Nepal is home to network of trails also called the Great Himalaya Trails, an extensive trail system that covers Nepal from Humla and Darchula in the west to Kanchenjunga in the east. The diversity of trekking in Nepal cannot be found in any other region of the world. In fact, the lowest point in Nepal is 59 m above sea-level in the Terai region while the highest point is Everest, 8,848 m above sea-level, the two points are, in a straight line, only 200 kilometres apart.

The majority of visitors to Nepal come in via the Tribuvan International Airport in Kathmandu. It is in Kathmandu that trekkers need to acquire their permits and other documentation, either from a trekking agent or from the appropriate offices. These documents will be checked along the trekking route. For those with little time to spend in Nepal there are half-day hikes from Kathmandu to witness breathtaking Himalayan views otherwise trek for weeks over stunning challenging mountain passes.
