Introduction
The Osa Peninsula is Costa Rica’s last great wilderness—a remote, pristine paradise heralded by National Geographic as “the most biologically intense place on Earth.”
Home to Corcovado National Park, the peninsula shelters a staggering diversity of life in an untouched environment. Unlike traditional beach or adventure destinations, the Osa Peninsula offers guests the chance to become part of a living conservation story.
Here, resorts are not merely accommodations—they’re research outposts, ecological sanctuaries, and immersive classrooms that combine responsible luxury with citizen science. This is where nature, science, and adventure converge in one of the planet’s final ecological frontiers.
