Sirena Overnight

Are you ready for the ultimate wildlife adventure in Costa Rica? Look no further than the Sirena Overnight Tour! This tour offers the best opportunity to observe the incredible biodiversity of Costa Rica, right in the heart of Corcovado National Park, often referred to as the most biologically intense place on Earth.

On this two-day immersive experience, you’ll sleep at the Sirena Ranger Station, surrounded by pristine rainforest. Your adventure is fully guided by an ICT certified bilingual guide who will help you uncover the secrets of the rainforest, from the smallest insects to majestic wildlife like tapirs, sloths, monkeys and a lot more.

About Sirena Ranger Station

Sirena is the most remote and wildlife-rich ranger station in all of Corcovado National Park, located deep in the heart of the Osa Peninsula. Accessible only by boat or on foot, it sits at the confluence of the Río Sirena and the Pacific Ocean — a convergence that draws an extraordinary concentration of animals. Scientists and researchers from around the world visit Sirena to study its unique ecosystems, which include lowland primary rainforest, mangroves, rivers, and Pacific beach all within walking distance. Spending the night here is a rare privilege that very few visitors to Costa Rica ever experience.

Wildlife You May Encounter

Corcovado is home to an astonishing variety of wildlife, and Sirena is the best place in the park to encounter them. During your guided hikes you may spot: Baird’s tapir (the largest land mammal in Central America, frequently seen at Sirena), all four species of Costa Rican monkeys — howler, white-faced capuchin, spider, and squirrel monkey — two-toed and three-toed sloths resting high in the canopy, scarlet macaws flying overhead in pairs and large flocks, American crocodiles in the river mouth near the ranger station, bull sharks and dolphins visible from the beach and boat, jaguars and pumas (tracks and sightings are not uncommon at Sirena), giant anteaters, white-lipped peccaries, and agoutis on the forest floor, and hundreds of bird species including toucans, trogons, hummingbirds, and raptors.
