This cave is “a mass of gobsmacking statistics,” says Liz Boulter in The Guardian: “it’s big enough to swallow a street of tower blocks; a jumbo jet could land in it; it has beaches, a river, jungle, even clouds.” At 9km long, 200 metres high and 150 metres wide, Son Doong -- located in the Phong Nha-Ke Bang national park in central Vietnam -- is the world’s biggest cave.
Son Doong has become “one of the hottest tickets in travel for in-the-know adventurers,” writes Lonely Planet. “Negotiating its 5km-long cavern is superbly exciting, but guided tours are limited and beyond the budget of many.” “More people have stood on the summit of Mount Everest than have witnessed the surreal beauty inside these enormous chambers,” notes CNN. And the national park has a lot more to offer, explains Boulter: “high limestone peaks, waterfalls, deep river gorges, virgin forest – and at least 400 more caves.”
