Osa Peninsula

Costa Rica’s Osa Peninsula is wild, remote, and teeming with life. Home to Corcovado National Park, it’s one of the most biologically intense places on Earth. From dense jungles to untouched beaches and crystal-clear waters, this region offers deep nature immersion for true adventurers. The Osa Peninsula harbors incredible wildlife not only on land but also in the sea. It’s one of the best places to watch whales and dolphins and to snorkel near Caño Island.

"Horizontes is top notch This is our second trip with Horizontes and was equally impressed both trips. Everything arranged was on time, top shelf and the best experiences. They were super easy to work with. Just gave them a region and general ideas of what we like to do. They created a plan, worked with us as we tweaked activities a bit and it ended up to be perfect. The boutique hotel and tours were staffed with extremely nice and helpful staff, making everything great. We will definitely use them again!"
