Some of the Vietnamese caves are massive. The biggest cave in the world, Son Donng, is found in Vietnam, and at it's largest section you can fly a Boeing 747 through it with extra room to spare. I visited 3 or so caves while there and they were also all quite massive, we took boats to go into them.

The world's largest cave is so big that a Boeing 747 could fly through its largest cavern unscathed. It could fit a Manhattan city block complete with 40-story skyscrapers and has its own weather system that creates misty clouds hanging right above you.

And it wasn't explored until 2009.

Now that is a cave! I am almost tempted to add that to my bucket list!
