Located on the Osa Peninsula, Corcovado National Park, a nearly-105,000-acre lowland rainforest, is another of my family’s favorites. The flocks of scarlet macaws — bold red and brilliantly feathered — make Corcovado special. The park is home to one of Costa Rica’s largest populations of these majestic birds.

We explored this difficult-to-reach park as a port stop on an eco-adventure cruise. However, if you don’t arrive by boat, Corcovado is difficult to access. By land, most visitors take a four-wheel drive vehicle from Puerto Jimenez. If not on an eco-cruise, consider booking at an eco-lodge and taking their guided hikes.
