The Osa Peninsula, a secluded nature wonderland, stretches throughout most of Costa Rica's southern Pacific coastline.
To the backdrop of verdant mountains, the tropical rainforests here merge with isolated pristine beaches to form one of the county's most beautiful regions.
The area is one of diverse biological intensity rarely seen in one of the world's tallest rainforests.
As well, the Osa Peninsula embraces the largest expanse of lowland rainforest in Central America.
Corcovado National Park Nearly 80% of the peninsula is protected by Corcovado National Park, where many of the country's rare and endangered animals and birds reside.
Sprawling along the west coast, Corcovado is a Garden of Eden.
The last region of the world's tropical humid forest, the park's myriad species of trees are overhung with bromeliads, orchids and other wild flora.
Cool clear streams meander through the forest to spill into the warm Pacific waters.
This microcosm of bio-diversity houses thousands of species of flora and fauna, where wildlife watching is unmatched - by simply stepping outdoors, you cross paths with various types of monkeys, coatamunds, caiman and ocelots, while endangered scarlet macaws, toucans and 400 other species of birds roam above.
While the desert beaches beckon invitingly, the real attraction of Corcovado is its wildlife and plants.
Drake Bay and Puerto Jimenez, the 2 main gateways into the region, lie on the northern and southern edges of the peninsula.
Puerto Jimenez, the region's largest town, lies on the Golfo Dulce on the peninsula's southernmost tip.
Here calm, isolated beaches encompass one of the most secluded corners of Costa Rica, where adventurers come to experience nature in the raw - lush vegetation, mangrove swamps with abundant mammals and birds, and a trio of unparalleled beaches.
Nestled in the hills above the lush coastline on the peninsula's northern tip, remote Drake Bay is one of Costa Rica's most peaceful destinations.
It offers easy access to Corcovado, as well as nearby Cano Island, a marine life treasure trove.
Here, snorkelers and divers come for the chance to swim with sea turtles, marlins, rainbow fish and dolphins.
Whale and Dolphin Watching The Osa Peninsula is not only appealing for its wildlife and jungle trekking.
This is a region where marine life abounds.
Costa Rica's southern coast is the favorite playground for dolphins and whales.
Five kinds of dolphins and 3 species of whales inhabit the region's coast at Playa Dominical.
Dolphin and whale watching adventures provide an excellent opportunity to see humpback whales lunging out of the ocean, then back-flipping into the waves.
To the backdrop of Drake Bay and the beautiful surrounding beaches, these expeditions take you into the protected waters of the Marina Ballena National Park where whales, dolphins, tropical fish and sea turtles abound.
While some whales inhabit these waters throughout the year, most migrate here from November to March and from July to December, when they give birth to their young.
These temperate Pacific waters, however, are the year-round habitat of dolphins and sea turtles, where adults and children alike will thrill to the opportunity of swimming with these playful creatures.
The remoteness and untouched beauty of the Osa Peninsula make this an adventurer's paradise and a region well worth visiting for its untainted natural beauty and its wildlife and marine life excitement.
