Getting Here and About Us

Getting Here:
We are located off route 245, three-minutes drive from downtown Puerto Jimenez. From the main street of PJ, turn right at the BM supermarket going toward Matapalo/Carate. Take the second street on the right (the gym road), go down the little hill  and to the end of the road. Your guide will meet you at the green bench (before the road takes a sharp left) at the sign for Osa Interactive Gardens. We are next to Cacao Monkey Lodge. You can find us on WAZE or ask us about courtesy in-town pick-up for tour clients.

“Our mission is to share butterflies and the tropical rainforest with the next generation.”

Butterfly farm and botanical garden site history

The Osa Peninsula is located in southwestern Costa Rica, in the Puntarenas Province. The Pacific Ocean to the west, the Golfo Dulce to the east and dense lowland jungle in between, the area attracted settlers for its natural resources of gold and timber. The farm property was logged in the early 20th century and was later established as chocolate farm. The project was eventually abandoned due to an unmanaged pathogen in the cacao trees that drastically decreased chocolate production. Once a sick, dark, closed canopy monoculture cacao plantation, the site now has been re-established as a diverse and dynamic jungle supporting hundreds of species. It is at the core a forest restoration experiment and example of the mission of Osa Interactive Gardens.

Osa Interactive Gardens is an Environmental Education Center dedicated to conservation, community, and education.
