Packed with dramatic glaciers and glistening lakes, Torres del Paine National Park is also home to spectacular animals and plants. At the bases of some of the world's most breathtaking mountains, guanacos graze in grassy fields. The Torres (towers) del Paine are usually hidden behind gray clouds. Occasionally, these steep granite peaks can be seen by visitors. Sometimes, they even make a challenging route for daring climbers. (GETTY IMAGES)
