, check in, rest. Do not schedule any sightseeing. A short walk around the guesthouse or hotel grounds is enough. Light dinner. Early bedtime.
- Day 2: Gentle walking in Paro town and the nearby Paro Dzong. Avoid the Tiger's Nest hike until day 3 at the earliest, and even then only if elderly parents are clearly comfortable. Hydrate consistently — altitude suppresses thirst.
- Day 3: If everyone is well-acclimatised, Thimphu is at essentially the same altitude (slightly higher, 2,320m) and is a manageable half-day drive away. Plan Thimphu for day 3–4.
- Days 4–5: Punakha, which is at around 1,200 metres — lower than Paro/Thimphu. This is intentional: dropping altitude after the first 2–3 days is actually a relief and elderly parents will feel markedly better there. Punakha also has the most beautiful dzong in Bhutan and the river confluence, which is spectacular.
Medications: Acetazolamide (Diamox) is sometimes used prophylactically for altitude. It requires a prescription and is not appropriate for everyone (sulfa allergy, kidney conditions). Discuss with a physician before travel — do not self-prescribe. Carry a basic medical kit with paracetamol, ORS sachets, and a pulse oximeter. Pulse oximeters (cheap and widely available on Amazon and Flipkart) are genuinely useful to monitor blood oxygen saturation: a reading consistently below 90% at rest warrants medical attention.
A family-safe Bhutan itinerary: 6–7 days
Bhutan's Tourism Council requires most visitors to book through a licensed Bhutanese tour operator — independent travel has become more accessible in recent years but tour operator packages remain the standard route. The itinerary below is designed for a mixed-age family group including elderly parents:
Days 1–2: Paro. Arrive, rest. Visit Paro Dzong (flat grounds, elderly-friendly). The National Museum of Bhutan near Rinpung Dzong has good exhibits on Bhutanese culture and history — a few stairs but manageable with slow walking. The Paro valley itself is beautiful and the town is small enough to walk comfortably.
Days 3–4: Thimphu. Drive (1.5 hours on a scenic mountain road). Thimphu's Tashichho Dzong is the grandest administrative dzong in Bhutan and a remarkable sight. The weekend market is worth a morning. The National Memorial Chorten (a large stupa in the city centre) is elderly-friendly — flat paved area, easy to circumambulate slowly. Avoid cramming too much into each day.
Day 5: Punakha. Drive from Thimphu over Dochula Pass (3,100m) — this is the highest point on the standard itinerary and worth a slow stop (check elderly parents are comfortable at this elevation; it is just under 2 hours and involves a pass crossing). Punakha is at 1,200m and feels noticeably warmer and easier to breathe. Punakha Dzong at the confluence of the Pho Chhu and Mo Chhu rivers is the most photogenic in Bhutan. Optional: the suspension bridge to the dzong is gentle.
Days 6–7: Tiger's Nest (Paro Taktsang) option. The famous clifftop monastery is a 4–5 hour hike (steep, around 900m elevation gain) from the valley floor. This is achievable for fit adults, but not recommended for most elderly travellers or those who showed any AMS symptoms in the first few days. Horses are available for the lower section (to a viewpoint at about halfway), which elderly parents can use to see the monastery from a stunning vantage point without the full hike. The horse option plus a return on foot at leisure takes 3–4 hours. A genuinely good compromise for mixed-age groups.
Money, insurance, and booking practicalities
Bhutan uses the Bhutanese Ngultrum (BTN), which is pegged 1:1 to the Indian Rupee. Indian Rupee notes (except ₹2,000 notes, which are now demonetised) are accepted everywhere in Bhutan — for Indian travellers, this effectively means you do not need to carry a foreign currency at all for small daily expenses. ATMs in Thimphu accept international Visa and Mastercard. Bhutan is a cash-heavy economy outside hotels; carry sufficient notes for tipping, small shops, and monastery donation boxes.
