What a great trip for the active Singular! Hiking, Biking and Kayaking through some of the most spectacular landscapes in the world! I've got mine booked and I think there are still a few spots open (last I checked) But you need to book right away to insure that your trail permits are approved. Because of the endangered ecosystem, travel is very regulated and visits to Machu Picchu may be suspended in the near future altogether! Come on folks, this is the chance of a lifetime! To visit the remains of the Inca civilizations through the jungles and mountains of south america!  It's not a vacation, it's an ADVENTURE!
