One of my favorite parts of Puerto Rico is the incessant call of the Coqui each night. As soon as dusk falls the coqui come out of hiding and give a full chorus, even in the city. But at the rainforest, they are loud and comforting and perfect.
The Coqui give an enchanting call and round out the perfect Puerto Rican experience. If you're visiting the island, you will never forget the little Coqui with the big sound.
