Not only attractive by the landscape, Khau Lieu Pass is also associated with many folk stories of the Tay and Nung people living around the area. Since ancient times, this has been an important trade route between villages. Before there were motorable roads, people had to follow steep paths to transport goods across the pass. Life attached to the mountains and forests has created many legends and memories about a road that was once considered the most dangerous in Chongqing. Khau Lieu Pass is also a historical place. During the war to protect the Northern border in 1979, this place was an important defense position with many fierce battles. At the top of the pass, there is still a stele marking the Khau Lieu victory in February 1979, reminding of the resilient spirit of Cao Bang's army and people during the war years. Today, this location not only has historical significance but also contributes to educating patriotic traditions for younger generations. Currently, traffic through the pass is more convenient than before, but Khau Lieu still retains its natural beauty. Soft curves, deep green mountains and peaceful space make this place an indispensable stop on the journey to explore UNESCO Non Nuoc Cao Bang Global Geopark. From the pass, visitors can continue their journey to Ban Gioc waterfall - one of the most beautiful waterfalls in Southeast Asia, or explore Nguom Ngao cave with its magnificent stalactite system. Khau Lieu Pass is not only a road connecting famous destinations but also a convergence of natural beauty, cultural identity and historical values of Cao Bang. Every turn, every mountain slope gives visitors a feeling of conquest and discovery. If you have the opportunity to come to Cao Bang, take the time to stop at Khau Lieu peak to admire the majestic nature, enjoy the fresh air and fully feel the beauty of one of the most memorable passes in the Northeast.

Ho Thang Hen

Thang Hen Lake, hidden behind the canopy of old forests and cat-eared cliffs, is a blue diamond-shaped lake with four seasons. The Tay people say it resembles the tail of a bee, so they call it Thang Hen ("bee tail" in the Tay language). Thang Hen is the largest freshwater lake among the 36 freshwater lakes in Tra Linh district. Although they are separated, they are connected by underground caves. The lake water is hazy jade green all year round, even during flood season - when other lakes in the same area are red with mud. The reason is because the lake's upstream is Thang Hen cave at high altitude. Water pouring out from the mouth of the cave provides a source of "clean water" for the lake. According to the legend of the Tay people, in the past, Cao Bang land had a handsome and intelligent man named Sung. After passing the exam, the king allowed him to return to honor his ancestors for seven days. Returning to his hometown, he married Miss Booc. He was so absorbed in his beautiful wife that he forgot to return to the capital. It wasn't until the night of Saturday that Mr. Sung suddenly remembered. He quickly said goodbye to his wife and ran back to the capital in the middle of the night. Mr. Sung ran 36 steps before falling, hitting his head on the mountain and dying. His 36 steps are 36 large and small lakes in the Thang Hen lake complex (now in Tra Linh district). As for the rock caves surrounding the lake, they were created by Mr. Sung's toes. Every year in September and October, Thang Hen Lake's water will be drained in just a few hours. Therefore, witnessing this strange phenomenon is extremely lucky. Even the indigenous people can only estimate the time and are not sure when the lake will dry up. When the water is barely scratched, people will race to the lake to catch fish, shrimp, and shrimp to eat. Big fish are the top "hunting" targets to grill for guests. Strangely, even though thousands of cubic meters of lake water dropped, the surrounding landscape remained unchanged. Therefore, many people compare Thang Hen Lake to a bag of water whose bottom has been punctured by someone. Local people spread word of mouth that the phenomenon of Thang Hen Lake drying up in just one night was a sea monster that had been imprisoned in the valley for many years. In the frenzy of being hunted, it used its claws to create underground caves vertically and horizontally. To enjoy the beautiful scenery of Thang Hen, you should not sleep late. When the sun just peeks behind the mountains is the best time to immerse yourself in the wonderland here. At this time, the lake surface is like a jade mirror covered with a white veil. Looming around are hidden mountains. The early morning scene here is strangely peaceful, completely separate from the hustle and bustle of the city outside. Thang Hen Lake area has steep rocky cliffs. On it, visitors can easily recognize wooden trees that are hundreds of years old and many varieties of wild orchids.
