Costa Rica is located on the Central American isthmus, 10° north of the equator and 84° west of the Prime Meridian. It borders both the Caribbean Sea (to the east) and the North Pacific Ocean (to the west), with a total of 1,290km of coastline (212km on the Caribbean coast and 1016km on the Pacific).
Costa Rica also borders Nicaragua to the north (309km of border) and Panama to the south-southeast (639km of border). In total, Costa Rica comprises 51,100 km,² of which 50,660 km² is land and 440 km² is water, making it slightly smaller than the U.S. state of West Virginia.
The nation's terrain is coastal plain separated by rugged mountains in the center of the country. Costa Rica claims an exclusive economic zone of 200 nautical miles and a territorial sea of 12 nautical miles. The country has a tropical and subtropical climate and is part of the Neotropic ecozone. It is part of many ecoregions, including Costa Rican seasonal moist forests, Bocas del Toro-San Bastimentos Island-San Blas mangroves, Mosquitia-Nicaraguan Caribbean Coast mangroves, Southern Dry Pacific Coast mangroves, Central American dry forests, and Talamancan montane forests.
The country is noted for its national park system, administered by SINAC (Sistema Nacional de Areas de Conservacion, or "National System of Conservation Areas"). This agency oversees over 160 protected areas in Costa Rica, of which 26 are national parks. Together these protected areas comprise over one-forth of Costa Rican territory. The largest national park is Cocos Island (Spanish: Isla del Coco), an island about 500km from the Costa Rica's Pacific coast and 24km² in area.
Costa Rica's dry season is from December to April, while the rainy season is from May to November. The highlands areas are cooler. The lowest elevation level in the country is the Pacific Ocean at sea level, the highest point is Cerro Chirripo, a volcanic mountain with an elevation of 3,810m (part of Cerro Chirripo National Park). On a clear day, it is possible to sea both the Caribbean and the Pacific from the peak.
Costa Rica is party to many environmental treaties, including the Convention on Biological Diversity, the Convention on Environmental Modification, the United Nations Framework Convention on Climate Change, the Montreal Protocol, the Ramsar Convention, the International Convention for the Regulation of Whaling, the Desertification Convention, the Endangered Species Convention, the Basel Convention, the Convention on the Law of the Sea, the Convention on Marine Dumping, the Comprehensive Test Ban Treaty.
