14 Bluest Waters in the Whole Wide World

Five-Flower Lake, Jiuzhaigou National Park, China

Spectacular waterfalls tumble into the brilliantly blue lakes at this UNESCO World Heritage Site in China’s Sichuan province. The park’s most famous attraction is the crystalline Five-Flower Lake—the startling blue water offers a window-like view to the bottom where fallen trees make a lace-like pattern on the lake floor. The water is so still and clear it mirrors the surrounding mountains and trees as well as the sky above.
