The Nho Que River, located in the northern region of Vietnam, is renowned for its striking natural beauty. Flowing through the Ha Giang province, the river winds its way through the Dong Van Karst Plateau, a UNESCO Global Geopark. The most famous stretch of the Nho Que River is where it cuts through the Tu San Canyon, one of the deepest canyons in Southeast Asia, creating an awe-inspiring landscape of sheer limestone cliffs and verdant greenery.
