Lancang River Grand Canyon in Lincang, Yunnan

Lancang River Grand Canyon features a deep, long valley and fast-flowing river. Known as the Mekong in Southeast Asia, the Lancang flows 4,900 km through China, Myanmar, Laos, Thailand, Cambodia, and Vietnam, called the Danube of Asia. In spring, wild peach blossoms bloom in April against snowy mountains, with green highland barley adorning ancient villages. Ranked among China's Top Ten Most Beautiful Canyons in 2005, its dramatic terrain inspires awe, once crossed by tea-horse road merchants via zip lines.
