Well, it's easier than you think. All you need to do is to book a plane ticket to Rainbow Mountain in Peru. Rainbow Mountain is a beautiful natural wonder. It lies in the Andes in Cusco. Its name suggests the mountain has different colors. But why is it in yellow, green, red, and purple? The reason is the ice that covered the area centuries ago. When it started to melt, the water mixed with the minerals in the ground and turned the earth into many colors. If you plan your trip to the mountain, try to go during warmer months when there is less rain or snow. Rain or snow makes the climbing tougher and the colors will look less beautiful. The best time is from March to November, when there are blue skies and 返回目录 7 pleasant weather. At the same time, visit it in the morning or evening, either right after sunrise or right before sunset. Very sunny days may make you not take nice photos. To get to Rainbow Mountain, you should first travel to Cusco—a province in the south of Peru.Then you can take a drive to Qesoyuno. From there you can start the journey on foot. It takes about a two-or-three-hour walk to the top. This is really the best way, but it is very challenging. Because the mountain sits at a very high altitude about 5,200meters above sea level. So bring enough water and take your time. 返回目录 8 11. Why does Rainbow Mountain have different colors? ______________________________________________________________________ 12.
