Tucked away behind the towering 8,000-meter peaks of Annapurna and Dhaulagiri lies a mystical and rarely explored region: the Forbidden Kingdom of Mustang. Once an independent kingdom known as Lo, Mustang remained isolated from the outside world for centuries, opening its borders to foreigners only in 1992. What awaits those fortunate enough to venture here is a starkly beautiful and spiritually rich landscape shaped by time, isolation, and Tibetan Buddhist heritage.

Mustang: A Land Lost in Time

Nestled along the upper Kali Gandaki River — the deepest river gorge in the world — Mustang is a remote region defined by arid high deserts, wild rock formations, snow-clad peaks, ancient monasteries, and cave hermitages carved into crumbling cliffs. People have lived in this seemingly inhospitable terrain for thousands of years. Early settlers meditated in cave dwellings filled with Buddhist art, while later generations established fortified villages that seem frozen in medieval time.

Historically, Mustang played a key role in trans-Himalayan trade between Nepal and Tibet. The Kingdom of Lo, founded in the 15th century, ruled not only Mustang but also other distant Himalayan regions like Dolpo. Mustang eventually became part of Nepal in 1951. During the Cold War era, Khampa fighters resisting the Chinese occupation of Tibet used Mustang as a base, which led to the area being off-limits to outsiders until the early 1990s. Even today, access requires a special restricted area permit, helping to conserve its culture and fragile environment.

Trekking Through the Mythical Land

The classic Upper Mustang trek allows adventurers to journey into the heart of this hidden world. The trek typically includes:

• Visits to Lo Manthang, the walled capital of Mustang
• Remote valleys along ancient salt trade routes
• Traditional villages like Dhi, Yara, and Tetang
• The sacred pilgrimage site of Muktinath

Trekkers traverse wind-blown plateaus, red-and-ochre cliffs, and hidden gompas that echo with the chants of monks. A 10-day special permit allows for deep exploration into this magical landscape where Tibetan Buddhism thrives untouched by time.

Tilicho Lake: Trekking to the World’s Highest Lake

For those seeking an added challenge and unspoiled beauty, Tilicho Lake — perched at 5,200 meters — offers a stunning extension to the Mustang experience. Fed by glaciers from Annapurna and Thorong Peak, this turquoise lake is considered one of the highest in the world.

The trek to Tilicho branches off from the Annapurna Circuit after reaching Muktinath, following a more remote and rugged route. Unlike the well-trodden Thorong La, the path to Tilicho demands camping gear and full self-sufficiency. Beyond Tilicho Base Camp, there are no teahouses or villages until you descend into Thini Gaon or Jomsom.

Two high passes — Mesokanto La and Tilicho North Pass (also called the Tourist Pass) — lead trekkers across glaciated trails with sweeping views of the Himalayas. These passes are often snow-covered, even in the dry season, and demand proper gear, guides, and preparation for snowstorms or sub-zero nights.

Why Combine Mustang with Tilicho Lake?

• Wild & Sacred: Both regions offer not only breathtaking natural beauty but spiritual depth through monasteries, pilgrimage sites, and local traditions.
• Offbeat Adventure: You’ll avoid the crowds of the classic Annapurna Circuit, venturing into pristine wilderness.
• Cultural Immersion: Experience Tibetan-Nepali communities living much as they have for centuries.
• Challenging Trekking: Ideal for seasoned trekkers looking for an alternative to the traditional passes.

Travel Tips

• Best Time to Trek: April to mid-November is ideal. Mustang lies in the rain-shadow, making it trek-friendly even during the monsoon.
• Permits Required: Restricted Area Permit for Mustang, ACAP (Annapurna Conservation Area Permit), and TIMS.
• Experience Needed: Moderate to advanced trekking experience recommended, especially for Tilicho.

Trekking through Mustang and Tilicho Lake is a journey into a forgotten kingdom, where timeless traditions, Himalayan grandeur, and spiritual solitude converge. This is not just a trek — it’s an expedition into the heart of one of the world’s last great wildernesses. Whether you’re drawn by the legend of the Forbidden Kingdom or the allure of Tilicho’s glacial beauty, this adventure will forever change how you see the Himalayas.
