Upper Mustang Trek in Monsoon: A Rain Shadow Escape

When most people think of trekking in Nepal during the monsoon, they picture muddy trails, leech-infested forests, and heavy rain clouds blotting out the mountain views. But there’s a secret escape in the Himalayas—Upper Mustang—a region untouched by the monsoon's fury due to its unique rain shadow location.

Tucked behind the towering Annapurna and Dhaulagiri massifs, Upper Mustang offers a dry and mystical trekking experience even in peak monsoon months (June to September). 

Why Trek Upper Mustang During Monsoon?

Rain Shadow Geography

Upper Mustang lies north of the main Himalayan range, in a region that receives minimal rainfall due to the natural barrier created by the mountains. While most of Nepal is drenched, Mustang stays arid and trekker-friendly.

Fewer Crowds

Unlike the bustling trails of Everest and Annapurna during peak seasons, Upper Mustang remains peaceful in monsoon. You’ll often have entire trails and teahouses to yourself—perfect for cultural immersion and mindfulness.

Clear Skies & Striking Colors

Oddly enough, monsoon can offer the clearest skies here. The rain washes away the dust, enhancing the earthy red cliffs, ochre canyons, and dramatic rock formations. It’s a photographer’s paradise.

What Makes Upper Mustang Special?

Kingdom of Lo

Until 1992, Upper Mustang was a restricted demilitarized zone, and even today, it retains a strong sense of cultural and political isolation. The walled city of Lo Manthang, once the capital of the Mustang Kingdom, still stands with whitewashed homes, royal palaces, and labyrinthine alleys.

Tibetan Buddhism & Sky Caves

Upper Mustang is home to deeply spiritual Tibetan Buddhist communities. Centuries-old monasteries like Thubchen and Jampa Lhakhang, as well as mysterious sky caves carved high into cliffs—believed to be meditation chambers and burial sites—add to its sacred aura.

Local Culture and Language

The people of Upper Mustang, known as Lobas, share a close cultural affinity with Tibetans. They speak a dialect called Loke (a Tibetan offshoot), wear traditional woolen garments, and follow agrarian and trade-based livelihoods. Hospitality is deeply rooted in their way of life.

Cultural Experiences in Monsoon

Tiji Festival (Usually in May or June)

If your timing aligns, witness the Tiji Festival in Lo Manthang—a vibrant, three-day Buddhist celebration that reenacts the victory of good over evil through masked dances and chants. Even during early monsoon, this spiritual event draws monks, pilgrims, and few lucky travelers.

Authentic Cuisine

Taste Tsampa (roasted barley flour), Thukpa (noodle soup), and Yak butter tea—simple yet nourishing local foods. The monsoon harvests bring fresh barley, wild herbs, and fruits to the region.

Accommodation and Amenities

Despite its remoteness, Upper Mustang offers comfortable teahouses and eco-lodges. Many are run by local families, ensuring warm hospitality. Solar-heated showers and Wi-Fi (in limited areas) are increasingly common.

Permits & Essentials

Upper Mustang is a restricted area and requires:

• Restricted Area Permit (RAP): USD 500 for the first 10 days, USD 50 per extra day

• Annapurna Conservation Area Permit (ACAP): NPR 3,000

These can be arranged easily through registered trekking agencies like Places Nepal Treks, ensuring smooth logistics and expert local guidance.
