Upper Mustang Forbidden Kingdom Trek

Trip Overview

The Upper Mustang Forbidden Kingdom Trek with Fly Trek Nepal takes you into the ancient Kingdom of Lo, a remote, high-desert region on the Tibetan border that stayed closed to foreigners until 1992. Beyond the village of Kagbeni, the landscape changes completely: green valleys give way to dry canyons, windswept ridges, and cliffs of red, ochre, and gold. Because Upper Mustang lies in the rain shadow of the Annapurna and Dhaulagiri ranges, it stays dry and sunny while much of Nepal gets monsoon rain.

The trail follows the Kali Gandaki valley north through whitewashed villages, cave dwellings, and ancient monasteries to Lo Manthang, the walled capital at about 3,840 m. Here, Tibetan Buddhist culture remains almost unchanged, with prayer flags, mani walls, chortens, and centuries-old gompas decorated with rare wall paintings. Upper Mustang is a restricted area, so you need a special permit and must trek with a licensed guide, which keeps the route quiet and authentic. Fly Trek Nepal arranges your permits, guide, and logistics, and you stay in comfortable teahouses, so you can focus on the scenery and the culture.
