Bhutan is one of the finest trekking destinations in the world, and one of the least crowded. The routes pass through terrain that genuinely earns that description — high alpine passes, ancient monasteries accessible only on foot, pristine temperate forests, and Himalayan panoramas of a scale that is difficult to describe without sounding hyperbolic.
What makes trekking in Bhutan different from Nepal or northern India is the same thing that makes Bhutan different from everywhere else: the controlled approach to tourism means that even the most popular trekking routes feel quiet. You are rarely sharing a trail with large groups. The landscape feels intact because it is.
This guide covers every major trekking route in Bhutan — what each offers, how difficult it is, what permits you need, and which season suits it best. It is written by our team in Thimphu, who have guided these routes in every season.
How Trekking Works in Bhutan
You Must Trek With a Licensed Guide
All trekking in Bhutan requires a licensed guide. This is not optional — it is a condition of your trek permit. Your guide is arranged by your licensed operator and accompanies you for the full duration of the trek.
This requirement, which some trekkers initially view as a constraint, almost universally becomes one of the valued elements of a Bhutan trekking experience. A knowledgeable Bhutanese guide brings the landscape, history, and culture alive in ways that a solo trekker following a map simply cannot access.
Permits for Trekking
All trekking routes in Bhutan require permits beyond the standard visitor visa. These include:
- Trekking permit — required for all routes, processed by your operator
- National Park permit — required for routes passing through protected areas such as Jigme Dorji National Park (Jhomolhari and Laya routes)
- Restricted Area Permit — required for certain zones, including Merak-Sakteng in eastern Bhutan
Your operator arranges all permits as part of your trek package. You do not apply for them separately. Confirm with your operator which permits are included in your quoted package.
What Is Included in a Trek Package
A standard Bhutan trek package includes:
- Licensed trekking guide
- Cook and kitchen crew
- Pack animals (horses or yaks depending on the route and altitude)
- Full camping equipment — tents, sleeping mats, kitchen and dining tents
- All meals on the trail (typically three meals per day)
- Emergency communication equipment
What you bring personally: your sleeping bag, trekking clothing and layers, boots, trekking poles if desired, and personal items. Your operator will provide a full kit list when you confirm a trek.
The Major Trekking Routes
Druk Path Trek — 5 to 6 Days
Difficulty: Moderate Maximum altitude: 4,210m (Labana Pass) Best season: March–May, October–November Start/End: Paro to Thimphu
The Druk Path is Bhutan’s most popular trekking route and an excellent introduction to high-altitude trekking in the Himalayas. It connects Paro and Thimphu through a series of high ridges and alpine lakes, passing ancient Dzongs and remote meditation retreats along the way.
The trail offers consistent mountain views — on clear days, the north face reveals a long panorama of Himalayan peaks. The five lakes on the high plateau (Jimilang Tsho, Janetso, Ludrong, Tshokam, and Simkota) are among the most beautiful high-altitude lakes in the country.
The Druk Path is accessible to fit travelers with some previous hiking experience. You do not need technical mountaineering skills, but you should be comfortable walking five to seven hours per day at altitude and sleeping in tents at temperatures that drop well below zero overnight in the shoulder seasons.
Jhomolhari Trek — 8 to 12 Days
Difficulty: Moderate to Challenging Maximum altitude: 4,930m (Jhomolhari base, Bhonte La pass) Best season: April–May, September–November Start/End: Paro (both ends, or Thimphu finish)
The Jhomolhari Trek is one of the great Himalayan treks. It takes you deep into Jigme Dorji National Park — Bhutan’s largest protected area — to the base of Jhomolhari (7,326m), one of the most sacred peaks in Bhutan. The route passes through yak pastures, ancient fortresses, and valleys that are entirely road-less and accessible only on foot.
The most dramatic moment comes at Camp 1, at 4,080 meters, where Jhomolhari rises almost vertically above the valley floor. The mountain is not climbed — it is considered sacred and climbing is prohibited — but the approach to its base is one of the most powerful experiences available on foot anywhere in the Himalayas.
The longer version of the route crosses the Nyile La and Tshele La passes, adding significant altitude and extending the journey to twelve days. Both versions are exceptional. The shorter version suits trekkers who are fit but cautious about altitude; the longer version is for experienced trekkers comfortable at sustained high altitude.

Dagala Thousand Lakes Trek — 5 to 6 Days
Difficulty: Moderate Maximum altitude: 4,520m Best season: April–May, September–October Start/End: Thimphu
A less well-known route that rewards trekkers looking for solitude. The Dagala range south of Thimphu is dotted with dozens of high alpine lakes, and the route climbs through dense temperate forest before breaking out onto open ridgelines with views across the Bhutanese Himalaya.
Wildlife is a feature of this trek — the forests are home to takins (Bhutan’s national animal), blue sheep, and a variety of Himalayan bird species. Snow leopard territory begins at the upper elevations, though sightings are rare.
A good alternative to the Druk Path for travellers who want a comparable experience with fewer other trekkers on the trail.

