Within the property one of the most interesting native species is the Howler Monkey. These large, brown monkeys communicate through very guttural shouts that can sound otherworldly at times. They typically travel in packs and can often be seen traveling through the canopy while looking for food.

Another interesting creature found on the property is the Green Iguana. These creatures have a variety of colors in the area ranging from brown to almost white. They can be found scurrying around on the ground or climbing trees.

There are also many interesting species of birds on the property. Hawks and vultures can be seen soaring on the currents generated from the hills. Green parakeets generally fly at lower altitudes in large flocks. Many other species can be found as well.

Part of the property actually overlooks the Parque Marino Las Baulas, the most prolific nesting ground of the Leatherback Turtle. This endangered species crawls ashore in a special night time ceremony to lay hundreds of eggs in the sand before heading back to sea.

Between Playa Grande and Tamarindo, the estuary holds a number of interesting species including saltwater crocodiles. A panga can be hired to tour the estuary to see crocs and many interesting bird species.

For those interesting in aquatic wildlife, sport fishing boats can be chartered in either Tamarindo or Flamingo. Excellent captains abound who can fish for many native species of game fish including Blue Marlin, Black Marlin, Sailfish, various Tuna species, Roosterfish/Wahoo, and Mahi Mahi/Dolphin.

Excellent diving can also be found near Colinas Doradas with dive boats leaving from both Tamarindo and Flamingo as well. One popular spots is the Catalina Islands, west of Flamingo. Good snorkeling and spear fishing can be found nearby at Pirates Bay.
