Cocos Island National Park: Nestled in the vast expanse of the Pacific Ocean, some 330 miles (523 km) off the coast of Costa Rica, Cocos Island National Park, also known as Isla de Coco, emerges as an unrivaled gem. This pristine sanctuary, just 5 degrees north of the equator, holds a unique status, perched a few hundred miles north of the illustrious Galapagos Islands. Established in 1978, the park is a resolute guardian of unparalleled ecological diversity, safeguarding the habitats vital to marine wildlife, particularly pelagic species, including awe-inspiring sharks. Its exceptional significance led to UNESCO's World Heritage Site designation in 1997. Governed by the Costa Rican government, this natural haven expanded its protective embrace in 2011 with the establishment of the Seamounts Marine Management Area, a sprawling sanctuary five times the size of the existing park. Cocos Island, a beacon for scuba diving enthusiasts, has earned its place among the world's premier dive destinations, boasting over 20 mesmerizing dive sites encircling its shores.
