Locked away in the wilderness of the Himalayas, on the very edge of the Tibetan plateau, lies the secret, ancient kingdom of Mustang, known to its inhabitants as the land of Lo. After decades of isolation, Mustang has only really opened its borders in the last 25 years or so. This is a spectacular land whose history and culture are steeped in ancient customs and traditions. There are few places left in the world where time is measured not in minutes but according to the rate at which crops grow in the spring and fruits ripen in the autumn. The planned walks pass through open valleys, deep ravines, desert canyons, grasslands with white-walled villages and ancient cave homes all set against the magnificent backdrop of the soaring snow-capped Himalayan peaks.
