Is the country's most consistant river, with two exciting rafting routes that wind past great scenary, and can be run year round. The Tucurrique (class III) section of the Reventazón is easy enough for a first rafting trip.

The Pascua section (class IV-V), on the other hand, is the wildest rafting route the country has to offer, which is why some rafting experience is required to run it.
