Few places on Earth are as wild, as rich, and as spectacular as Costa Rica’s Corcovado National Park. It’s secluded in the country’s far southwest, on the Osa Peninsula.

Only the truly devoted will reach this incredibly isolated park. Their reward is an oasis of incredible sights—pristine beaches, primary rainforest, waterfalls and rivers—and sightings, including humpback whales, nesting sea turtles, and an array of endangered animals, including jaguars, Central American squirrel monkeys, and Baird’s tapir.
