More than just a butterfly conservatory (although it has one of the largest butterfly exhibitions in Costa Rica). Altogether there are six domed habitats (recreating the butterflies' natural Costa Rican ambiance), a ranarium, an insect museum, a medicinal herb garden, and an hour’s worth of trails through a botanic garden and along the river. The birding is also excellent here, and there are wonderful volcano views. The conservatory is located on the main road uphill from the lake.
