Asia is too massive and diverse to conceptualise as a single digestible travel "destination". Even defining the borders of this continent is difficult - from the mountains to the Black Sea in the west, to the snow fields of Siberia in the east, there are more people and cities in Asia than outside of it.
The world's highest point, Mount Everest, lies within Asia along the border of Tibet and Nepal soaring 8,848m (29,028 ft) above sea level. Its lowest point is the Dead Sea, located at the meeting points of Israel, the Palestinian Territories, and Jordan, whose surface is 400m (1,312 ft) below sea level. Asia's longest river is the Yangtze, which runs 6,300km (3,915 miles) through China, all the way from the high Tibetan Plateau to Shanghai. Its largest lake is the 386,400km² (149,200 square miles) the Caspian Sea, which is surrounded by several Central Asian nations.
