Exploring Upper Mustang: The Last Forbidden Kingdom of Nepal

Exploring the Forbidden Kingdom of Nepal should undoubtedly be on your bucket list if you enjoy the untainted beauty of unspoiled landscapes and the excitement of seeing locations with rich cultural traditions.

Nestled in the rain-shadow of the Annapurna and Dhaulagiri ranges, Upper Mustang is one of the most culturally preserved and geologically unique places in the Himalayas. But here’s the catch—it wasn’t even open to foreigners until 1992. 

That’s right, a kingdom hidden in plain sight for centuries, guarded by rugged terrain and age-old customs. So, what’s it really like to step into this once-restricted realm? Let’s find out together.

Mustang Nepal: The Hidden Gem of the Himalayas

One of the few places where time seems to slow down is Mustang. Situated next to Tibet in the north-central region of Nepal, this region has managed to hold onto its ancient roots while slowly adapting to the outside world. Mustang is quiet, serene, and full of mystery, unlike the busier trails of Everest or Annapurna. Upper Mustang is truly a treasure within the Forbidden Kingdom of Nepal.

From the ochre cliffs carved with centuries-old caves to the deep gorges and high-altitude deserts, every inch of this place feels like a page from a forgotten storybook. And the views? Breathtaking. Snow-capped peaks rise in the distance, while below, the Kali Gandaki River slices through the landscape like a silver ribbon. This is the Himalayas—but not as you know them. Trekking here gives you the feeling of being part of something ancient and sacred.

Geologically, the region looks more like Tibet than Nepal. The green hills and rice terraces that most people associate with Nepal are in sharp contrast to its desert environment, red rock formations, and expansive wind-swept valleys. In addition to improving the hiking experience, this unusual environment highlights the rare biodiversity that has evolved in these harsh conditions in the Forbidden Kingdom of Nepal. 

The Hidden Kingdom of Lo Manthang

At the heart of Upper Mustang lies Lo Manthang, the walled capital of the former Kingdom of Lo. Often referred to as the Hidden Kingdom of Lo Manthang, this town is where history whispers from every corner. Built in the 14th century, Lo Manthang is home to ancient monasteries, palaces, and labyrinthine alleys that haven’t changed much over the last few hundred years.

The walls that encircle Lo Manthang are not just physical barriers; they symbolize the protection of a culture and way of life that has remained unchanged for generations. As you walk through the city gates, you’ll be greeted by whitewashed mud-brick houses, prayer wheels spinning in the breeze, and locals wearing traditional Tibetan attire- a true cultural essence of the Forbidden Kingdom of Nepal.

The King’s Palace stands proudly in the town center—a simple but significant structure that has watched over this ancient community for centuries. Though the monarchy is no longer officially recognized, the king remains an important spiritual and cultural figure.

Ancient gompas (monasteries) like Jampa Lhakhang and Thubchen Gompa are living repositories of Buddhist teachings, adorned with vibrant murals and prayer flags. The sheer spiritual energy of the place makes Lo Manthang not just a destination, but an experience.

The Pulse of Ancient Tibetan Culture in Mustang

One of the most striking features of Upper Mustang is how deeply it is steeped in Tibetan culture. This isn’t by accident—Mustang once formed part of the ancient Tibetan kingdom, and the cultural ties remain incredibly strong. Experiencing the Ancient Tibetan culture in Mustang is one of the most enriching parts of the journey.

Everything from the architecture and language to the food and festivals reflects Tibetan influence. Most residents speak a dialect closer to Tibetan than Nepali, and their daily practices are rooted in Tibetan Buddhism. Every village you pass through has its own chorten (stupa), mani walls inscribed with prayers, and prayer flags fluttering in the wind.

The Tiji Festival is one of the cultural highlights in Mustang. Held annually in Lo Manthang, this three-day celebration tells the story of a deity who defeated a demon to save the kingdom from destruction. Monks in vibrant masks and robes perform ritual dances that captivate visitors and locals alike. Attending this festival gives you a rare glimpse into an age-old spiritual performance that’s been preserved for generations in the Forbidden Kingdom of Nepal.

