Name and history of Hai Van Pass

Hai means the Ocean, Van is the Cloud. So, Hai Van Pass refers to the Ocean – Cloud Pass because it is near the sea and on the top often gets cloudy.

Hai Van pass is also known as the Ai Van pass because there is a gate (Ai) on the top of the pass, and Deo May – Cloud pass.

According to historical records, before the year of Binh Ngo (in 1306), the land with Hai Van pass belonged to two regions of O and Ri of the Champa kingdom (Chiem Thanh). After being cut by Champa King Che Man to propose to Cong Chua Huyen Tran (Tran dynasty) in 1306, Hai Van pass is the boundary between Dai Viet (one former name of Vietnam) and Chiem Thanh.

About a century later, in 1402, the Ho dynasty brought troops to fight Chiem Thanh, forcing the king of Chiem Thanh to cut the land of Chiem Dong and Co Luy to make peace. Since then, the whole area with Hai Van pass belonged to Dai Ngu (another old name of Vietnam).

Later, during the French colonial period, Hai Van pass was built. However, the road was built very narrow and dangerous, and many beasts and looting took place at that time. Therefore, the French built more winding rail through this mountain.

During the period after 1954, because the road was too narrow, traffic accidents usually occurred. Thus, the government at that time set up 3 traffic checkpoints: 1 in Lang Co, 1 at the top of the pass, and 1 in Lien Chieu to control traffic volume. In 1966, the US Army allowed widening the road through the pass. The street was larger, so when passing through the pass, there is no longer waiting for other vehicles at 3 checkpoints. Although the big road has done, the accidents on the Hai Van pass are still an obsession for the drivers because of the twisting street.

Therefore, in 2000, Vietnam started to build a tunnel through the Hai Van pass to ensure traffic safety when crossing this place. In 2005, the construction through the mountain opened, creating favorable conditions for the safe North-South movement.

Today, although there is a tunnel connecting Lang Co bay and Da Nang City, tourists still want to go over the Hai Van pass to conquer its incredible beauty, which is set up by the mountains, clouds, and ocean.
