Corcovado National Park closes its Sirena sector from 1 to 31 October 2026, changing access for visitors planning a stay near Puerto Jimenez in Costa Rica. The closure covers day visits and overnight stays at Sirena, while other sectors remain available under the current arrangement.
The park is known locally as Parque Nacional Corcovado, and its October access plan is the result of a seasonal closure combined with maintenance work. For travellers from Western Europe, the practical distinction is important: the national park is not closed in full, but Sirena cannot be used during the stated period.
Sirena closure changes Corcovado visits in October 2026
The Sirena sector is closed to tourists from 1 October through 31 October 2026. The closure includes visits to the biological station and overnight stays, so an itinerary built around Sirena needs a different sector or a different travel period. October closure details identify maintenance and heavy rains as the reasons for the restriction.
The decision was reported by Teletica on 18 September 2026, citing information from Costa Rica’s National System of Conservation Areas, known as SINAC. That report says the Sirena sector remains closed to tourists during October even after its authorised visitor capacity was restored for the period when the sector is operating. Teletica’s access report also identifies San Pedrillo and La Leona as the sectors available to tourists during October.
Corcovado National Park links the closure to Sirena station
Corcovado National Park lies on the Osa Peninsula in southwestern Costa Rica, in Puntarenas Province. SINAC describes six sectors: San Pedrillo, Sirena, La Leona, Los Patos, Los Planes and El Tigre. Sirena is therefore one part of a larger protected area rather than a separate destination, which explains why October access is restricted without stopping every park visit.
The park was created by executive decree in 1975 and later expanded. Its protected landscape includes forest, beaches, coral reefs, mangroves and freshwater marshes. These varied environments connect the access question to the October closure: the route available to a visitor depends on the named sector, not simply on whether the national park appears open. SINAC park information places the area on the Osa Peninsula and records its protected-area history.
Visiting Corcovado National Park: October access from Europe
- Sirena is closed from 1 October to 31 October 2026, including day visits and overnight stays at the biological station.
- San Pedrillo and La Leona are the visitor sectors identified as open during October 2026, so a Sirena plan does not automatically apply elsewhere.
- The park is on the Osa Peninsula in Costa Rica, with Puerto Jimenez serving as the relevant regional reference for travellers planning access.
- The protected area contains forest, beaches, coral reefs, mangroves and freshwater marshes, so routes involve natural terrain rather than an urban attraction.
- Entry requirements depend on your nationality; UK travellers can check the FCDO travel advice at gov.uk/foreign-travel-advice, Irish travellers the Department of Foreign Affairs at ireland.ie.
Travellers should match the permit, guide and transport arrangements to the sector named in the itinerary. The October 2026 closure applies to Sirena, not to every access point recorded for the park.
