Corcovado National Park Sirena Station Overnight Tour (2 Days / 1 Night)

Corcovado Sirena Station Overnight Tour: The Ultimate 2-Day Rainforest Immersion

Step deep into the beating heart of Costa Rica’s wilderness with our exclusive 2-Day / 1-Night Sirena Biological Station Overnight Expedition. Located in the remote core of Corcovado National Park—celebrated by National Geographic as “the most biologically intense place on Earth”—Sirena Station offers an intimate wildlife experience found nowhere else in the Americas. While a day tour scratches the surface, staying overnight allows you to experience the jungle during its two most active and magical moments: twilight along the wild Pacific shoreline and the raw awakening of the dawn chorus at 5:00 AM.

Why Experience Corcovado Overnight at Sirena Station?

• Peak Wildlife Activity: Most rainforest species are active at dawn and dusk. Sleeping inside the park gives you privileged access to the trails before day-trippers arrive and long after they leave.
• High Encounter Probability with Baird’s Tapirs: Sirena is the world capital for the endangered Baird’s tapir. Late afternoon walks to the Sirena River mouth and beach provide unmatched opportunities to see tapirs foraging along the sand.
• All 4 Costa Rican Monkey Species: Watch mantled howlers, white-faced capuchins, endangered Central American squirrel monkeys (tití), and agile spider monkeys swinging through the canopy.
• Rare & Iconic Fauna: High encounter chances with white-lipped and collared peccaries, tamandua anteaters, coatis, tayras, spectacled caimans, and elusive big cats monitored via local trail cameras.
• Birdwatcher’s Paradise: Spot scarlet macaws in pairs, king vultures, fiery-billed aracaris, crested curassows, and vibrant trogons.
• Authentic Jungle Sanctuary: Fall asleep to the mesmerizing symphony of frogs, night insects, and the distant roar of the ocean from the sheltered, open-air wooden bunkhouses of Sirena Station.