Bumthang Cultural Trek — 3 Days
Difficulty: Easy to Moderate Maximum altitude: 3,500m Best season: March–May, September–November Start/End: Bumthang valley
The Bumthang Cultural Trek is less about altitude and more about immersion. It crosses the Tang and Chhokhor valleys of Bumthang — the spiritual heartland of Bhutan — passing ancient temples, farmhouses, and monasteries that would be difficult or impossible to visit by vehicle.
This is the right trek for travelers who are more interested in cultural depth than high-altitude challenge. Nights are spent in farmhouses rather than tents, making it a genuinely local experience. The maximum altitude is manageable even for less experienced trekkers.

Snowman Trek — 25 to 30 Days
Difficulty: Very Challenging Maximum altitude: 5,320m (Rinchenzoe Pass) Best season: September–October only Start/End: Paro to Bumthang (or reverse)
The Snowman Trek is widely regarded as one of the most difficult trekking routes in the world. It crosses eleven passes above 4,500 metres, traverses some of the most remote terrain in the Himalayas, and demands a minimum of 25 days on the trail. Weather windows are narrow — September and October are the only viable months, and even then, unexpected snowfall can close passes.
Completion rates are low. The route demands exceptional fitness, strong altitude acclimatisation, and psychological resilience for extended periods of remoteness. Logistically, it requires an experienced operator, a full support crew, and thorough preparation.
For the right trekker — experienced, well-prepared, and with the time to commit — the Snowman Trek is an extraordinary undertaking. We arrange a small number of Snowman expeditions each year and give each one the detailed planning it requires.
Enquire well in advance if this is on your list.

When to Trek in Bhutan
Spring (March–May) — Excellent
Trails are clear from snow below 4,000m by April. Rhododendrons in full bloom along lower and mid-elevation trails. Mountain visibility is good. April and May are the peak trekking months alongside October.
Autumn (September–November) — Best Overall
Post-monsoon skies are the clearest of the year. Trail conditions are excellent from late September onward. Mountain views are sharpest in October. The single best month for high-altitude trekking is October.
Winter (December–February) — Limited
Most high-altitude passes are closed by snow. Lower-elevation routes such as the Bumthang Cultural Trek remain accessible. Not recommended for Jhomolhari or Druk Path.
Monsoon (June–August) — Not Advised
Trails are wet, leeches are active at lower elevations, and mountain views are obscured. Trekking in Bhutan during the monsoon is not recommended.
Fitness and Preparation
What Level of Fitness Is Required?
For the Druk Path and Dagala treks, you should be able to walk five to seven hours per day comfortably on uneven terrain. Regular hiking experience is beneficial. No technical climbing skills are required.
For the Jhomolhari trek, a higher baseline fitness is expected — sustained altitude above 4,000 metres for multiple consecutive days requires cardio respiratory capacity that benefits from specific preparation.
Acclimatisation
Arriving in Bhutan and trekking immediately is not advisable. We recommend at least one to two nights in Paro or Thimphu before beginning any high-altitude route. For the Jhomolhari trek, a minimum of two acclimatisation days in the valleys before ascending is built into most itineraries.
What to Pack
Essential items for any Bhutan trek:
- Broken-in, waterproof trekking boots
- Sleeping bag rated to -10°C (can be rented in Paro or Thimphu or Ambo tours will provide it)
- Trekking poles
- Moisture-wicking base layers and insulating mid-layers
- Waterproof outer shell — jacket and trousers
- Sun protection — high-SPF sunscreen, lip balm, sunglasses, hat
- Personal first aid kit including altitude medication (discuss with your doctor before travel)
- Headtorch with spare batteries
- Trekking gaiters for shoulder season snow
We will provide a detailed equipment list specific to your chosen route.
Altitude Sickness — What to Know
Acute Mountain Sickness (AMS) can affect any trekker at altitude, regardless of fitness. Symptoms include headache, nausea, dizziness, and fatigue. Most cases are mild and resolve with rest and acclimatisation. Severe AMS requires immediate descent.
The standard medication for altitude prevention — Acetazolamide (Diamox) — is available on prescription in most countries and should be discussed with your doctor before your trip. Your guide is trained to recognise symptoms and will advise on pace and rest days.
Frequently Asked Questions
Do I need prior trekking experience to trek in Bhutan?
For the Bumthang Cultural Trek and Druk Path, regular hiking experience is sufficient. Previous multi-day trekking experience in mountain terrain is strongly recommended for Jhomolhari. The Snowman Trek requires significant expedition experience.
Can I combine trekking with a cultural itinerary?
Yes, and this is one of the most satisfying structures for a Bhutan trip. A typical 10-day itinerary might spend four to five days on the Druk Path and the remainder visiting Paro, Thimphu, and Punakha. We design combined itineraries regularly.
Is altitude sickness a serious concern on Bhutan treks?
It is a consideration on all routes above 3,500 metres, particularly the Jhomolhari and Dagala treks. Good acclimatisation, a sensible pace, and awareness of symptoms manage the risk effectively. Most trekkers complete their chosen routes without significant altitude issues.
What happens if weather prevents us from completing a pass?
Your guide and operator make the final call on safety and route viability. If a pass is closed by weather or snow, your guide will advise on alternatives — there are usually options depending on which point of the route is affected. We build flexibility into trekking itineraries for exactly this reason.
