Before you go
Where is the best place to see South American River Dolphins?
Anavilhanas National Park
In Anavilhanas National Park, Brazil, the chance of seeing all 2 (amazon river dolphin and tucuxi) on the same day is about 10%, the highest of the 2 parks where all of them live, and over a three-day visit it rises to about 50%. Next come Amacayacu National Natural Park (about 10% a day). It multiplies each animal's daily chance, as if they were independent, so read it as a rough guide.
