The trek in Upper Mustang, Nepal is a once-in-a-lifetime chance to immerse yourself in the authentic mountain culture of the area, which is reminiscent of trekking in Tibet due to its proximity to the Tibetan border. This trek, known as the "forbidden kingdom trek," takes you to the capital of Lo-Manthang, where you can explore traditional architecture and visit the palace. You will also have the opportunity to hike to Chosar Cave or take a horseback riding tour. The trek takes place in a high-altitude desert region and offers views of the Annapurna, Nilgiri, and Dhaulagiri massifs. The trek is organized by Dilmaya Trek And Expedition Pvt. Ltd and may include the Tiji festival, a three-day ritual featuring performances by monks in elaborate costumes and masks.
