Costa Rica UNESCO world heritage sites

Guanacaste province mainland [capital = Liberia]

Conservation Area in Guanacaste National Park @
The enormous variation in environmental conditions favours a high diversity, with two thirds of all species described for Costa Rica occurring within the relatively compact area.

Guanacaste province island [capital = Liberia]

National Park on Cocos Island @
Natural population densities of large top predators indicate a near pristine conservation status of a property that is among the most important sites in the Eastern Tropical Pacific for the protection of large pelagic migratory species, such as the endangered Scalloped Hammerhead Shark and the near-threatened Silky Shark and Galapagos Shark.

Puntarenas province [capital = Puntarenas]

Stone Spheres of the Diquis in Palmar at Finca 6 + El Silencio + Finca Batambal + Grijalba
Special objects of wonder and admiration are the distinctive Diquis stone spheres, which are rare in their perfection of large-sized (up to 2.57m diameter) spherical structures but are also distinct for their number and location in their original positions within residential areas.

La Amistad National Park in Buenos Aeres (also part of San Jose, Cartago and Limon Provinces) @
The scenic mountains and foothills contain impressive footprints of Quaternary glaciation, such as glacial cirques, lakes and valleys shaped by glaciers, phenomena not found elsewhere in the region. The property is a large and mostly intact part of the land-bridge where the faunas and floras of North and South America have met.
