Santa Rosa National Park, National park in Guanacaste Province, Costa Rica

Santa Rosa National Park covers about 495 square kilometres of Guanacaste Province, from the Interamerican Highway to the Pacific coast. Its ten habitats include savannas, deciduous forest, marshlands and mangroves. La Casona, the old hacienda building, stands on the site of the 1856 battle.

The site played a key role in Costa Rican history when forces stationed there repelled a foreign invasion. This 1856 event remains central to understanding the nation's past and independence.

The museum at La Casona displays household items and objects from 19th-century hacienda life, showing how people lived and worked in this region. Walking through these rooms offers a window into the daily routines and customs of that era.

The park is open during daytime hours and offers activities such as hiking, camping, and surfing. Visitors should arrive early and prepare for varying trail conditions, as some paths are more challenging than others.

La Casona, the old hacienda at the park's heart, is a national monument where the 1856 Battle of Santa Rosa was decided in 14 minutes; the building now holds displays on the fallen and on hacienda life. The park also protects two Ramsar wetlands, Laguna Respringue and Manglar de Potrero Grande.
