Literally "manatee park", Manati Park is the best-known park where you can swim with dolphins in the Dominican Republic, and also the oldest, inaugurated in 1996.
It is in fact a 210km² theme park housing 150 tropical species, including birds (parakeets, parrots, etc.), reptiles (the country's largest iguana breeding centre) and mammals, in superb gardens rich in orchids and other tropical plants.
