LoadingPlanning your Bhutan journey
The canonical answers to the questions every visitor asks before booking — when to come, how long to stay, the SDF, the visa, the Paro Airport approach, what to pack, what to eat, how to travel with children, what to carry in cash. Each guide is structured for the short-answer scan and the considered-read.

Bhutan rewards visitors year-round. The four seasons each carry a distinct register — Spring (March–May), Green Bhutan (June–August), Autumn (September–November), and Clear-Sky Bhutan (December–February) — and each window has its visitors who consider it the country at its best. The single window we actively discourage is **late July through early September**, when the heaviest Indian Monsoon rains arrive — sustained rainfall affects the roads, the cloud cover obscures the Himalayan panorama, and the high-altitude treks close. Our concierge checks the current monsoon forecast against every proposal's travel dates and adjusts the timing recommendation accordingly.
The Sustainable Development Fee (SDF) is a daily levy charged to every international visitor to Bhutan, paid in addition to lodge, guide, and transport costs. The current rate is USD 100 per person per night for most international visitors, confirmed through 31 August 2027. The SDF funds the Royal Government's free healthcare and free education programmes, forest conservation, and the broader carbon-negative national infrastructure.
All international visitors (with three exceptions — Indian, Bangladesh, and Maldives nationals) require a Bhutanese visa to enter the country. The visa is processed by the Royal Government-licensed tour operator handling your booking, granted on landing at Paro International Airport on the basis of the pre-issued e-visa clearance. The process takes approximately five working days from the operator's submission to the visa clearance.
Most international visitors spend between 5 and 10 nights in Bhutan. Five nights is the minimum for Bhutan (Paro, Thimphu, Punakha) at a considered pace. Seven nights adds Phobjikha or Bumthang. Ten nights opens the central valleys and the cultural depth most-considered visitors say they wish they had given themselves. Treks add 6 to 23 days on top of the cultural base. **The shapes below are our recommendations — not rules.** We design every itinerary against the visitor's specific preferences and constraints; if you want longer somewhere, or shorter, or a different sequence entirely, we adjust accordingly.
Paro International Airport (PBH) is Bhutan's only international airport, served by two carriers: Drukair (the national flag carrier) and Bhutan Airlines. **Paro is widely regarded as one of the most difficult airports in the world** — pilots fly a manual visual approach through a steep-walled valley between 5,000-metre peaks, and the airport's certification process means fewer than 50 pilots in the world are qualified to land there. The airport's safety record is strong; the difficulty refers to the technical demands of the approach, not to operational risk.
Bhutan's altitude range is substantial: 200 metres in the southern foothills, 2,200 metres in Paro (the airport), 2,300 metres in Thimphu, 3,000 metres in Phobjikha, 4,200 metres on the high trekking passes. For most visitors Bhutan is comfortably manageable with a 2-night Paro acclimatisation; high-altitude trekkers need a more profile. Our concierge tracks altitude exposure across every itinerary and adjusts pace where helpful.
