Great Himalaya Trail

The Great Himalaya Trail is a continent-spanning concept realised most fully in Nepal, where a high route threads roughly 1,700 kilometres from Kanchenjunga in the far east to Humla and Darchula in the west. It stitches together the country's classic trekking regions into one continuous traverse just below the giants of the range.

Its appeal is completeness: rather than a single valley, it links Kanchenjunga, Makalu, Everest, Rolwaling, Langtang, Manaslu, Annapurna, Dolpo and Humla, passing through Sherpa, Rai, Tamang, Gurung and Tibetan-influenced cultures in a single arc across the roof of the world.

As an undertaking the full high route takes around 150 days and crosses numerous passes above 5,000 metres, several near 6,000, with glacier travel, remote camps and long stretches without resupply. It is expedition-grade, demanding strong acclimatisation, self-sufficiency and experienced guides; most people walk it in themed sections over several seasons rather than in one push.

Practical notes: many segments cross restricted zones requiring special permits, a licensed guide and a registered agency, on top of standard conservation-area fees. Spring and autumn are the working seasons; winter shuts the high passes and monsoon floods the lower approaches. A lower cultural variant follows villages at gentler altitude for those not chasing the full alpine line.
