Located between the Tam Dao range and the end of the two arcs of Ngan Son and Bac Son, Thai Nguyen has a transitional terrain from the mountains to the plains, like the gateway to the Viet Bac highlands. Thai Nguyen is not far from Hanoi, only more than 70km from the capital city center with the expressway shortening travel time, but the mysterious atmosphere of the forest road still covers this place. It seems that people still do not know about this semi-mountainous place, but only when you go there will you know how valuable that "unknown" is.
