Only in Monteverde would visitors groove to the nightlife at an exhibition of 24 species of frogs, toads, and other amphibians. Bilingual biologist-guides take you through a 45-minute tour of the terrariums in the Frog Pond of Monteverde (Ranario de Monteverde), just outside Santa Elena. For the best show, come around dusk and stay well into the evening, when the critters become more active and much more vocal. (Your ticket entitles you to a second visit the same day, as well as a guided tour.) The complex has a butterfly garden with 30 different species and an insect museum. There's a small frog-and-toad-and-butterfly theme gift shop.
