The world’s third largest cave has “rooms” that stand 330 feet high and span 600 feet across. It’s so spectacular that it’s playing home to several upcoming blockbusters, including this summer’s Pan, and others the force compels us not to disclose. We hiked through the Vietnamese jungle to explore it.
Working as a National Geographic photographer is (thankfully) more than just panther attacks and paraglider crashes. Sometimes you get to explore the underground equivalent of "a previously undiscovered Mount Everest" like photographer Carsten Peter.
