Barva Volcano is an inactive volcano. On the Eastern side of the mountain it has a lake in what formerly was the volcanic crater, called "Laguna de Barva", and in the Western side it has three hills on the top which are called "Las Tres Marías". It is an andesitic shield complex in central Costa Rica 22 km north of San José, in Heredia Province. It sits on the small agricultural community of Sacramento.
Barva has a dozen different erruptive spots in the summit and some parasitic cones in the flanks of the mountain. Its three principal summits visible from the Central Valley give it the common local name of Las Tres Marías (The Three Marys)
Four pyroclastic cones are constructed within the 2 x 3 km caldera at the central and NW part of the summit. The SW peak contains four cones, one of which has a crater lake.
The volcano has not presented any erruptive activity since colonial times. Eruptions were reported around 1760 but later visits to the summit did not provide evidence of eruptions during historical time.