The SDF (Sustainable Development Fee) and tour package costs are typically paid in USD through your licensed tour operator before arrival. Indian nationals have historically paid a lower or zero SDF compared to international visitors — verify the current rate on the Tourism Council of Bhutan website (tourism.gov.bt) as this structure has been updated in recent years.
Travel insurance: given the altitude risk for elderly parents and the weather-diversion possibility at Paro airport, comprehensive travel insurance is genuinely important for this trip. Look for a policy that covers altitude sickness, medical evacuation, and trip disruption. Tata AIG, Bajaj Allianz, and ICICI Lombard offer policies with medical evacuation cover — compare and verify the terms for high-altitude travel before purchasing. A medical evacuation from Bhutan to India is expensive without insurance.

Bottom line
Bhutan rewards careful planning, especially for multi-generational groups. The altitude is real but manageable with a sensible itinerary — the Paro–Thimphu–Punakha circuit is almost perfectly designed for acclimatisation because Punakha's lower altitude gives everyone a chance to breathe out. The Tiger's Nest viewpoint (via horse) means elderly parents do not have to miss the iconic sight; they just experience it at a gentler pace. Sort the medical pre-clearance for your parents, book through a licensed operator, and get travel insurance with medical evacuation. Everything else — the peace, the dzongs, the mountain roads, the clean air — takes care of itself.
Frequently asked questions
Which airlines fly from Kolkata to Paro, Bhutan?
As of 2026, Druk Air (Royal Bhutan Airlines) and Bhutan Airlines are the only two carriers flying into Paro International Airport. Both serve Kolkata (CCU). Druk Air has more consistent schedules; Bhutan Airlines' Kolkata–Paro service should be confirmed directly on their website. No other carrier currently operates into Paro.
Is Bhutan safe for elderly parents with heart conditions?
Bhutan's main tourist circuit (Paro, Thimphu, Punakha) sits at 1,200–2,320 metres, which is moderate altitude. For elderly parents with well-controlled, stable heart conditions, it is often manageable with a slow itinerary and a pre-trip cardiology consultation. The cardiologist may adjust medications and will advise on warning signs. If there is active cardiac instability or severe heart failure, Bhutan is not advisable. Get written medical clearance before booking.
How scary is the Paro airport approach really?
Visually dramatic rather than genuinely dangerous. The aircraft makes steep turns through a mountain valley and you see peaks and tree lines very close outside the windows. Only specially certified pilots are authorised to land at Paro. The approach is safe but it is worth preparing nervous flyers (especially elderly parents) in advance so the turns and terrain views do not cause panic. Most passengers find it memorable and impressive rather than frightening once they know what to expect.
Can elderly parents do the Tiger's Nest hike at Paro?
The full Tiger's Nest hike (Paro Taktsang) involves about 900 metres of elevation gain over 4–5 hours — not suitable for most elderly travellers, especially those with joint or cardiac issues. However, horses are available for hire to carry you to a viewpoint at roughly the halfway point, from which you can see the monastery clearly. This is a popular option for elderly family members and gives an excellent view without the full ascent. Costs are typically in the range of USD 20–40 for the horse ride — confirm with your tour operator.
What altitude sickness medication should elderly parents take for Bhutan?
Acetazolamide (Diamox) is the most commonly prescribed altitude prophylaxis, but it requires a doctor's prescription and is contraindicated in sulfa allergies and several kidney and electrolyte conditions. Do not self-prescribe — have your parents' physician evaluate whether Diamox is appropriate for them given their complete medication list and medical history. Carry paracetamol for headaches, ORS sachets for hydration, and a pulse oximeter to monitor blood oxygen saturation during the trip.
Do Indian nationals need a visa for Bhutan?
Indian nationals do not need a visa for Bhutan — entry is permitted on a valid Indian passport or voter ID card. However, you still need to obtain a travel permit from the Department of Immigration on arrival (or through your tour operator), and as of recent rule updates, most visitors need to book through a licensed Bhutanese tour operator and pay the SDF (Sustainable Development Fee). Verify the current entry requirements and SDF rates for Indian nationals on the Tourism Council of Bhutan website (tourism.gov.bt) before planning.
