The Inca Jungle Trekking adventure to Machu Picchu is one of the most popular alternative treks to Machu Picchu, and can be done in 4 or 3 days. The Inca Jungle Adventure is a mixture of biking and hiking and follows a recently discovered Inca trail. You will stay in basic hostels in small towns along the way so you don’t have to worry about carrying extra gear and getting cold while camping – and yes there are showers along the way! Some hot, some cold! http://ping.fm/el9cC
