If you’re seeking a hidden gem far from the crowds – a place where raw nature dominates the landscape – then Tu San Abyss Alley in Ha Giang, Vietnam, belongs on your bucket list. Known as the deepest canyon in Southeast Asia, this stunning natural wonder offers an unforgettable journey through jagged cliffs, turquoise rivers, and remote mountain villages.
What is Tu San Abyss Alley?
Tu San Abyss Alley is a majestic canyon carved by the Nho Que River, located near the famous Ma Pi Leng Pass in northern Vietnam. The cliffs here rise more than 800 meters high, creating a narrow abyss nearly 1.7 kilometers long. This breathtaking gorge is one of the most dramatic geological formations in the country and still largely untouched by mass tourism.
For centuries, it remained inaccessible, hidden within the rugged mountains of the Dong Van Karst Plateau, a UNESCO Global Geopark. Today, it’s one of the most photogenic and awe-inspiring destinations for travelers who dare to explore Vietnam’s far north.
When is the best time to visit?
The best time to visit Tu San Abyss is between September and March, when the weather is dry and cool, and the Nho Que River turns a vibrant jade green. During this period, visibility is high, perfect for photography and outdoor activities like kayaking or boating.
