Formerly known as the Ranario, or Frog Pond, this place has recently added a butterfly garden and canopy tour – hence, it's now a theme park. The frogs are still the highlight: about 25 species reside in transparent enclosures lining the winding indoor jungle paths. Sharp-eyed guides lead informative tours in English or Spanish, pointing out frogs, eggs and tadpoles with flashlights. Your ticket entitles you to two visits, so come back in the evening to see the nocturnal species. Combined tickets are available.
