Our tour guide will pick you up at your hotel in Hanoi old quarter around 7:30- 8:00 am, transferring you to Lang Son. We will start by driving in the direction of the Chinese border for about 3 hours, before stopping at Chi Lang Pass a 20kmlong gorge created from a narrow valley between two mountains. This place occupies an important position in Vietnamese history, being the place of many victories against various Chinese invasions over the centuries and millennia, as far back as 981AD. As such it bears the reputation of Vietnam’s strongest citadel and bastion. Here you will have roughly an hour to walk around and explore the area around the Quy Mon Quan Gate, which translates as “The Gate of Monsters”, named for the many invasion forces that would spill through the pass over the course of history only to be beaten back by stalwart Vietnamese defenders.

After lunch at a local restaurant in Dong Dang, you will continue your trip into the pass, stopping to visit Mother’s Temple and Dong Khe – an important historical site where The Battle of Dong Khe was fought during the First Indochina War. In fact, this was the very first battle of the Indochina Wars, and the fighting here took place through September and October 1950, ending in a resounding victory for the Viet Minh. In the evening you will get to enjoy dinner and overnight rest in a local homestay owned and operated by a local Nung family.
