Barva Volcano
Heredia
Barva Volcano is a complex andesitic stratovolcano located in central Costa Rica's Heredia Province, approximately 22 km north of San José. It features multiple eruptive centers at its summit and numerous parasitic cones on its flanks, forming a dramatic volcanic landscape. The volcano's eastern crater hosts the scenic Laguna de Barva, a crater lake that adds to the area's natural beauty. On the western side, three prominent summits known locally as Las Tres Marías (The Three Marys) dominate the skyline and are visible from the Central Valley. The summit area includes a 2 × 3 km caldera containing four pyroclastic cones, with the southwestern peak having four cones, one featuring a crater lake. Although there were historical reports of eruptions in the 1760s and 1867, geological investigations have not confirmed these events. The last confirmed eruption occurred about 8,050 years ago. The volcano is situated near the small agricultural community of Sacramento and is a notable natural feature in the region, attracting visitors interested in hiking, nature, and volcanic geology.
