Marvel at the spectacular views and well-preserved temples in the Sacred Valley, and learn firsthand about rainforest ecology and biology as you trek through the lush jungles of the Amazon basin. Only the smiles that greet you in each town are brighter than the sun glittering off snow-capped mountains and crystalline lakes (although the brilliantly-colored traditional clothing and handicrafts take a close second to both). Our tours ensure you see it all.
