Der Miravalles ist ein 2028 m hoher Stratovulkan im Nordwesten Costa Ricas. Er liegt in der Provinz Guanacaste in der Nähe des Rincón de la Vieja.
Der Krater entstand vor etwa 0,6 bis 1,5 Mio. Jahren durch mehrere explosionsartige Ausbrüche. Die einzige von Menschen beobachtete Eruption war eine kleine Gas-Explosion an der Südwestflanke des Vulkans im Jahre 1946.

Miravalles volcano.jpg
Miravalles volcano rises above a thermal area on its SW flank. The 2028-m-high andesitic stratovolcano is one of five post-caldera cones constructed along a NE-trending line within the Pleistocene 15 x 20 km Miravalles caldera. Morphologically youthful lava flows cover the western and SW flanks of the volcano. The only reported historical eruptive activity was a small steam explosion in 1946, although high heat flow remains, and a producing geothermal field is located within the caldera.
