Experience Highlights

103,290 acres (41,800 ha) of natural beauty await you at Costa Rica's Corcovado National Park. Spend your days (and one glorious night) where scientists and researchers camp out when they're exploring the incredible biodiversity of Costa Rica. Sirena Biological Station is less than half a mile (800 m) from sandy beaches, and offers you rustic yet charming accommodations in the midst of an incredible tropical forest.

After an early morning boat ride across Drake Bay, you'll settle in at Sirena Biological Station before beginning the first of many hikes. Throughout your time on the island, you'll have the opportunity to see:

  • 500 species of trees
  • 6,000 species of insects
  • 220 species of butterflies
  • nearly 400 species of birds
  • 140 species of mammals
  • 116 species of amphibians and reptiles
  • 4 species of turtles
  • 40 species of fish

and the complex freswater and saltwater ecosystems that house them all. Specific wildlife that you can look forward to seeing include giant ant eaters, poison dart frogs, crocodiles, Olive Ridley turtles, and sloths.

Your accommodations are humble, as your itinerary is meant to have you up and about exploring the natural world. Get ready for some old-school fun as you sleep on a bunk bed. Whisper with your travel mates about all of the amazing things you've seen on day one before falling asleep to the nighttime song of the jungle. Mosquito nets and bed linens are included, so you needn't worry about bringing a bunch of gear. Despite the rugged environment, you'll still have access to clean bathrooms and a brisk shower (the station is not equipped with hot water).
