When visiting Ha Giang, you must see Tu San Alley, which is different from the "first majestic landscape" and is a must-see attraction. The Nho Que River winds its way through the canyon, which is a work of art in itself because of its flowing greenness and impressively high walls. Coming here will allow tourists to experience the natural beauty of Ha Giang's heaven and earth, try out new things, and take home the best pictures.
