Whether it is a day trip down the Urubamba's Sacred Valley, 4 days on the Rio Apurimac, or 7 days inside the Colca's 13,000 foot deep gorge, we met the best people doing these rivers on our last trip. All these rivers are a world - class challenge in deep, remote canyons of the Andes with peaks over 20,000 feet! The rivers alone are worth the trip but then there is the allure of this exotic culture, it's history, elaborate, temples, and resilient people.
