Corcovado National ParkAbout Corcovado National Park
Corcovado National Park occupies much of the Osa Peninsula on Costa Rica’s southern Pacific coast and is recognised for exceptionally high biodiversity. The park preserves large tracts of lowland rainforest, rivers and coastal habitat and is often visited by those seeking extended wildlife-focused trips.
Trails range from short circuits near ranger stations to multi-day routes into interior forest, where guides and ranger stations such as Sirena are focal points for wildlife observation. Visitors come to search for species like tapirs, peccaries and large assemblages of birds and primates; encounters with elusive predators are possible but rare and require patient field time.
The park was created to protect one of the largest remaining blocks of Pacific lowland rainforest in Costa Rica and has been managed to limit impacts through regulated access and campsite controls. Over time research presence and careful trail management have helped maintain its relatively undisturbed character.
Corcovado sits on the Osa Peninsula in Puntarenas Province; common access routes start from the coastal towns of Puerto Jiménez and Drake Bay, from which boats or small flights reach park entry points.
- Biodiversity highlights: The park is one of the country’s most biodiverse mainland reserves; sightings of tapir and many large bird species are possible but require time and quiet on the trails.
- Access and logistics: Access is remote and commonly requires boat travel or small aircraft; multi-day treks or guided stays at ranger stations are typical for deeper exploration.
What to See#
- Sirena Biological Station: Sirena Biological Station on the park’s interior, a major research and wildlife-viewing hub where trails radiate into primary rainforest.
- Coastal and riverine zones: Coastal rainforest, beaches and lowland river systems that form the park’s shoreline and provide access points for boats and trails.
- Gateway towns and landing sites: Access points such as Puerto Jiménez and Drake Bay that serve as common launching locations for guided trips into the park.

How to Get to Corcovado National Park
Corcovado National Park is on the Osa Peninsula and is accessed via Puerto Jiménez or Drake Bay. Most visitors fly from San José to Puerto Jiménez or Drake Bay on small domestic flights (about 30-60 minutes), or drive to Sierpe and take a boat transfer to park entry points. From Sierpe the boat ride to park access points (and to Sirena station from Drake Bay) can take around 1-3 hours depending on landing and sea conditions; guided transport and park shuttles are common.
Tips for Visiting Corcovado National Park
- Book boats, permits and a local naturalist guide well before arrival - access is by water or limited road routes (Puerto Jiménez or Drake Bay) and logistics fill up, especially in high season.
- Visit in the dry season (roughly December-April) if you prefer firmer trails and easier hiking; if you go in the green season expect muddy trails and fewer day‑visitor crowds but bring appropriate planning.
- Choose entry point based on your plan: Puerto Jiménez gives easier land access to some sectors, Drake Bay is better if you want shorter boat transfers to Sirena; many visitors underestimate travel time between access points.
