Nepal’s trekking history dates back to the early 1920s when two legendary mountaineers George Mallory and Andrew “Sandy” Irvine during British Everest Expedition of 1924 attempted to make their first human ascent to the world’s highest mountain, Everest. Unfortunately the duo vanished into thin air, leaving the entire globe a mystery of whether they made it to the top or not. They were last spotted by a teammate, Noel Odell, who saw them “going strong for the top” near the final stretch to the summit. Mallory’s body was found on Everest in 1999 but Irvine’s body was never found and the circumstances of their final moments remain uncertain. For centuries, the mountain trails of Nepal have been used by Himalayan traders, porters, migrating communities, and herders. Salt traders from Tibet would cross the high passes to reach the middle hills of Nepal and further on to lowlands of India for trading, swapping their wool and yak butter for rice, and other essentials. Years later those trails facilitated many travelers and mountaineers to embark on their adventure. Nepal was largely closed to the outside world until the 1950s. In 1951, after the fall of Rana dynasty there was a political change and this brought about a shift in Nepal’s foreign policy, leading the country opening its borders to the outside world. However in the year 1949, King Tribhuvan gave permission to Bill Tilman, the most notable name in the trekking industry of Nepal, to make several treks and exploration around Ganesh Himal, Kali Gandaki, Helambu, and Everest area. He was first trekker/ explorer in Nepal. But the organized trekking didn’t happen until 1965. The first organized trekking group in Nepal was led by colonel Jimmy Roberts in 1965 who accompanied Tilman on his first trek. Roberts is often referred to as the “Father of Trekking” in Nepal. He took a group of 3 elderly women to Everest Base Camp.
