Underground Epic in Hang Son DoongQuang Binh Province, Vietnam

Imagine a cave so big it could house an entire New York City block of 40-storey skyscrapers; a subterranean system so vast it creates its own weather system and is home to a micro-ecosystem of lakes, rivers and concealed jungle. First explored in 2009 and later officially declared the largest cave in the world, Hang Son Doong in Phong Nha Ke Bang National Park, north-central Vietnam, is a geological marvel only recently opened to the public.

Join a seven-day expedition led by experts from the British Cave Research Association and be one of the first to discover the secrets of this fascinating network of limestone chambers, karst pinnacles, stalagmites and stalactites. Wade through thigh-deep water by torchlight, examine 350-million-year-old fossils and keep your eyes peeled for white spiders and shrimp. A Boeing 747 could comfortably fly through the largest cavern but you’ll make the trek on foot with a team of porters and guides, who will take you to places that experience less foot traffic than Mount Everest.
