Considered by many to be the most famous hike in South America (and quite possibly the world), the Inca Trail to Machu Picchu offers adventure seekers the opportunity to mix history with breathtaking Andean vistas and the rugged Peruvian outdoors. The trail head begins at what's known as KM82, winding through a variety of landscapes including lush forests, subtropical jungles and mountainous elevations of up to 4,200 m (13,780 ft). Along the way, you'll be treated to other Inca ruin sites including Runkurakay and the stunningly tiered Wiñay Wayna, culminating in an indescribable early morning arrival at the Lost City of the Incas itself. Though there are several trail options to choose from (between 2 and 7 days), the most popular by far is the 4 day Inca Trail Hike which, due to limited availability, should be booked well in advance. It might not be the most secluded trek you've ever been on, but for such an experience we highly doubt you'll mind the company.
Location:Machu Picchu Historical Sanctuary, along the Urubamba River, Peru
