From an almost‑lost world concealed in a Vietnam jungle to an off‑the‑grid Arctic basecamp with a year‑round population of zero, there are still nooks and crannies on our planet where few have ventured. Check out six of the most remote places on Earth – but don’t expect Google Maps to help you here.
Trek inside the largest cave on Earth, Hang Son Doong. Hidden in Vietnam’s Phong Nha‑Ke Bang National Park, the “Mountain River Cave” opened to the public in 2013 and is so vast that it has two jungles, a river and multiple microclimates. Adventure tour company Oxalis operates the only expeditions, in partnership with the British Cave Research Association.
