Some say it is the most awesome opening on Earth! Hang Son Doong, in Vietnam, is the world’s largest cave and it is filled with unimaginable beauty.
Known as “Mountain River Cave,” it is one of 300 caves in the Phong Nha-Ke Bang National Parkcave system, a UNESCO World Heritage Site, but it is without a doubt the most remarkable.
Australian caver and photographer John Spies knows the cave well — he’s lived inside it for a week at a time, capturing its many wonders. He and his partner run a guesthouse called Cave Lodge, located right near the the caves, They also offer guided tours.
Spies has been exploring caves for more than 30 years. He knows how to find them — discovering many never before seen by humans. He knows how to navigate around their incredible formations and wind through their convoluted passages. He knows how to photograph their drama.
Son Doong’s ceilings soar to more than 200 metres high in places. The entrance is quite small. You must descend 80m down a steep wall, using harnesses and ropes to enter.
