World's Largest Cave, Son Doong, Hosts First Public Tours (And The Photos Are Unreal)

Posted: Updated:

The Son Doong Cave in Vietnam is the biggest cave in the world. It's over 5.5 miles long, has a jungle and river, and could fit a 40-story skyscraper within its walls.

But nobody knew any of that until five years ago.

The newly discovered cave has been touted as the largest in the world, although other caves vie for the title of longest (Mammoth Cave in Brownsville, Kentucky nabs that title with about 400 miles of passageways) and deepest (Krubera Cave in the nation of Georgia).

A local man discovered the cave entrance in 1991, but British cavers were the first to explore it in 2009. Tour company Oxalis has been running trial tours of the cave since last summer. According to their website, there is currently "no availability" left for 2014 tours, but the schedule for 2015 will be posted "later this year."

The lucky few who have entered Son Doong so far, like photographer John Spies, have emerged with some amazing photos.







The man who discovered Son Doong didn't go in because the entrance he found had too steep a drop. On tours, visitors rappel 80 meters to enter Son Doong.

On their first night inside the cave, visitors camp near Hand of Dog, a humongous stalagmite that looks like a dog's paw.

The roof of the cave collapsed centuries ago, allowing a lush jungle to take root. Monkeys and flying foxes live in what explorers named the Garden of Edam.

Fields of algae from ancient pools blanket parts of the cave's interior.

Son Doong is a jackpot of rare cave pearls. The pearls form over hundreds of years as water drips down, dries up and leaves layers of calcite crystals on grains of sand.

Scientists have discovered never-before-seen plant species around Son Doong's waterfalls. Oh, and there's a whole river in there, too.
