28 Stunning Photos Of The World’s Largest Cave

Real Underground Kingdom That Has Existed for Millions of Years Went Unnoticed, Until Recently...

In 1991, Ho Khanh, a local farmer was out gathering wood in the dense jungle of Vietnam’s Phong Nha-Ke Bang National Park, when he stumbled upon an enormous cave entrance. The roar of a rushing stream and the whistling sound of wind in the cave can be heard through the entrance located in a limestone cliff.

According to Khanh, it “felt like something from the underworld.” He soon forgot the cave’s location until he met British spelunkers exploring the area, some 20 years later. He began looking for the cave entrance again, which he found in 2008. The following year, he led an international team of scientists from the British Cave Research Association, led by Howard and Deb Limbert, in exploring what is now known as Son Doong Cave, the largest cave in the world.

Below are 28 stunning photos that capture the cave’s surreal, massive beauty. Enjoy!

The name “Son Doong” cave means “mountain river cave.”

Son Doong was created 2-5 million years ago by river water eroding away the limestone underneath the mountain.

A part of the ceiling, where the limestone was weak, collapsed and created huge skylights.

The cave is over 5.5 miles long. It has a jungle and river, and could fit a 40-story skyscraper within its walls.

The first expedition (from 10 to 14 April 2009) into Son Doong Cave was stopped by a 200-meter high calcite wall that the spelunkers dubbed the “Great Wall of Vietnam.”

The following year, a team successfully traversed the rock wall and were able to reach the end of the cave’s wall, officially determining Son Doong to be largest in the world.

The biggest chamber of Son Doong is more than 3.1 miles long, 660 ft high, and 490 ft wide.

The cave is also home to some of the world’s tallest stalagmites which tower 260 ft in the air, and limestone “cave pearls” (the size of baseballs) can be found on the cave floor.
