The South Pacific Region of Costa Rica

Encompassing the largest stretch of prehistoric rainforest on the Pacific coast of Central America, the Osa Peninsula (Península de Osa) is regarded as one of the most biologically diverse and beautiful locations on the planet. The high humidity and rain attributed to its geographic position keep this scarcely populated area flourishing year round as it receives almost 200 inches (508 cm) of rainfall per year. Get ready to explore some wet and humid terrain! Inaccessibility caused by the lack of entry points is enough to keep Costa Rica’s jewel less visited than other destinations in the country. With miles of uninhabited white sandy beaches, Costa Rica's southern region is one of the most stunning and talked about. Friendly people, amazing flora and fauna and lush forests full of activity make up Costa Rica's South Pacific.

Traveling through the region allows you to view the abundance of mangroves and estuaries along the coastline. As much of the area is covered in densely lush rainforest, some of the best wildlife viewing imaginable can be found here. The wealth of rivers in the region, many excellent for white-water rafting, supply the area with amazing biodiversity. The valleys were once the home of thriving banana plantations, but now, the industry has receded, leaving behind evidence of the once booming crop. The endless amounts of eye-catching views along the coast and captivating sunsets ensure for an insurmountable experience.

The base of this region lies along the Pan-American Highway, making that the primary route by car or bus. You can also reach the South Pacific by traveling along Highway 34, which runs along the scenic Pacific coast. To the north of the Osa Peninsula is the important city of Palmar Norte—another main hub in southern Costa Rica and a good 6 hours by vehicle from San José. Adjacent to Palmar Norte is where you will find Palmar Sur, which has a tiny domestic airstrip receiving flights daily from San José. Before you book the 45 minute flight, it is important to know that many of the main destinations on and around the Osa Peninsula have their own Airports, making travel faster and more convenient, but also more expensive. Southeast of Palmar Norte is the village of Chacarita, from which, there is the single road (245) that winds its way around the Dulce Gulf (Golfo Dulce) ending in the small isolated town of Carate, which borders Corcovado National Park to the south. Here you will find endless white-sandy Beaches in both directions. Just beyond Carate seems to be the end of civilization, get ready for a taste of the final frontier!

This region also contains the isolated Coco Island (Isla del Coco), located 300 mi (480 km) offshore to the southwest. The remote island has been declared a national park, as it harbors Coco Island National Park (Parque Nacional Isla del Coco), almost 9 mi² (24 km²) of pristine natural wilderness. The park's studies are dedicated the evolution of the local plant, animal and insect species, many of which are endemic to the region. Excursions can be taken to the island from the various launching points located on the Osa by either boat or plane. Coco Island is perfect for scuba divers who often marvel over the manta rays, whale sharks and hammerheads that like to frequent the beautiful waters around the island.
