I had been living in Punta Cana for a few months when my parents came to visit. They are very keen bird and wildlife watchers and I was struggling for ideas of places in Punta Cana to show them. I came across the indigenous eyes park in the lonely planet guide book and thought we would give it a shot. We went ourselves, not through an organised trip and our taxi did struggle to find the actual entrance, but that only gave us an added bonus of finding the iguanas! There is a lovely enclosure which we were allowed into to get closer to and take photos of the iguanas.
When we finally found the entrance to the park I was surprised at the price, it really wasn't expensive and after spending several hours walking through to the Caribbean sea, I would say 100% worth every penny.
We didn't know about the lagoons you can swim in, so would recommend taking swim wear.
The paths are good, so if it is dry you can easily manage in flip-flops.
If you like wildlife then it is a must for the Dominican Republic. We saw lots of birds that are only found here as well as an osprey which we weren't expecting!
