8:00 AM - You will start today an amazing trek through the unique Dong Van Karst Plateau, included in the UNESCO Global Geoparks Network since 2010. Located in the northernmost province in Vietnam, nearly 80% of the geopark is covered by limestone, high mountains and deep canyons, providing the area with a temperate climate ideal for trekking. In the 1920s, the French colonists set up one of the biggest fortresses in northern Vietnam at the highest point of the mountain dominating Dong Van town. The area is rich with history and geological wonders. You will stroll around the frontier between China and Vietnam, visiting remote villages living on the border, learning about the different aspects of the H’mong and Tay ethnic minority groups. One of the highlights will be the discovery of Thien Huong, a 100-year old village sitting on the mountainside with traditional Tay houses. You will return to Dong Van around 5pm, the end of the tour. Physical activities: 15-17km of trekking Meals: Lunch
