andesitic shield complex in centralCosta Rica 22 km north of San José, in the province of Heredia.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 hasn't 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. it is 2906 m above sea level
