Every trekking company grades its routes, and no two use the same scale. A trek sold as moderate by one operator can be a 5,400 m pass crossing with a 10-hour day; sold as challenging by another, it can be a well-spaced walk to 4,100 m. That inconsistency makes the single most important planning decision — is this route right for me — harder than it should be.
This is what our five grades mean, and the four factors we weigh to set them.
The Four Factors Behind a Grade
- Daily effort — hours walking, metres of ascent and descent, and how many consecutive days without a rest.
- Maximum sleeping altitude — which drives both altitude risk and how cold and badly you sleep.
- Terrain and technical demand — stone staircases, moraine, snow, glacier, fixed rope, or a pass that needs crampons.
- Remoteness — how far you are from a road, a health post, and a helicopter landing site, and whether lodges exist at all.
Remoteness is the one most scales leave out, and it is why Makalu Base Camp is a harder proposition than Everest Base Camp despite being lower. On the Everest trail you are never more than a few hours from a lodge with a phone; in the Barun valley you can be two days from the nearest road.
The Five Grades
| Grade | Daily walking | Max altitude | Who it suits | Example routes |
|---|---|---|---|---|
| Easy | 3–5 hours, gentle gradients | Up to about 3,300 m | Anyone in reasonable health, families, first-timers | Poon Hill, Ama Yangri, Nagarkot, day tours and safaris |
| Moderate | 5–6 hours, sustained climbs and long descents | 3,500–4,500 m | Regular walkers with some hill experience | Mardi Himal, Annapurna Base Camp, Langtang Valley, Gokyo |
| Challenging | 6–8 hours, one or more 5,000 m passes or long remote stages | 4,500–5,500 m | Fit, experienced trekkers comfortable on consecutive long days | Manaslu Circuit, Tilicho Lake, Short Annapurna Circuit, Nar Phu |
| Difficult | 7–9 hours, high passes, snow, very remote | 5,000–5,800 m | Experienced high-altitude trekkers, ideally with pass experience | Everest Three Passes, Kanchenjunga, Upper Dolpo, Tilman Pass |
| Extreme | Long days on technical ground, glacier travel, camping | Above 5,500 m, or a climbing summit | Mountaineers and trekkers with technical skills | Sherpani Col, Tashi Lapcha, Saribung, peak climbs and expeditions |
Where Trekkers Misjudge the Grade
Four patterns come up repeatedly:
- Assuming altitude equals difficulty. Everest Base Camp reaches 5,545 m at Kala Patthar but is graded moderate, because the profile is gradual, the trail is good, and lodges and rescue are close. Khori Himal at 3,850 m is harder on the legs.
- Underestimating descent. The Annapurna stone staircases punish knees more than any climb on the route.
- Ignoring consecutive days. Seven days of six hours is much harder than two days of eight, and most people train for the wrong one.
- Treating a short trek as an easy one. The Short Annapurna Circuit compresses a 5,416 m pass into seven days, which makes it harder than the full circuit, not easier.
That last point is worth dwelling on when you compare a short itinerary with a long one. Fewer days at the same altitude means less acclimatisation, not less effort.
Choosing Your Grade Honestly
Work from what you have actually done rather than what you intend to do before departure.
| If your honest experience is… | Start with | Then progress to |
|---|---|---|
| Occasional day walks, no multi-day trekking | Easy — Poon Hill, Ama Yangri, Everest View | Moderate teahouse treks |
| Regular weekend hill walking | Moderate — Mardi Himal, Annapurna Base Camp, Langtang | Everest Base Camp, Gokyo, Tsum Valley |
| One or two high-altitude treks completed | Challenging — Manaslu Circuit, Annapurna Circuit, Tilicho | Three Passes, Kanchenjunga |
| Several 5,000 m treks, comfortable with cold camps | Difficult — Three Passes, Upper Dolpo, Rolwaling | Extreme passes and trekking peaks |
| Alpine climbing experience with rope and crampons | Trekking peaks — Yala, Island, Mera | Ama Dablam and 8,000 m expeditions |
Two practical notes on reading any itinerary. The daily hours quoted are walking time, not elapsed time — add an hour for tea stops, photographs and lunch, so a six-hour stage is a seven to eight hour day from lodge to lodge. And the metres of ascent matter more than the distance: a nine-kilometre day that climbs 1,100 m of stone steps between Chhomrong and Sinuwa is harder than a twenty-kilometre day on the Mustang road.
If a grade still feels ambiguous, the question to ask an operator is not how hard is it but what is the longest day and how much does it climb. Any route can be made harder by compressing it, and the day count is the clearest signal of how much margin an itinerary leaves you.
If you are between two grades, take the lower one and add a side trip. A trek you finish comfortably with energy to climb Kyanjin Ri or Gokyo Ri is a far better trip than one you survive. And tell us honestly at the enquiry stage what you have done — we would much rather move you to the right route before you book than watch an itinerary unravel at 4,900 m.
