Costa Rica
The fact that more than one million tourists visit Costa Rica each year does not happen by chance. The country, located in Central America, is an isthmus where life seems to have created its roots.
Costa Rica is characterized by impressive scenic beauty, a consolidated system of protected areas, social and political stability, high educational levels, and efficient infrastructure and services. All of this offered in a territory of only 51 thousand square kilometers, with scenic Pacific and Atlantic Coastlines, at a distance from each other of only three to four hours by land or 45 minutes by air.
