The Osa Peninsula in Costa Rica is often called “the last wild frontier”—and for good reason. Despite covering less than 0.001% of the planet’s surface, the Osa is home to 2.5% of all species on Earth.
Here are just a few incredible facts about this untamed paradise:
Over 700 tree species—more than in all of North America combined.
Four species of monkeys—the only place in Costa Rica where you can see them all in one region.
Over 10,000 insect species, including some found nowhere else.
More than 400 bird species, from scarlet macaws to toucans.
In the nearby Golfo Dulce, humpback whales arrive twice a year to give birth, one of only a few tropical fjords in the world where this happens.
At the heart of the Osa is Corcovado National Park, described by National Geographic as “the most biologically intense place on Earth.” Protecting over 160 square miles of rainforest, it is the crown jewel of Costa Rica’s protected areas.
Imagine waking up here, surrounded by pristine jungle, endless coastlines, and the sound of nature all around you.
With its unmatched biodiversity, peaceful beaches, and growing eco-conscious tourism, the Osa Peninsula is more than just a place to visit—it’s a place to invest in the future.
