Welcome! You’ve just happened into the world’s largest cave, a world in itself. At more than 200m high, 150m wide and 5km long, the Hang Son Doong cave in Vietnam is so big it has its own river, jungle and even climate!
Australian photographer John Spies – who runs an excellent guesthouse called Cave Lodge in Thailand – spent a week photographing the cave’s natural wonders and the handful of tourists who can afford to pay up to $3000 to marvel at its beauty. Some of the places he visited can only be accessed using kayaks or skilled climbing techniques, making each location a rarely seen treasure earned by very few. It’s absolutely awe-inspiring to gaze at these stunning images of the otherworldly realms hidden deep beneath the sunlit surface.
