Corcovado National Park is often described as the “crown jewel” of Costa Rica’s park system. Holding 2.5% of the world’s biodiversity, it is a bucket-list destination for wildlife enthusiasts. While there are several ways to enter the park, Sierpe is the most strategic and scenic starting point.
In this guide, we’ll break down everything you need to know to plan your expedition.

Why Enter Corcovado via Sierpe?
Most travelers choose Sierpe because the journey itself is a tour. Before reaching the ocean, you’ll navigate through the Sierpe River mangroves, giving you an extra chance to spot crocodiles, monkeys, and rare birds before even setting foot in the National Park.
Choosing Your Station: Sirena vs. San Pedrillo
When booking a tour through sierpexplorer.com, you typically have two main options for a one-day tour:
1. Sirena Ranger Station (The Wildlife Hub)
Sirena is world-famous for being the best spot for wildlife viewing. Because it’s located in the heart of the park, animals are less shy.
- Best for: Seeing tapirs, peccaries, and all four species of monkeys.
- The Hike: Mostly flat trails, making it accessible for families and casual hikers.
