Corcovado National Park: One-Day Wildlife Expedition from Sierpe
A full-day expedition from Sierpe into Corcovado’s lowland rainforest and coastline: river boat through mangroves, ocean crossings with dolphin and whale potential, and guided trails at the Sirena/ranger station for close wildlife encounters.
The Experience
Before You Go
Hydrate and carry extra water
Bring at least 2–3 liters in insulated bottles; refills are limited at the ranger station between hikes.
Wear closed, grippy shoes
Trails are muddy with exposed roots; waterproof hiking shoes with good traction reduce slips and blisters.
Use insect repellent and a head net
Expect persistent mosquitoes in humid forests — treat clothing and reapply repellent after ocean crossings.
Protect electronics and documents
Pack cameras and passports in waterproof cases or dry bags for boat sections and sudden rain.

Conservation Note
Access is regulated by park rangers and limited group sizes to reduce impact; visitors should stick to trails and avoid feeding wildlife to support ongoing conservation.
The Osa Peninsula’s landforms are the result of tectonic uplift and marine deposition; human history ranges from indigenous use to 20th-century ranching replaced by park protection in 1975.
