Often referred to as the “most biologically intense place on Earth” by organizations like the WWF and National Geographic, Corcovado National Park is one of the most pristine nature destinations on the planet. The place that represents less than 0.001% of the globe’s surface, but contains roughly 2.5% of the world’s biodiversity.
Corcovado National Park is one of the most remote parks in the country. Visiting this raw and wild area can be challenging, requiring visitors to arrive by boat or fly in. But no matter how you arrive, visitors must travel with a local guide, not only for your own safety but also because it is the best way to enjoy and discover all the treasures the park possesses.
Day tours inside the park are the easiest and one of the best ways to explore for families with young children (although children under 10 years old might want to skip the trip for now). Couples and small groups often spend a day exploring the park, but if you’re up for a deeper experience, consider an overnight stay—either camping or staying at one of the rustic ranger stations inside the park.
To reach Corcovado National Park, you’ll need to stay in either Drake Bay or Puerto Jiménez, located on opposite sides of the Osa Peninsula in southwestern Costa Rica. Accommodations are plentiful in both areas, and there’s something for every budget, ranging from simple options to a handful of luxury eco-lodges surrounded by the wild fauna and flora of Osa.
Our Remote Adventure, Avid Explorer, and Romantic Adventure itineraries can all include time in and around Corcovado.
Sunset on Drake Bay in Corcovado, Costa RicaCorcovado National Park: Corcovado’s Biodiversity Extravaganza
Corcovado National Park is home to one of the few remaining original patches of lowland rainforest in Central America. Thousands of years ago, when North and South America joined and Central America emerged from the ocean to complete the bridge, fauna and flora from both North and South met in Costa Rica’s territory, creating the rich biodiversity today. Miraculously, Corcovado has been able to preserve it almost untouched.
Hiking the trails of Corcovado, you’re surrounded by exotic wildlife at every turn. You might see all four species of Costa Rican monkeys moving through the trees, or catch a quiet glimpse of a jaguar or puma—two of the five wild cat species that live in the park. Baird’s tapirs are often spotted resting in muddy pools or wading in coastal shallows. In the rivers, bull sharks and American crocodiles occasionally cross paths as they hunt. Owls stay tucked away from the sun but sometimes peek out as you pass. And if you’re fortunate, you might look up and see a harpy eagle perched high in the canopy.
Close to 400 species of birds call the park home (half of the entire bird list of Costa Rica!), including the biggest population of scarlet macaws in the country. There are more than 120 species of mammals inside the park. Some mammals include various species of bats, rodents, and anteaters. The rivers and lagoons host 40 species of freshwater fish. More than 8,000 species of insects scurry around the forest floor and in the trees. Additionally, there are 40 species of amphibians and 70 species of reptiles. Just offshore, four kinds of sea turtles come to nest on the park’s beaches.
Giant trees populate every corner of the park. There have been more than 600 species identified, which is over 25% of the entire species of trees found in Costa Rica! Lastly, 13 major ecosystems inside the park include lowland tropical rainforest, mangrove swamps, highland cloud forest, coastal marine, beach habitats, and palm forest.
Getting to Know Corcovado National Park’s History
Located on the outer edge of the Osa Peninsula on Costa Rica’s southern Pacific Coast, Corcovado National Park covers roughly 40% of the peninsula—around 450 square kilometers (or 175 square miles).
Pre-1960s – A Region Once Overlooked
Until the 1960s, this region was largely overlooked. Then, loggers turned their eyes toward the untouched forest filled with giant trees and turned it into a profitable commercial logging business. For the next 15 years, the forest was exploited for its valuable natural resources.
In October 1975, as part of a nationwide effort to reverse deforestation, the government declared Corcovado a National Park. The designation brought a halt to large-scale logging and protected the park’s biodiversity and wildlife.
1980s – The Gold Rush and Park Expansion
In the early 1980s, gold was discovered near the northern edge of the park, drawing thousands of artisanal miners and their families to the area. To prevent commercial mining, the government expanded the park’s territory in 1985 to include the mountainous regions where gold had been found.
The artisanal miners were evicted, and their trade was officially banned.
Recent Times – A Shift Toward Conservation and Ecotourism
For many years, Corcovado was a source of social unrest, as miners and loggers claimed they were robbed of their land. Still, after years of legal battles that ended in cash settlements, a broader awareness took hold. The value of protecting nature—and the realization that tourism offers a more sustainable way to make a living—ultimately prevailed.
Despite its status and protections, the park remains vulnerable to small-scale mining, poaching, and hunting. To help safeguard the area, Corcovado is supported by four ranger stations that serve as hubs for park patrols and entry points for visitors.
Today, Corcovado stands as a symbol of national pride, not only for its unmatched biodiversity but also for the country’s commitment to environmental preservation.

Sirena Ranger Station: The Heart of Corcovado
Sirena Ranger Station, the most famous and remote of the four, is located on the coast in the center of the park. It is the most popular destination for one-day or overnight visitors.
Because of its remote location, it can only be reached by boat or small aircraft from Puerto Jimenez or Drake Bay. Sirena is also a base for many researchers conducting studies within the park.
