What Affects the Answer
Cultural depth is the biggest factor. Upper Mustang was a separate Buddhist kingdom until 2008 and the walled capital of Lo Manthang retains the 15th century royal palace, 4 active monasteries, and the annual Tiji festival in May. Scenic uniqueness is the second factor. The rain shadow landscape of red and orange cliffs and barren valleys has no equivalent in the Himalaya. Crowd level is the third factor. Upper Mustang sees 3,000 annual trekkers versus 130,000 on Annapurna Base Camp.
Season is the fourth factor. June to September is the best time because the rain shadow keeps Mustang dry while the rest of Nepal is in monsoon. Permit cost is the fifth factor. The USD 500 restricted area permit for 10 days is the most expensive in Nepal.
Booking Tips
Book through a Kathmandu agency 8 to 12 weeks ahead because the Upper Mustang Restricted Area Permit requires 14 days of processing and a minimum group of 2 trekkers plus a licensed guide. Carry USD 400 to USD 600 in cash because no ATMs operate beyond Jomsom. Time the trek for the May Tiji festival in Lo Manthang. Pack a 0 C sleeping bag for June nights at 3,840 m, a windproof jacket for the Kali Gandaki wind, and a sun hat for the high UV.
Comparison With Alternatives
The Upper Dolpo Trek runs 18 to 24 days to 5,360 m with 400 annual trekkers and costs USD 3,000 to USD 4,500. The Nar Phu Valley Trek runs 12 to 16 days to 5,320 m with 300 annual trekkers and costs USD 1,500 to USD 2,200. The Tsum Valley Trek runs 14 to 18 days to 3,700 m with 1,200 annual trekkers and costs USD 1,200 to USD 1,800. Upper Mustang is the most culturally intact.
Common Mistakes to Avoid
A common mistake is to attempt Upper Mustang in winter. December to February sees 1 to 2 m of snow at the 4,000 m passes and the Jomsom flight cancels 60 to 80 percent of the time. A second mistake is to rush the Lo Manthang stay. The walled capital needs 3 nights to visit the 4 monasteries and the Chhoser caves. A third mistake is to skip the eastern return via Ghar Gompa. The 8th century monastery is the oldest in Upper Mustang.
