Water Bodies of Costa Rica

Costa Rica's natural landscape includes many lakes, lagoons, rivers, and waterfalls. Most rivers that crisscross the country originate in the central volcanic mountains. Gulfs and bays pocket the coasts, while lakes and lagoons dot the countryside and fill mountaintop craters.

The following is a partial listing of the notable bodies of water in Costa Rica.

Gulfs and Bays

• Coronado Bay: Coronado Bay is a bay of the Pacific Ocean on the southwestern coast of Costa Rica, which lies north of the Osa Peninsula.

• Culebra Bay: With its snake-like shape, Culebra Bay attracts many international and national tourists. In addition, this natural area within northwestern Costa Rica's Gulf of Papagayo is marketed as a biological model due to the preservation of its natural environment and the wide variety of species inhabiting this region.

• Golfo Dulce: Golfo Dulce lies between the Osa Peninsula and the southern Pacific Coast of Costa Rica. It takes its name from the large amount of freshwater that flows into it from four rivers whose mouths harbor large areas of protected mangroves.

• Gulf of Nicoya: The Gulf of Nicoya is an inlet that indents the west-central part of the Pacific coast of Costa Rica. The Gulf separates the Nicoya Peninsula from the mainland of Costa Rica.

• Gulf of Papagayo: The Gulf of Papagayo is a large body of water off Guanacaste province and the northwestern coast of Costa Rica. The Gulf and its coastline are part of a significant tourism project by Costa Rica's government.