What You Need to Know About Restricted Area Trekking in Nepal

Getting to Upper Mustang isn’t as simple as picking a trail and heading off. Because of its historical and strategic importance, Upper Mustang is designated as a Restricted area trekking in Nepal. This means that independent trekking is not allowed. You’ll need a special permit and must be accompanied by a registered guide or go through a licensed trekking agency.

The restricted area permit costs around USD 500 for the first 10 days and an additional USD 50 for each extra day. While this might seem expensive, it plays a crucial role in maintaining the cultural and ecological balance of the region. The limited access has helped protect Mustang from over-tourism and commercial exploitation, which is vital to preserving the Forbidden Kingdom of Nepal.

Moreover, trekking with a guide ensures your safety and enriches your understanding of the local culture. These guides often come from Mustang itself, providing insider knowledge and stories that you wouldn’t get otherwise.

Trekking Routes and Itineraries

Most treks to Upper Mustang begin in Jomsom, a town that’s accessible via a short flight from Pokhara. From Jomsom, the trail ascends through the village of Kagbeni—the official entry point into Upper Mustang. From there, the route winds through arid landscapes, riverbeds, and remote settlements, eventually reaching Lo Manthang.

If you are wondering about how to travel from Nepal to Jomsom. A typical itinerary lasts between 12 to 15 days. Here’s a quick look:

• Day 1–2: Kathmandu to Pokhara to Jomsom
• Day 3–6: Trek from Kagbeni to Ghami
• Days 7–9: Explore Lo Manthang and the surrounding caves
• Days 10–12: Return via a slightly different route

Side visits to mysterious cave complexes, such as the Chungsi and Jhong Caves, which are thought to have been utilized for meditation by monks and sages in the past, are possible. These undiscovered treasures enhance your visit to Nepal’s Forbidden Kingdom.

For those short on time or physical stamina, jeep tours are available, allowing for quicker access while still offering an immersive experience. These tours usually follow the same route, with stops at major cultural and natural landmarks.

Best Time to Visit Upper Mustang

One of the most appealing aspects of trekking in Upper Mustang is its accessibility even during the monsoon. Thanks to its location in the rain-shadow area of the Himalayas, the region remains dry and ideal for trekking from June to August, when most of Nepal is drenched.

However, the best times to visit are:

• Spring (March–May): Clear skies, blooming wildflowers, and mild weather
• Monsoon (June–August): Perfect for those wanting to escape the rain elsewhere in Nepal
• Autumn (September–November): Crisp air, great visibility, and post-harvest celebrations

The winter months (December to February) are less ideal due to cold temperatures and limited services, though the trails are quiet and peaceful for experienced trekkers. Each season brings its own charm to the Forbidden Kingdom of Nepal.

Accommodations and Local Hospitality

Upper Mustang doesn’t offer luxury resorts, but it does offer genuine warmth and cultural immersion. Most trekkers stay in teahouses or homestays that are clean, simple, and rich in local flavor.

Meals typically consist of dal bhat (lentil soup with rice), tsampa (roasted barley flour), thukpa (noodle soup), and Tibetan bread. Dining with locals offers insight into their way of life and stories passed down through generations in the Forbidden Kingdom of Nepal.

Evenings are often spent gathered around a yak-dung stove, sipping salty butter tea and exchanging stories. These shared moments are often what trekkers remember most.

How Do Isolated Trekking Routes in Nepal Compare

Nepal is home to some of the world’s most iconic trekking routes, but the Remote trekking destinations in Nepal each offer something unique. What sets Upper Mustang apart is its untouched culture and desert-like landscapes that feel more like Ladakh or Tibet.

Mustang offers quiet, genuineness, and the opportunity to see a vanishing world, in contrast to the marketed routes of Everest or Annapurna. It is more about adopting an ancient way of life than it is about climbing a high-altitude peak.

Mustang is the perfect hike for you if you prefer significant encounters over crowded perspectives. It challenges your perspective, slows your pace, and leaves you with memories that linger far longer than photos.
