Have you ever dreamed of walking through a land where time stands still—where dusty trails lead to ancient walled cities and the air hums with centuries of untold stories? Welcome to Upper Mustang, also known as the Last Forbidden Kingdom of Nepal.
Hidden in the northern Himalayas, Upper Mustang is like a slice of Tibet tucked inside Nepal. Until 1992, it was closed to outsiders. Even now, only a few trekkers venture here. But those who do are rewarded with barren beauty, centuries-old monasteries, and cave homes carved into cliffs. It’s not just a trek—it’s time travel.
But planning your trip can feel overwhelming—permits, maps, changing trail conditions, and finding the right guides. That’s where Eco Himalaya Treks steps in. With years of hands-on experience in Mustang, they’ll take care of every detail so you can simply enjoy the adventure. Let’s dive into what makes this trek unforgettable.
Why Trek the Last Forbidden Kingdom of Nepal?
Trekking in the Last Forbidden Kingdom of Nepal feels like flipping through pages of a living history book. Upper Mustang was once a separate kingdom, ruled by its own king and untouched by the outside world. Even today, its Tibetan-style villages, red-walled monasteries, and cliff-carved caves preserve centuries of heritage.
What makes it even more fascinating is the stark contrast between its surroundings and traditional Himalayan treks. There are no green forests or big rainforests here. Instead, picture desert-like valleys, rocky cliffs, and arid riverbeds set against a sky of infinite blue.
The actual magic? Prayer flags fluttering in the wind, ancient chortens lining your path, and the chance to walk into Lo Manthang—a walled city that still feels regal and spiritual. Whether you’re a seasoned trekker or a curious explorer, the Upper Mustang trek offers rare cultural depth with breathtaking views.
Best months to explore? Trek between late March to early November, especially May and October, when skies are clear and trails are dry.
