Run by the National Biodiversity Institute (Instituto Nacional de Biodiversidad, or INBio), this place is part museum, part educational center, and part nature park. In addition to watching a 15-minute informational video, visitors can tour two large pavilions explaining Costa Rica’s biodiversity and natural wonders, and hike on trails that re-create the ecosystems of a tropical rainforest, dry forest, and premontane forest. A 2-hour guided hike is included in the entrance fee, and self-guided-tour booklets are also available. There’s a good-size butterfly garden, as well as a Plexiglas viewing window into the small lagoon. One of my favorite attractions is the series of wonderful animal sculptures donated by one of Costa Rica’s premiere artists, José Sancho. A simple cafeteria-style restaurant is on-site for lunch, as well as a coffee shop and gift shop. You can easily spend 2 to 3 hours here.
