To the northeast of the Central Valley, this region includes a large part of the provinces of Alajuela and Heredia, extending to the north to the border of the province of Guanacaste. The rains and cloudiness are characteristic of this zone throughout the year, nevertheless, from February to April there is a noticeable decline in the amount of precipitation and the number of rainy days.

The whole region portrays an important economic growth due to its agriculture production and the surge of tourism, mainly in Sarapiqu?, San Carlos (famous for the Arenal Volcano), and San Ram?n. Each of these places offers special qualities that differentiate them and put them in a privileged position in the country.
