Indigenous Eyes Ecological Park and Reserve is a 1,500-acre nature reserve that sits incongruously inside the Puntacana Resort and Club complex. The park protects twelve freshwater and brackish lagoons connected by a network of boardwalks and jungle trails. The largest lagoon is fed by an underground river and is clean enough for swimming — a genuine alternative to the saltwater beach if you want to cool off differently.
The trail system winds through dry tropical forest with good birdwatching — iguana, hutia, and at least 30 resident bird species including the Hispaniolan parakeet. Guided tours leave from the park entrance; self-guided entry is also available. It is one of the few places in the Punta Cana area that offers something genuinely ecological rather than constructed.
