| Animal | How often | Tip |
|---|---|---|
| Three-toed sloth | Very common | High in the canopy; you need a scope or a guide. |
| White-faced capuchin | Very common | Bold near the beaches. Keep food sealed. |
| Squirrel monkey | Frequent | Central Pacific endemic subspecies; moves in troops. |
| Mantled howler monkey | Frequent | Heard before seen. |
| Green and black iguana | Very common | Sunning on rocks and beach edges. |
| Agouti, coati, raccoon | Frequent | Near trails and picnic areas. |
| Toucans and aracaris | Frequent | Early morning. |
| Two-toed sloth, kinkajou, red-eyed tree frog | Night only | The park is closed at night; these are seen on the night tour on a private reserve next door. |
No animal is guaranteed. A guide raises the odds because they know where each animal rested that week.
