When thinking about the Amazon Jungle, Brazil may first come to mind—and rightly so, as the largest portion of the rain forest is indeed in that country. However, the Amazon also makes up 60 percent of Peru’s land. Experience this fantastic landscape at Manu National Park, a UNESCO World Heritage Site and Biosphere Reserve. Try to spend a minimum of five days in the park, keeping in mind that the farther into the jungle you go, the more likely you are to see a wide variety of wildlife. Given that the park encompasses microclimates that range from more than 13,000 feet above sea level down to 984 feet, you will find a great diversity of vegetation, birds (800 species), and mammals (200 species) here. Not to mention butterflies—an incredible 1,300 butterfly species live in the jungle.
