Peru's rivers range from the slow and muddy to the quick and clear. The rivers are beautiful and course through every region of the country. The Urubamba River cascades down the Sacred Valley and is one of the best places to go rafting, as some sections have Class III-IV rapids. In contrast, the Amazon and Tambopata rivers meander leisurely through the Amazon Jungle. Exploring Peru's rivers can involve searching for wildlife, visiting indigenous villages, or charging epic whitewater.
