Trail and conditions
The climate is hot, rainy and very humid. Some routes are long, remote and affected by rivers or tides.
Safety and park rules
Never hike alone or improvise crossings. Follow ranger and guide directions; keep away from peccaries, crocodiles, cats and snakes.
On-site signs, staff and official closures always take precedence over this guide.Responsible visit
Do not chase wildlife or leave trails, and carry all waste out. Observation depends on quiet, distance and luck.
How to understand this park
Corcovado is a system of sectors rather than a single entrance. Sirena lies among coast, rivers and forest; San Pedrillo combines primary forest and shore; La Leona, Los Patos, Los Planes and El Tigre differ greatly.
Exceptional biodiversity does not make the park a zoo. Silence, weather, fruit availability and chance shape encounters. The main reason to visit is experiencing remote rainforest under strict rules.
Practical plan

- Drake Bay for marine access to San Pedrillo/Sirena; Puerto Jiménez or Carate for the southeast
- Getting around
- Coordinated boat, 4×4 or hiking access by sector

Questions before booking
Can I arrive without a reservation?
No. SINAC requires advance booking; confirm sector, meals, transport and guide before travelling to Osa.
Is a guide compulsory throughout the park?
Requirements depend on the route. SINAC requires one for crossings such as La Leona–Sirena and Los Patos–Sirena; verify your sector.
Is Sirena an easy outing?
No. Even a boat arrival includes landing, heat, humidity and walking in a remote setting. The station does not remove the need to plan.
