Costa Rica is a country bursting with natural wonders, from active volcanoes to rainforest-blanketed mountains to dreamy cloud forest reserves and beautiful white-sand beaches. Lush forests are astoundingly rich with living creatures -- visitors are quite likely to spot monkeys, iguanas, sloths, parrots, and toucans. Wildlife lovers and travelers interested in sustainable organic farming might especially love staying at one of Costa Rica's many working farm hotels. Throughout Oyster's extensive travels across Costa Rica (we've visited 500 hotels and counting), we've stayed at a number of hotels with working farms. Here are our favorites, from a secluded farm hotel in the middle of the rainforest to a century-old historic cattle ranch at the foot of the Rincon de la Vieja volcano.
