About three quarters of the country's residents live in The Central Valley, and you can see why - Costa Rica's geographical heart is home to San José, coffee plantations, volcanoes, and rapids ideal for rafting. The region has a very pleasant climate, due to its altitude, meaning that days are warm without being sticky, and nights are comfortably cool. It is certainly worth spending additional time exploring this lush area, whether white water rafting down the Pacuare river, visiting the active Poas volcano, or learning about coffee roasting and the cultivation process of macademia nuts.
