The Osa Peninsula, nestled along Costa Rica’s Southern Pacific Coast, is a prime rainforest spot recognized by National Geographic for its unparalleled biodiversity.

This pristine expanse borders Drake Bay to the northwest, the Pacific Ocean to the west, and the Golfo Dulce to the east. Unspoiled landscapes, secluded shores, and wildlife thrive here amidst lush primary rainforests and diverse freshwater and marine ecosystems.

Drake Bay by the Pacific Ocean

Perched on the western edge of the Osa Peninsula and reachable by boat or a small airstrip, Drake Bay is the gateway to two prominent attractions: Corcovado National Park and Caño Island Biological Reserve.

These destinations promise adventurous travelers an authentic encounter with nature. Venture along forest trails, discover waterfalls, meander beside spring-fed rivers, and explore tide pools. Indulge in some of Costa Rica’s finest snorkeling and scuba diving experiences, all while residing in a top-notch jungle lodge enveloped by rainforest tranquility.

Corcovado National Park

Corcovado National Park, situated on the western flank of the Osa Peninsula, is its primary natural gem. Renowned for its unparalleled richness and diversity, it’s hailed as one of the most vibrant tropical areas globally.

Encompassing nearly half of the peninsula’s expanse, this park boasts Central America’s most extensive lowland rainforest. Here, you’ll encounter abundant wildlife, including a substantial population of scarlet macaws—second only to Carara National Park—and all four species of monkeys and sloth varieties.

Among the more elusive inhabitants are endangered jaguars and pumas. Since 2014, park regulations have mandated that visitors be accompanied by a guide, a measure aimed at preserving the park’s ecological integrity.

Many lodges in the region offer day tours to this natural wonder, ensuring visitors can easily and insightfully experience its magnificence.

The Cano Island Biological Reserve

Cano Island Biological Reserve – accessible from Drake Bay

Twelve miles offshore of Drake Bay is Cano Island, home of Cano Island Biological Reserve. The island was once used as a cemetery in pre-Columbian times and is where many of the mysterious stone spheres of Central America are located, thought to have been carved by pre-Columbian natives by scientists.

Today, Cano Island is especially popular for diving and snorkeling.
