Go green on your next getaway! Rancho Margot in El Castillo, Costa Rica, is an ideal example of eco-tourism. In the shadow of Arenal volcano lies this 400 acre sustainable ranch which grows well over half of all the food consumed by their workers, residents and guests. Electricity is generated onsite with two hydroelectric generators, and three on-site bio-digesters produce the methane gas used for cooking and heating in the kitchen. The natural swimming pools are heated with excess energy, and all roofs are living, incorporating local flora to help control the temperature inside. Truly live the pura vida at the sustainable and self sufficient, Rancho Margot.
