Rich with its lush tropical forests, subtropical jungles and thousand-year-old ruins, this trail encompasses all that is beautiful in South America. Considered by many to be one of the top five treks in the world, this 26-mile trail is well worth the visit. Travellers start their journey in the grassy mountains above the Urubamba River, walk along the winding roads that lead to the legendary ruins of Machu Picchu. Here in the "Lost City of the Incas," travelers will catch a glimpse of the spectacular paved stones, relics and tunnels.
A walk up Mount Kilimanjaro in northern Tanzania is a feat not only worthy of the photo albums, but worthy of bragging rights as well. Not only is Kilimanjaro the tallest mountain in Africa (at a whopping 19,336 feet), it is one of the biggest volcanoes on the planet, but don't worry it's dormant. Rising above the Indian Ocean, Kilimanjaro has three volcanic cones -- Kibo, Mawenzi and Shira. Just like the trek in Cajas National Park, this walk is best for those who can acclimate well to high altitudes. But the physical work is worth the workout. Along the six- to seven-day trek, you'll see the dormant craters, wild forests, gigantic rock formations and spectacular waterfalls.
If what you want out of a nice walk is an exotic world filled with wild animals, plants and fruit, the Amazon Jungle in South America is what you've been looking for. Depending on where in the jungle you venture to, you may be able to see howler monkeys, slinky jaguars, lazy sloths, buzzing hummingbirds and an assortment of colorful reptiles. But if travelling along any rivers, such as the Rio Negro, make sure to keep an eye out for alligators and piranhas. Some of the more adventurous travelers may also want to consider a night walk to see the truly wild side of the nocturnal jungle. But if you decide to venture out in the wild after nightfall, it's best to go with an experienced tour guide.
