Volcan Barva (2906 meters above sea level) is located in the province of Heredia, very near San Jose. Barva has not erupted in thousands of years, which is why its craters are densely forested. Barva forms part of the Braulio Carrillo National Park and is one of the three volcanic structures known as “Las Tres Marías”. This volcano marks the continental divide of waters, towards one side water flows to the Pacific and the other side to the Caribbean, this characteristic along with its high altitude creates many clouds which gives the name of cloud forest to all the biodiversity in the area.
