Hải Vân Pass



The Hải Vân Pass (Vietnamese: Đèo Hải Vân) is a coastal mountain pass in central Vietnam. It is located on the border between Thừa Thiên Province and Đà Nẵng.

The pass has a winding road over the top, and North-South Railway to the east along the coast. There is a small village at the top.

A new road tunnel was recently built under the mountains to alleviate traffic from the sometimes dangerous top road, and making it less of a chokepoint to north-south travel within Vietnam. It is the longest tunnel in Southeast Asia.
