What is Tu San Canyon?
Tu San Canyon is a dramatic gorge carved by the Nho Que River at the foot of Ma Pi Leng Pass. With cliffs rising up to 800 meters high and stretching over 1.7 kilometers, it is recognized as the deepest canyon in Southeast Asia. This natural wonder is part of the Dong Van Karst Plateau Geopark, a UNESCO Global Geopark, which highlights the unique geological and cultural heritage of Ha Giang province.
