Guanacaste is a province of Costa Rica. It is located in the northwest part of the country. Guanacaste gets its name from the guanacaste tree – or the ear pod tree – which is the national tree of Costa Rica.

Guanacaste is home to about 264,000 people living in an area of 3,915 square miles. It is about the same size as the state of Connecticut, but Connecticut has a population of 3.5 million people.
