The Pentagon Motor Group (PMG)’s Instagram data analysis was used to compile the list.

PMG analysed more than 7 million Instagram hashtags to find the world’s most stunning routes and divided the number of images of selected routes by their length.

With a length of 20 kilometres and 2,686 pictures per km, the Hai Van Pass came fourth in the list, behind the Great Ocean Road (Australia), Big Sur (California), and Jebel Hafeet (United Arab Emirates).

Jonathan Lingham, marketing director at Pentagon Motor Group, told the magazine: "Despite the looming question over international travel, road trips are still on cards, thanks to the luxury and convenience of our wheels."

"As there are so many driving holiday destinations around the globe, we were curious to find out which route is officially the most beautiful. It's great to see so many bucket-list-worthy road trips cropping up from all around the world — from the UK to Australia, and Norway to the USA — it proves that everyone can jump in their car and embark on an epic adventure,” he added.

According to Travel + Leisure, the Hai Van Pass was once dubbed “one of the best coast roads in the world” by Jeremy Clarkson, former host of UK motoring television programme Top Gear.

The website also recommended those travelling along the route slow their speed when weather conditions become foggy.

PMG’s search noted that the pass has become one of the most popular destinations for visitors to snap photographs on, with more than 55,000 photos taken at the site uploaded to Instagram.

The Hai Van Pass is approximately 20km long and 500m above sea level.

It is on National Highway 1A, some 80km from the heart of Hue to the south and more than 20km from the centre of Da Nang to the north, running across Bach Ma Mountain which stretches from the Truong Son range to the sea, creating a natural boundary between Thua Thien-Hue Province and Da Nang City.

The pass has lush jungle on one side and the sea on the other. The crooked road winding along the mountainside has been compared to a ribbon crossing heaven and earth.
