Corcovado Ranger Stations Compared: Sirena, San Pedrillo, La Leona, Los Patos

Here is how the four sectors, plus the short Los Planes trail, stack up on access, trails and who each one suits.

Every one of these five entry points charges the same $16.95 non-resident adult entrance fee and runs 7:00 am to 3:00 pm daily, so the differentiator between them is genuinely the terrain and the trail network, not the price at the gate. The full fee breakdown, including the child and resident rates, sits on the entrance fee page.

Sirena is the park's flagship station, and its trail network is the largest of the four: eight trails covering about 20 km. Sendero Ollas runs 3 km through primary forest and takes about five hours round trip, a route known for birdlife. Sendero Corcovado is a shorter 1 km loop, about two hours.

Sendero Río Claro is 3.5 km and flat, reaching the Río Claro and the beach. Sendero Los Naranjos starts beside the Sirena airstrip and runs 3 km, mostly through secondary forest, ending at the beach.

• Eight trails, about 20 km total across the Sirena network
• Sendero Ollas: 3 km, about five hours, primary forest
• Sendero Río Claro: 3.5 km, flat, reaches the river and the beach
• Sendero Los Naranjos: 3 km, beside the airstrip, mostly secondary forest

One safety point that should never be softened: at the mouth of the Río Sirena, SINAC's own signage states that bull sharks and crocodiles can be seen at high tide, the park authority's own wording, not a rumor. Sirena also closes for the whole of October, for maintenance and because it is the rainiest month of the year, so October is off the table for this sector regardless of how the visitor caps are set that season. Overnight visitors book a separate lodging and meal concession, covered on the entrance fee page, and the fuller station profile lives at the Sirena station guide.

San Pedrillo is the easiest sector to reach on a single-day trip, a 30 to 45 minute boat ride from Drake Bay, the shortest crossing of any station. The overland alternative is a walk of about 10 km along the beach, passable only at low tide, so most day visitors take the boat rather than time a coastal walk against the tide table.

• Boat from Drake Bay: 30 to 45 minutes each way
• Overland beach route: about 10 km, low tide only
• Known for a waterfall trail and a forest circuit close to the station
• Realistic pick for a single, self-contained day without an overnight component

Because the crossing is short and the trails sit close to the station, San Pedrillo suits travelers who want a full Corcovado day without committing to the longer boat or overland routes into Sirena. A separate profile of the sector, including the waterfall and its trail conditions, is at the San Pedrillo guide.

La Leona is entered from the community of Carate, reached by 4x4, shared taxi or small plane from Puerto Jiménez. From Carate, the entrance itself is a 3.5 km walk along the beach. From La Leona onward toward Sirena, the route runs about 16 km and takes roughly six to seven hours along beach and forest, rated by SINAC as moderate intensity.

• Carate to La Leona entrance: 3.5 km along the beach
• La Leona to Sirena: about 16 km, six to seven hours
• SINAC rates the trail intensity as moderate
• The Río Claro crossing along this route depends on tide timing, not something to guess at

The Río Claro crossing further along this route is the point where tide knowledge genuinely matters, which is the exact hazard covered in full on the do you need a guide page; this is not a route to attempt without someone who reads the tide table before you set out.

Reduced to the two numbers that matter most when you're actually planning a day, approach time and difficulty, the four walking and boating routes look like this.

The boat routes into Sirena and San Pedrillo are the two genuinely easy ways in; everything on foot demands either a full day of walking or, at Los Patos, repeated river crossings that rule out a casual approach. Whichever route you're weighing, the do you need a guide page covers why none of these routes are attempted solo in the first place.

Los Patos

Los Patos is land access only, reached via the community of Guadalupe. It is passable by 4x4 in the dry season and only by tractor in the rainy season, and the route crosses the Río Rincón about twenty times on the way toward Sirena. This is the sector with the fewest shortcuts; the crossings are frequent enough that it is not a route to treat as a casual walk, particularly outside the dry months.

• Land access only, via Guadalupe
• 4x4 in the dry season, tractor only in the rainy season
• Crosses the Río Rincón about twenty times en route

Los Planes

Los Planes is the outlier of the group: a single flat trail of 4.2 km, suitable for all visitors, and a strong pick for birdwatching. SINAC names the sector as puma habitat, the emblematic species associated with Los Planes, though sightings of any puma anywhere in the park remain uncommon and unpredictable rather than something a visitor should expect on a given day.

• Single flat trail, 4.2 km
• Suitable for all fitness levels
• SINAC's own emblematic species for this sector: the puma, rarely seen
