Welcome to the “Roof of Indochina”. Up here in the far north, the mountains literally touch the clouds, and the steep hillsides are carved into dramatic, sweeping rice terraces. Trekking through the valleys of Sapa means walking alongside local Hmong and Red Dao people in their brilliant traditional clothes, passing grazing buffaloes and hidden waterfalls. The air is crisp, the culture is rich, and the views are simply out of this world.
