The Inca Trail is a 20 mile one-way trek to Machu Picchu. The route typically takes about 4 days and a guide is required by law. While the route starts along the rushing Urunamba River, it climbs over Warmiwanusqa pass at 13,780 feet and then traverses numerous other ruins before reaching Machu Picchu.
To reach the hiking trailhead, start by flying into Lima and the transfer to a flight to Cusco. Typically, you will meet your guide in Cusco who will then transport you by bus for 37 miles to the trailhead at Ollantayambo. Make sure to bring lots of small local currency for tips and small purchases along the way.
Tip: May is the best time to go!
