Also known as Puerto Viejo de Sarapiqui, it is only a 1.5 hour drive north of San Jose. One route takes you past the dramatically forested mountains of Braulio Carrilo National Park, the other past Poas Volcano and La Paz Waterfalls. Lowland offers exceptional wild and birdlife. World famous La Selva Biological Station is located here.  Monkeys, parrots, toucans, iguanas, caiman, sloths, poison dart frogs and basilisk lizards are regular rainforest residents.. The Sarapiquí River is great for Class III white water rafting upriver and wildlife boat cruises downriver.
