In order for Sơn Đoòng to become famous around the globe, the project to bring Sơn Đoòng image in the form of 360° to the world by National Geographic in 2015 should be mentioned.

This project idea came from Martin Edstrom, a Swedish photographer who is currently working with National Geographic. On July 7, 2014, Martin contacted Oxalis Adventure with the idea of bringing 360° angles that no one has ever done at Sơn Đoòng Cave so that any reader has the opportunity to experience the majestic and unspoiled beauty of the world's largest cave in Quang Binh, Vietnam.

Oxalis management has authorized the implementation of the project from January 24, 2015 to January 30, 2015. With Oxalis's support in logistics, mobilizing the Porter brothers to transport 220kg of equipment for the project, the team of 7 photographers worked hard to create impressive images during the trip.

After Sơn Đoòng's first 360° sharp photo series was posted by National Geographic on their website, the product made a huge mark on readers around the world. The photo series has satisfied those who wish to conquer Sơn Đoòng once in their life without conditions to perform.

Sơn Đoòng 360 begins with the image of a stream in the middle of the vast valley - this is the road leading to Sơn Đoòng cave. On the computer screen, readers can drag the left or right screen to admire the spectacular 360-degree views. In addition, Martin also inserts the sound corresponding to each frame so that virtual tourists can listen to the mountain sounds extremely realistic and vivid. Tracing the 23 locations shown on the 3D cave map, we can admire more beauty inside the world's largest wonder Sơn Đoòng Cave.

According to Martin Edstrom, to be able to take beautiful 360° photos in the dark cave, the most difficult problem that the crew encountered was the problem of light.

"With regular photography or cinematography, the light only needs to be on one side. However, these are 360-degree photos, so the light needs to shine all around and always should be," Martin said.

As the Covid pandemic rages around the globe and people can't travel, Sơn Đoòng 360 has become the most attractive virtual reality tour. In 2020, The Guardian (UK) introduces nature tours that are easy to do at home with just a computer or smartphone. In particular, the majestic landscape of Sơn Đoòng has been included in the top 10 most visited virtual reality tours in the world.

There are still many world-class promotional projects that have been implemented during oxalis's past 10 years. Let's take a look at the articles below!
