The Great Himalaya Trail (GHT) represents the most ambitious trekking route on Earth—a spectacular journey traversing the entire length of Nepal from east to west, offering not one but two distinct pathways through the world's highest mountain range. This monumental trail network stretches approximately 1,700 kilometers, connecting remote mountain communities, pristine wilderness areas, and all of Nepal's major trekking regions into a single epic adventure.
What makes the GHT truly unique is its dual-route system: the challenging high-altitude Upper Route and the more accessible Lower Route. These parallel paths offer dramatically different experiences of the Himalayas while sharing the same east-to-west trajectory across Nepal's northern landscapes.
The complete GHT showcases Nepal's extraordinary diversity—from subtropical forests to alpine meadows, from snow-capped 8,000-meter peaks to arid trans-Himalayan plateaus. Along the way, trekkers encounter Nepal's remarkable cultural heritage through dozens of distinct ethnic groups, each with their own languages, traditions, and spiritual practices that have evolved in these remote mountain environments over centuries.
Few adventurers complete the entire GHT in a single journey, with most choosing to experience sections over multiple visits to Nepal. Whether you're drawn to the extreme challenge of the high-altitude passes on the Upper Route or the cultural immersion and biodiversity of the Lower Route, the Great Himalaya Trail offers the ultimate Himalayan adventure for those seeking to experience Nepal beyond the standard trekking circuits.
