Internationally, rapids are classified on a scale of Class I to VI according to their difficulty (VI usually being impossible to tackle and requires portering the raft along the river bank). There are no age limits for rafters, the only requisite is a taste for adventure.

The Vilcanota or Urubamba River, which runs through the heart of the Sacred Valley in Cuzco (Cusco), features some areas that are highly popular amongst rafters.

One stretch between Calca and Urubamba and another between Huambutio and Pisac both feature rapids rating Class II and III. A third stretch downstream from Ollantaytambo features Class III and IV rapids. The river is rafted from May to October.

The Apurimac River, which has only recently been added to the rafting circuit, is a unique experience due to its landscapes and difficulty. The river features Class III and IV rapids, while the trip takes three to four days. Expeditions set off from the city of Cuzco - recommended for experts.

The best season for these adventurers is from December to April, which is the ideal season to feel the exciting sensation of rafting down the river in a rubber dinghy.  

You'll admire the great scenery - Inca (Inka) bridges and constructions on the sides of the mountains.
