Santa Rosa National Park was the first national park established in Costa Rica, created in 1971.

Santa Rosa was originally a farm located in the north-western Guanacaste Province, in Costa Rica. Today an old hacienda building, “La Casona,” functions as the monument commemorating the fallen heroes of the different battles that took place here.

Santa Rosa National Park was also created to protect the natural environment beyond the historical site.
