Asia’s Best Cave
“It is without a doubt Son Doong. It’s just so startlingly different than any other cave in the world. It’s huge and it has so many beautiful cave formations that you will never see anywhere else—plus two jungles. But if you go to Son Doong first, it will spoil you for any other cave in the world. We have had grown men crying down there.”

Get on this level!
On Preservation
“Oxalis arranges limited tours for just eight clients at a time. We just discovered Son Doong in 2009, so we are now trying to preserve it and keep it in pristine condition: we don’t want cable cars and mass tourism.”

Just go with the flow
For Beginners
“There’s another cave called Tu Lan, where we do one- to four-day tours. We swim through caves, and camp in the jungle. Most people who have done that trip say it’s the best thing they’ve ever done.”
