After breakfast, take a hike in Selva Verde's private reserve that consists of 500 acres of primary forest. The reserve and the surrounding forests provide habitat for over 300 bird species, 120 species of mammals, 48 amphibian species, 89 reptile species, more than 10,000 species of insects, approximately 1,500 species of orchids and 330 species of trees. In the afternoon, take an exciting whitewater rafting trip on the Rio Sarapiquí. Rapids range from Class I-III. Along the way, you will be able to stop to swim in the river and enjoy some fresh fruit. After dinner, attend a presentation on the Mesoamerican Biological Corridor (MBC). Selva Verde is located in the MBC, which is an international initiative that links critical habitats from southern Mexico and Belize to Panama in an effort to conserve biodiversity and promote sustainable development throughout this ecologically fragile region. This region of Costa Rica's rainforest is important because it is the last remaining area that provides habitat for the endangered Great Green Macaw.
