Asia is almost too massive and diverse to conceptualize as a digestible travel "destination". Even defining the borders of this continent is difficult - from the mountains around 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. Asia's highest point is Nepal's and China's Mount Everest, which rises to 8,848 m (29,028 feet) above sea level. Its lowest point is Israel's and Jordan's Dead Sea, whose surface is 400 m (1,312 feet) below sea level. Asia's longest river is the Yangtze, which runs 6,300 km (3,915 miles) through China. Its largest lake is the 386,400 sq km (149,200 square mile) Caspian Sea, which is surrounded by several central Asian nations. Asia is bounded by the Pacific Ocean to the east, by Australia to the southeast, and by the Indian Ocean to the south. It is bounded by the Red Sea to the southwest, by Europe to the west, and by the Arctic Ocean to the north. Beauty culture and Natural resources. Those are the two words that will stay with you during your trip to Asia - most of world heritage spots are listed. Apart from being the world's largest and most populous continent, Asia is dynamic, modern and progress in many different ways. It covers 8.6% of the Earth's total surface area (or 29.4% of its land area) and, with almost 4 billion people, it contains more than 60% of the world's current human population
