Trai cave in Lac Son’s Tan Lap commune has been preserved to serve tourism and studying activities on the Hoa Binh Culture.

Located on the east side of an independent mountain on the bank of Lan stream, the 13m-deep cave has an arc-shape mouth of about 8m wide and 10m high. The cave is filled with sunlight and clear air during daytime.

According to Nguyen Thi Thu Hien from the Hoa Binh museum, the cave houses traces of the Hoa Binh Culture, the earliest of its type in the Red River basin. Since its discovery in 1975, various research and excavations have been conducted here, which unearthed over 5,000 artifacts. Most of the artifacts are shells of stream snails, tools and pieces of pottery, and rice, among others, which are the clearest evidence of a primitive wet rice farming in the Hoa Binh Culture.

In 2008, preservation work was conducted in the relic to serve both tourism and research purpose. In the coming time, together with a project on building an eco-urban, resort, and high-end entertainment complex in Tan Lap’s Quy Hoa commune, the cave will be further renovated to become an attractive tourist destination. Meanwhile, locals will be trained to turn local specialties into tourism products./.
