Everything you need to know before trekking in Bhutan — visas, seasons, fitness, equipment, and altitude safety.
Bhutan's trekking seasons are defined by the Himalayan monsoon and winter snowfall. Two primary windows offer ideal conditions:
Rhododendrons in full bloom, clear pre-monsoon skies, and warming temperatures. Excellent for lower and mid-altitude treks. Some snowfields on high passes.
The peak trekking season. Post-monsoon clarity delivers the best mountain visibility of the year. Stable weather, crisp temperatures. Busiest period — book early.
Heavy rainfall from the Bay of Bengal brings high humidity, flooded trails, and leeches. High passes may be impassable. Not recommended for trekking.
High passes are blocked by snow above 4,000m. Lower valley treks (Druk Path, Chele La) may be possible in good weather periods, but temperatures are extreme.
Paro International Airport is Bhutan's only international airport. Drukair and Bhutan Airlines serve the following routes:
Alternatively, overland entry is possible via Phuntsholing (4 hours from Bagdogra airport, West Bengal) or Samdrup Jongkhar (3 hours from Guwahati).
All visitors except Indian, Bangladeshi, and Maldivian nationals require a visa to enter Bhutan. The visa process works as follows:
✅ Note: Trek Bhutan handles all visa arrangements as part of your trip booking. You do not need to apply independently.
Bhutan operates a "High Value, Low Volume" tourism policy. All visitors are charged a Sustainable Development Fee (SDF) which funds Bhutan's public services, carbon-neutral policy, and conservation programmes. The fee is set by the Tourism Council of Bhutan and is included in all trek packages. Contact us for current fee information as this can change annually.
Trekking in Bhutan is fundamentally different from Nepal or other destinations. There are no teahouses on the trail — all treks are fully-supported camping expeditions. This means:
🏕 You carry only your daypack — typically 3–5kg including water, a camera, snacks, and a warm layer. All heavy gear travels with the horses.
Every trek is staffed by a dedicated team. For a group of 2 trekkers, expect:
Larger groups scale proportionally. For 12 trekkers, expect 11 support staff and approximately 40 horses.
Camp meals are a highlight of trekking in Bhutan — surprisingly comprehensive given the remote setting:
Water: Assistants collect and boil water from rivers and streams daily. All drinking water is safe. Bring water purification tablets as backup.
Our guides receive annual certification training covering:
All guides carry emergency communication equipment and first aid kits on every trek.
Trek camps are set up at designated National Park campsites. What to expect:
You should bring your own sleeping bag rated to at least -8°C to -10°C. See the equipment list for details.
Trekking in Bhutan is demanding. Most trails involve vigorous ascents and descents with elevation gains of 300 to 900 metres per day, across distances of 8 to 22 kilometres. Terrain ranges from rocky moraine and muddy trails to snow at high passes.
Minimum recommended fitness level per trek:
Druk Path, Chele La, Soi Yaksa:
Jumolhari, Laya Gasa:
Essential requirements for the Snowman Trek:
⚠️ Medical clearance: We strongly recommend a pre-trip medical consultation for any trek above 4,000m. Those with heart conditions, severe asthma, or known susceptibility to altitude sickness should discuss the risks with their doctor. We can provide a medical questionnaire on request.
Comprehensive travel and medical insurance is mandatory for all Trek Bhutan expeditions. Your policy must include:
Please bring your insurance details and emergency contact numbers. Share them with our team before the trek begins.

Acute Mountain Sickness (AMS) is caused by reduced oxygen availability at altitude and is a serious consideration on all Bhutan treks. It can affect anyone, regardless of fitness level. Understanding the symptoms and appropriate responses is essential.
Most Bhutan treks spend multiple nights above 3,500m, and several passes exceed 5,000m. Proper acclimatisation and vigilance are non-negotiable.
Mild AMS — common above 2,500m:
Severe AMS — descend immediately if experienced:
⚠️ Golden rule: Never ascend with AMS symptoms. Any trekker showing severe symptoms must descend to a lower altitude immediately, regardless of time of day or weather conditions.

Treatment:
✅ Our guides are trained and certified in altitude sickness prevention, recognition, and treatment. They carry emergency medication and can arrange helicopter evacuation if required.
In the event of a medical emergency requiring evacuation from the trail, our guides carry satellite communication equipment and can coordinate helicopter rescue. Helicopter evacuation from Bhutan's high-altitude areas is expensive — this is why comprehensive travel insurance including helicopter evacuation is mandatory for all trek participants.
