To truly understand the importance of securing an Upper Mustang trekking permit, you must first appreciate the region’s unmatched cultural and geographical significance. Tucked away in the trans-Himalayan region of Nepal, Upper Mustang is one of the last places on earth where ancient Tibetan Buddhist traditions remain largely untouched. Known as the “Last Forbidden Kingdom,” this mystical land was closed to foreign visitors until 1992, preserving its centuries-old monasteries, sacred cave complexes, and barren, high-altitude desert landscapes.
Unlike the crowded trails of the Everest Base Camp, the Annapurna Circuit, and the Manaslu region trek, the Upper Mustang trek takes you deep into a living museum of Himalayan history. Here, colorful prayer flags flutter across wind-swept ridges, traditional stone-built villages echo with stories of the past, and the cultural richness is as breathtaking as the scenery. This is more than a trek — it's a spiritual and artistic pilgrimage into a hidden kingdom.
Due to its environmental sensitivity and cultural significance, the Nepalese government has designated Upper Mustang as a restricted area. As such, every foreign traveler must obtain a Restricted Area Permit (RAP), which can only be issued through a government-registered trekking agency. In addition to the RAP, trekkers also require an ACAP(Annapurna Conservation Area Project) permit. Depending on the route taken, a TIMS card may also be necessary. These permits not only allow you to trek legally but also help fund vital conservation and community development efforts across the Mustang region.
