Practical Information

Everything you need to know before trekking in Bhutan — visas, seasons, fitness, equipment, and altitude safety.

🗓 Best Trekking Seasons

Bhutan's trekking seasons are defined by the Himalayan monsoon and winter snowfall. Two primary windows offer ideal conditions:

🌸 Spring — March to May

Rhododendrons in full bloom, clear pre-monsoon skies, and warming temperatures. Excellent for lower and mid-altitude treks. Some snowfields on high passes.

🍂 Autumn — September to November

The peak trekking season. Post-monsoon clarity delivers the best mountain visibility of the year. Stable weather, crisp temperatures. Busiest period — book early.

🌧 Monsoon — June to August

Heavy rainfall from the Bay of Bengal brings high humidity, flooded trails, and leeches. High passes may be impassable. Not recommended for trekking.

❄️ Winter — December to February

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.

✈️ Getting to Bhutan

Paro International Airport is Bhutan's only international airport. Drukair and Bhutan Airlines serve the following routes:

  • Bangkok (BKK) — most popular connection hub
  • Delhi (DEL) and Kolkata (CCU), India
  • Kathmandu (KTM), Nepal
  • Guwahati (GAU), India
  • Singapore (SIN) — seasonal

Alternatively, overland entry is possible via Phuntsholing (4 hours from Bagdogra airport, West Bengal) or Samdrup Jongkhar (3 hours from Guwahati).

🛂 Bhutan Visa Requirements

All visitors except Indian, Bangladeshi, and Maldivian nationals require a visa to enter Bhutan. The visa process works as follows:

  • Visa Approval Letter is arranged by your tour operator (us) through the Tourism Council of Bhutan
  • Bring a copy of the Approval Letter to check-in — required by airlines
  • Actual visa stamp is issued on arrival at Paro airport
  • Your passport must be valid for at least 6 months beyond travel dates
  • A blank passport page is required for the visa stamp
  • Travel must be with the same passport used during application

Note: Trek Bhutan handles all visa arrangements as part of your trip booking. You do not need to apply independently.

💰 Bhutan Sustainable Development Fee

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.

How Trekking Works in Bhutan

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:

  • Our team pitches your tent camp at each campsite before you arrive
  • Hot tea and snacks await you in the dining tent after the day's walk
  • A full kitchen operates in camp — serving three proper meals daily
  • Toilet tents are erected at each campsite
  • All cooking equipment, dining furniture, and camping gear is transported by horses

🏕 You carry only your daypack — typically 3–5kg including water, a camera, snacks, and a warm layer. All heavy gear travels with the horses.

👥 Support Team

Every trek is staffed by a dedicated team. For a group of 2 trekkers, expect:

  • 1 certified lead guide
  • 1 assistant guide
  • 1 trek chef
  • 1 kitchen assistant
  • 2–3 horsemen with 6–8 horses

Larger groups scale proportionally. For 12 trekkers, expect 11 support staff and approximately 40 horses.

🍽 Food & Water

Camp meals are a highlight of trekking in Bhutan — surprisingly comprehensive given the remote setting:

  • Breakfast: Porridge, eggs, toast, fruit, tea/coffee
  • Packed Lunch: Sandwiches, boiled eggs, fruit, crackers on trail
  • Dinner: Multi-course — soup, rice/pasta, vegetables, meat or dal, dessert

Water: Assistants collect and boil water from rivers and streams daily. All drinking water is safe. Bring water purification tablets as backup.

🧭 Guides & Route Safety

Our guides receive annual certification training covering:

  • Wilderness first aid and emergency response
  • Altitude sickness prevention, recognition, and treatment
  • Navigation and trail hazard identification (slippery slopes, loose rocks, river crossings)
  • Bhutanese cultural and natural history interpretation

All guides carry emergency communication equipment and first aid kits on every trek.

🏕 Camping Conditions

Trek camps are set up at designated National Park campsites. What to expect:

  • 2-person dome tents with foam sleeping mats
  • Separate dining tent with table and chairs
  • Kitchen tent with gas cookers
  • Basic toilet tent (trowel-and-bury system)
  • Washing basin with hot water in morning

You should bring your own sleeping bag rated to at least -8°C to -10°C. See the equipment list for details.

💪 Physical Fitness Requirements

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:

Short Treks (3–6 days)

Druk Path, Chele La, Soi Yaksa:

  • Regular walking or hiking experience
  • Able to walk 10–15 km on hilly terrain
  • No prior high-altitude experience required
  • Good general fitness — begin training 4–8 weeks before

Major Treks (12–13 days)

Jumolhari, Laya Gasa:

  • Prior multi-day trekking experience essential
  • Comfortable walking 15–20 km on mountain terrain
  • Able to ascend 800–900m in a single day
  • Experience above 3,500m recommended
  • Training: 3–6 months of regular hiking with loaded daypack

Snowman Trek (28 days)

Essential requirements for the Snowman Trek:

  • Extensive multi-day high-altitude trekking experience (minimum 1 prior trek above 4,500m)
  • Comfortable trekking 18–22 km per day for weeks at a time
  • Good acclimatisation history — no significant AMS episodes in the past
  • Strong core and leg fitness: squats, lunges, stair climbs with pack
  • Training programme: 6–12 months of dedicated preparation recommended

⚠️ 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.

🏥 Medical Preparation

  • Consult your doctor 6–8 weeks before departure
  • Ensure standard vaccinations are up to date (Hep A, Typhoid, Tetanus)
  • Discuss Acetazolamide (Diamox) prescription for altitude prevention
  • Carry a personal first-aid kit — see equipment tab
  • Dental check before long expeditions
  • Eye test if you use contact lenses (dust & altitude can cause issues)

🛡 Travel Insurance

Comprehensive travel and medical insurance is mandatory for all Trek Bhutan expeditions. Your policy must include:

  • Emergency medical evacuation (helicopter rescue)
  • High-altitude trekking coverage (above 4,000m)
  • Trip cancellation and interruption
  • Medical treatment costs

Please bring your insurance details and emergency contact numbers. Share them with our team before the trek begins.

🏔 Understanding Altitude Sickness (AMS)

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.

⚠️ AMS Symptoms

Mild AMS — common above 2,500m:

  • Headache (most common symptom)
  • Fatigue and weakness
  • Nausea or mild vomiting
  • Dizziness or light-headedness
  • Difficulty sleeping

Severe AMS — descend immediately if experienced:

  • Severe, persistent headache not relieved by painkillers
  • Ataxia (inability to walk straight)
  • Breathlessness at rest
  • Confusion or altered mental state
  • Wet cough or gurgling breath sounds (HAPE)

⚠️ 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.

Prevention & Treatment

Prevention:

  • Ascend gradually — our itineraries are designed with acclimatisation days built in
  • Drink 3–4 litres of water daily on trek
  • Avoid alcohol, sleeping pills, and sedatives at altitude
  • Eat lightly — avoid heavy, fatty meals in the first days at altitude
  • Discuss Acetazolamide (Diamox) with your doctor before the trek

Treatment:

  • Rest at current altitude — do not ascend further until symptoms resolve
  • Take paracetamol for headache
  • Hydrate well — warm fluids preferred
  • If symptoms persist or worsen: descend immediately
  • Inform your guide — they are trained in AMS management

Our guides are trained and certified in altitude sickness prevention, recognition, and treatment. They carry emergency medication and can arrange helicopter evacuation if required.

🚁 Emergency Evacuation

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.

Before your trek begins, please provide your guide with:

  • Your insurance company name and policy number
  • The 24-hour emergency assistance phone number
  • A next-of-kin contact
  • Any relevant medical history your guide should be aware of
