Punta Santiago, Puerto Rico
The Humacao Nature Reserve, on Hwy P3 between Humacao and Punta Santiago, Puerto Rico, is a small, free natural park with trails, bathrooms, souvenirs, and the opportunity to kayak through mangrove swamps (for a fee).
We decided to take an hour-long hike on our way to look at some properties in Vista del Mar, a huge resort community a few miles South of Humacao on the sea. It was serenely quiet and oddly beautiful as we made our way down the soggy road looking for our first iguana, said to grow up to 12 feet in length!
We saw several large lizards (up to 18 inches long), a large beetle of some type, a few birds, but no iguana, turtles, manatees, or monkeys along our journey. The park is well worth the detour if in the area, but bring some stable shoes, ones that you do not mind getting muddy and soggy along the way.