San Pedrillo Ranger Station is located along the northwest coast of the park. Most visitors reach it by boat from Drake Bay or Uvita, with Drake Bay being just 20 minutes away.
This entrance is well-suited for short hikes and day trips.
Los Patos Ranger Station: Inland Wilderness Gateway
Los Patos Ranger Station is located inland on the northern side of the park. Reaching it can be a challenge due to the lack of roads. Visitors either hike in or hire a 4×4 taxi from the nearby town of La Palma.
Because the route involves crossing multiple rivers, this service is only available during certain times of the year when water levels are safe.
La Leona Ranger Station: A Popular Starting Point
La Leona Ranger Station is located on the southwest end of the park along the coast and is one of the most common entry points. To reach it, visitors hike 3.5 kilometers (just over 2 miles) from the town of Carate.
This entrance is the starting point for the popular La Leona to Sirena coastal trail.
What to Expect at Corcovado’s Ranger Stations
All four ranger stations provide visitors with basic amenities, including toilets, showers, potable water, pay phones, designated camping areas, and hiking trail access.
At Sirena Station, visitors can stay in very simple shared accommodations—basic rooms with three bunk beds—and have the option to pre-order meals, which are served on a strict schedule in a communal dining area.
Hiking in Corcovado National Park: Your Guide to Incredible Hikes
Hiking to Sirena Station
When hiking into Sirena Station, you have several options, including the trail from La Leona Ranger Station to Sirena (19.5 km / 12 miles) or Los Patos Ranger Station to Sirena, known as the Río Pavo Trail (25 km / 15 miles).
La Leona Trail: Coastal Access to Sirena
The hike from La Leona to the park is roughly 16 km (10 miles) long, plus an additional 3.5 km (2 miles) on the beach to/from Carate. Many hikers prefer this trail as their way in and out of the park. The route follows the coastline, alternating between coastal forest and several deserted beaches. You’ll need to cross a river very close to Sirena Ranger Station, so a change of shoes is a must.
Río Pavo Trail: Through the Heart of Corcovado
The trail from Los Patos takes you through the heart of the park. It can be hiked in either direction, but heading south means a downhill hike for the first 6 km, followed by mostly flat terrain through primary and secondary forest. This is the only trail that allows visitors to experience both highland and lowland ecosystems. There’s also a stunning waterfall near the trailhead that’s well worth a visit.
A popular option is to enter via Los Patos and exit via La Leona for a complete Corcovado experience.
Sirena Station Trail Network
Once in Sirena, there are several short trails that connect to form a 24 km (15-mile) trail system. All of these trails are mostly flat and pass through a mix of 30-year-old secondary forest and untouched primary forest.
The chances of encountering wildlife here are remarkably high, making it one of the best areas in the park for observing animals in their natural habitat.
White-lipped Peccaries on the Sirena Trail in Corcovado, Costa RicaWest of Sirena: Beach Access and Dense Forest
On the west side of the ranger station, you can hike the Sirena Trail, which leads to the beach. From there, head north on the Guanacaste Trail to enjoy the massive Guanacaste trees—Costa Rica’s National Tree—and glimpses of the Sirena River. This trail crosses several creeks and can be muddy, so come prepared.
To return to the station, you can either take the beginning segment of the Pavo Trail (the same trail that leads to Los Patos) or loop back on the Espaveles Trail, which travels through primary rainforest and is denser than some of the others. These trails are short and very easy to hike.
East of Sirena: Longer, Interconnected Trails
On the east side of the station, you’ll find a more extensive trail network. Start with the Ollas Trail, which includes a bit of uphill hiking. It connects to the Sendero Corcovado Trail, which turns south and merges with the Río Claro Trail—the beginning of the route to La Leona. From here, you can either return westward to the station or continue south to the beach. After hiking a short stretch along the sand, the Naranjo Trail will lead you back north to Sirena.
San Pedrillo Ranger Station
At San Pedrillo Ranger Station, there’s a smaller set of trails where you can hike to spot wildlife and leisurely enjoy the lush landscapes, although these trails do not loop back to the station.
The San Pedrillo Waterfall is just 1 km from the station (2 km round trip). A longer, 7 km trail (14 km/ 8.6 miles round trip) follows the coastline on a forested path, leading to deserted beaches and crossing the San Pedrillo River. This trail can only be hiked during low tide.
La Leona Ranger Station
At La Leona Station, there are no formal trails aside from the main route to Sirena. However, a river flows toward the ocean right next to the station, offering a spot to explore or cool off after a hike.
El Tigre Trail: Scenic Views and Cultural Insight
Opened to the public in 2015, the El Tigre Trail is located at the park’s northwest edge. It starts in the community of Dos Brazos de Río Tigre, which is accessible by car from Puerto Jiménez. The trail is 8 km long and a bit more challenging than the others in the park. It enters Corcovado for only 2.5 km, but leads to a unique viewpoint unlike anything else in the area.
This trail also offers insight into two important aspects of the region’s heritage: artisanal gold mining and indigenous culture. The local community is now shifting away from mining and beginning to embrace the natural and archaeological value of their land.
