Great Himalayan Trail — Complete Nepal Traverse (150 Days)

The Great Himalayan Trail , The Ultimate Mountain Journey on Earth

The Great Himalayan Trail is the longest and most challenging mountain trek in the world. A continuous traverse of Nepal’s entire Himalayan range from east to west , from Kanchenjunga on the Tibetan border to Humla on the far western frontier , covering approximately 1,700 kilometres, crossing 20+ passes above 5,000 metres, and accumulating over 150,000 metres of elevation gain and loss. Fewer than 125 people have ever completed it.

This is not a trek we recommend lightly. It demands exceptional fitness, mountaineering experience, mental resilience, and five to six months of your life. The reward is equally exceptional: the single greatest long-distance mountain journey on Earth, passing beneath eight of the world’s fourteen highest mountains and through the territories of 15 ethnic groups.

Two Routes , Upper (High) Route and Lower Route

The Great Himalayan Trail actually consists of two distinct routes through Nepal:

The High Route (Upper GHT)

This is the route we offer. It follows the highest possible line across the Nepal Himalaya , staying close to the glacial peaks, crossing technical passes, and traversing some of the most remote terrain on Earth. The High Route includes 2 passes exceeding 6,000 metres and 18 passes over 5,000 metres. It requires mountaineering skills for the glacier crossings and is graded Extreme (Grade 5).

Distance: ~1,700 km | Duration: 140–160 trekking days | Highest point: 6,190m (West Col) | Elevation gain/loss: 150,000m+

The Low Route (Lower GHT)

The Low Route follows Nepal’s mid-hills at lower altitudes, connecting traditional villages and cultural sites. It is longer in distance but technically easier , no mountaineering skills required. The Low Route is more culturally focused, passing through the heartlands of Nepal’s diverse ethnic communities. While we specialise in the High Route, we can design custom Low Route or combined itineraries on request.

Distance: ~1,500 km (mid-hills) | Duration: 100–120 days | Highest point: ~4,500m | Difficulty: Moderate to Challenging

The High Route , 7 Segments, 10 Sections

The High Route is typically divided into 7 operational segments with rest/transit days between them. Each segment covers 1–2 of the 10 geographic sections of Nepal’s Himalayan range.

Segment 1: Kanchenjunga to Makalu (Days 1–21)

Fly from Kathmandu to Taplejung via Bhadrapur. Trek through dense rhododendron forests into the Kanchenjunga Conservation Area.

What Makes This the Hardest Trek on Earth

• Duration: 150+ days of continuous trekking with no real rest. Far harder than climbing any single mountain.

• Technical passes: The Three Cols require full mountaineering skills , fixed ropes, glacier travel, crevasse rescue capability. Tashi Laptsa involves rockfall danger and glacier crossings.

• Cumulative elevation: Over 150,000 metres of total ascent and descent across five months. “Always either on a steep uphill to a pass or a steep downhill to a river.”

• Altitude: 2 passes above 6,000m, 18 passes above 5,000m. Constant altitude sickness risk across months.

• Remoteness: In Dolpo and Humla, you are days from any road, airstrip, or medical facility.

• Navigation: The GHT is not a single marked trail. It is a concept linking existing paths, passes, and routes. In western Nepal, trails disappear entirely.

• Resupply: In western Nepal, food and fuel must be carried for 20+ day stretches. No shops, no teahouses, no civilisation.

• Completion rate: Only approximately 125 people have ever completed the full High Route since its establishment.

Camping vs Teahouse

Approximately 60–70% of the High Route requires full expedition camping. Teahouse accommodation is available in the Khumbu/Everest section, parts of the Annapurna Circuit, parts of Langtang, and the Manaslu Circuit (basic). All expedition camping equipment is provided as part of our package.

Resupply Points

Major resupply points along the route (east to west):

• Taplejung , start, full supplies, airport
• Tumlingtar , airport, moderate supplies

History of the GHT

The Great Himalayan Trail was conceptualised by Robin Boustead, a British-New Zealand adventurer who spent five years researching the route before walking it over two seasons (162 days total). His guidebook “Nepal Trekking & the Great Himalaya Trail” remains the primary reference for the route.

Apa Sherpa , who summited Everest 21 times, more than anyone in history at that time , led the first complete GHT expedition in April 2012 alongside Dawa Steven Sherpa, completing the 1,555 km route in just 99 days.

The Fastest Known Time is held by South Africans Ryan Sandes and Ryno Griesel , 24 days, 3 hours, 24 minutes, set in March 2018. They were running, not trekking.

The trail crosses through the territory of 15+ ethnic groups including Sherpa, Tamang, Gurung, Thakali, Magar, Rai, Limbu, and Tibetan communities. The Dolpo section is where Peter Matthiessen wrote his classic “The Snow Leopard” (1978).

Permits Required

The GHT requires the most complex permit stack of any trek on Earth , 15+ separate permits across restricted areas and national parks:

Total permits: approximately ,000–3,500 per person. All permits are included in our package price.

Who This Trek Is For

• Previous high-altitude experience , at least two treks above 5,000m completed

• Mountaineering skills , crampon use, rope work, glacier travel. This is not the trek to learn on.

• Exceptional fitness , walking 6–8 hours daily for five months with a pack

• Mental resilience , weeks of isolation, basic camping, unpredictable weather

• 5–6 months of available time , this is an expedition, not a holiday

• Comprehensive insurance covering helicopter evacuation to 6,200m for the full duration

Can I Do the GHT in Sections?

Yes. Many trekkers complete the GHT in 2–4 separate expeditions over consecutive years. We can design section-based itineraries. The most popular standalone sections are:

• Kanchenjunga section (18–20 days)
• The Three Cols , Makalu to Everest (12–15 days) , the most technically demanding
• Dolpo (20–25 days) , the most remote and culturally unique
• Manaslu + Annapurna combined (30–35 days)
