Course Locations - Costa Rica

Rancho Mastatal, Costa Rica


At Rancho Mastatal, students live on a small organic farm dedicated to sustainable living practices and education.  You can view a slideshow of ranch life here.  The ranch is located alongside the newly created La Cangrega National Park and is home to a huge diversity of plants and wildlife species.  The small, 100+ person community of Mastatal itself is vibrant, supporting farmers and merchants.  Students will share three wonderful, home-cooked, mostly-vegetarian meals each day, have class in a open-air classroom and practice skills and participate in scenarios in the rainforest along the streams that run through the community and park.  Students arriving early or staying later can participate in other amazing educational opportunities, including world-class solar energy workshops and classes in natural building.


Shared housing, camping and homestays in the community all available. 


Three vegetarian meals each day.  Amazing quality.

What to Bring
