Costa Rica’s Osa Peninsula lies between the Pacific Ocean and Golfo Dulce in the country’s southwest. One of the most biodiverse regions in the world, it is home to an extraordinary variety of wildlife, from monkeys and tapirs to colourful tropical birds, reptiles and amphibians. Corcovado National Park protects vast tracts of rainforest, wetlands and coastline, offering visitors opportunities to explore its rich ecosystems on guided walks. Along the coast, beaches and surf breaks invite exploration, while the waters around Isla del Caño attract divers and snorkellers with their coral reefs and abundant marine life. Dolphins and whales can also be spotted in the surrounding waters. Puerto Jiménez, the peninsula’s principal town, serves as a convenient base for excursions, with restaurants, shops and accommodation. For a glimpse into the region’s pre-Columbian past, the Finca 6 Archaeological Site features ancient settlement remains and remarkable stone spheres associated with the Diquís culture.
