The Bioarca resides in 140 acres of primary and secondary rainforest. Access is by trail. Most of the Bioarca is protected by us as a biosphere preserve for prime tapir habitat, while 10% is managed to supply food and habitat for tapirs, tayras and other mammals including ourselves and our guests. 

The Peninsula is considered one of the most bio-diverse places on earth.
