Marino Ballena National Park
Encompassing 270 acres of land (110 terrestrial hectares) and 13,300 acres of ocean (5,400 marine hectares) is the Marino Ballena National Park (Parque Nacional Marino Ballena). Positioned just 10 mi (16 km) south of Dominical and 112 mi (180 km) southwest of San Jose, Marino Ballena is one of the newest national parks in Costa Rica. Established in 1990, the park contains the largest coral reef on the Pacific side of Central America. The park&s waters are also great vantage points for viewing the humpback whale as it migrates (Dec. to April) from as far away as Alaska and Hawaii down to Cano Island, just off of the Osa Peninsula.
