Explore Mat Than Mountain, a unique "Giant Eye" landmark in Cao Bang. Discover outdoor activities, cultural experiences, and stunning natural beauty year-round. Mat Than Mountain, also known as "God's Eye," is one of the most unique and stunning natural landmarks in the Non Nuoc Cao Bang UNESCO Global Geopark in northern Vietnam. Famous for its enormous natural hole that pierces through the mountain, this geological marvel resembles a "giant eye" and has become a captivating destination for nature lovers and adventure seekers.

A Unique Geological Wonder
Situated about 50 kilometers from Cao Bang city, Mat Than Mountain is set within a vast, picturesque valley. The hole in the mountain, which has a diameter of around 50 meters at its widest point, gives the mountain its other name—Thung Mountain or Phia Piot in the local Tay ethnic language. This striking natural feature is a highlight of the scenic area around Thang Hen Lake, a part of the UNESCO-listed Non Nuoc Cao Bang Geopark.


The mountain and its surrounding landscapes offer a dynamic experience, with the scenery changing dramatically with the seasons. Visitors can explore lush, green valleys in the dry season and enjoy boating on the serene waters that fill the area during the rainy season.

Seasonal Activities and Natural Beauty
Mat Than Mountain is an ideal destination for those looking for outdoor activities and tranquility. During the dry season, from September to March according to the lunar calendar, the valley surrounding the mountain is a perfect spot for camping, picnics, and leisurely hikes amidst fresh, vibrant greenery. In contrast, during the rainy season from April to August, the valley transforms into a vast, crystal-clear lake, providing opportunities for peaceful boating and fishing.

Visitors seeking a more immersive experience can also explore other nearby attractions. The Nam Tra Waterfall offers a beautiful cascade set in a lush landscape, while the Danh village, known for its traditional Tay stilt houses with yin-yang tiled roofs, provides a glimpse into the rich culture and history of the region.

A "Healing" Destination
Beyond its geological uniqueness, Mat Than Mountain has earned a reputation as a "healing" destination due to its serene atmosphere and the peacefulness it offers visitors. The combination of awe-inspiring natural scenery and tranquil activities like boating, fishing, and camping has made it a popular spot for those seeking a retreat from the hustle and bustle of city life.
