Lang Son
Lang Son is a border province of China, situated in the northeast of Vietnam, approximately 160 kilometers from Hanoi. Historically, it has served as a strategic crossroads for trade with China and a vital link between the northeastern provinces and the port of Hai Phong. Lang Son's significance also extends to its military history: during the colonial era and the Indochina War, it was a key site for fierce battles, particularly along the famous RC-4 colonial road connecting Lang Son to Cao Bang. Notably, battles like Dong Khe and That Ke marked this region as a barrier that delayed Chinese troops from advancing into Vietnam.
Today, Lang Son is renowned for its mountainous terrain and stunning limestone formations, as well as for being home to several ethnic communities, including the Tay and Dao. The province is a fascinating blend of history, culture, and natural beauty, making it a highly recommended stop on a tour of Vietnam's northeast, particularly from Halong Bay.
