This zone is located in the geographic center of Costa Rica, the most populated zone of the country. There is a great variety in altitudes and topographies that allow different micro climates and a very wide biodiversity.
This land has plenty of plains and a mountain system called the Central Volcanic Mountain Range. Towards the north you can find active and inactive volcanoes, such as the Poas in Alajuela, the Barva in Heredia and the Irazu and Turrialba in Cartago.
