In the humid northern lowlands, Sarapiquí is a rainforest and river country built for wildlife and water — whitewater rafting on the Sarapiquí River, boat trips past caimans and river turtles, and biological reserves alive with birds, frogs and monkeys. It’s a working landscape of pineapple, cacao and reforestation projects, and an easy, authentic add-on between the Caribbean and the northern volcanoes.
