Osa Peninsula Corcovado National Park

HISTORICAL PERSPECTIVE

In the beginning…

Once upon a time, in the 18th century, an awe-inspired Spanish naturalist named Fernandez de Oveido ventured into the southern regions of Costa Rica. Enchanted by the richness of flora and fauna that embraced the land, he felt a deep connection to its untamed beauty. Struck by a sense of urgency, he pleaded with the locals to protect their precious forests, but sadly, his impassioned plea fell on deaf ears. For years, the prevailing belief was that clearing the jungle was the key to improving the land, and so the forests faced a perilous future.

However, fate had a different plan in store for the Osa Peninsula. In the year 1962, a pivotal moment in history was set into motion when Alvin Wright, the manager at OPF (Osa Peninsula Foundation), extended an invitation that would forever change the destiny of this remarkable region. He beckoned two scientists, Leslie Holdridge and Joseph Tosi, to establish a field station on OPF property at Rincon for the Tropical Science Center. Together, they constructed the Rincón de Osa field station, a humble abode just south of the OPF airfield.

From 1962 to 1973, over a thousand scientists made their way to this research outpost, embarking on profound environmental land use studies and conservation-oriented endeavors. Their presence sparked a revolution, igniting the flames of an Osa conservation movement. This extraordinary community of biologists and scientists, many from foreign lands, united in a common cause: the preservation of the Osa Peninsula’s unparalleled biological diversity and natural ecosystems.

At this pivotal juncture, a significant portion of the wilderness in the Osa Peninsula was under the ownership of an American forestry company, OPF. As the idea of creating a national park emerged, fierce resistance arose on multiple fronts. However, the steadfast determination of conservationists and the growing momentum of the OSA conservation movement could not be quelled. On October 24, 1975, President Oduber signed Executive Decree (#5343-A), ushering in a new era for this neotropical paradise. The following year, Corcovado National Park was born, marking a triumph of nature over adversity.

With the establishment of the park, a beautiful transformation unfolded. EcoTourism and Conservation took root around Corcovado, nurturing the flourishing backbone of the Osa Peninsula. Today, it stands as a testament to the power of collective efforts, showcasing the harmonious coexistence of man and nature.

And so, the story of Corcovado National Park and the Osa Peninsula continues, a tale of resilience, passion, and the unyielding spirit of preservation. The legacy of those who fought for its preservation lives on, forever intertwined with the untamed beauty that makes this place a true wonder of the natural world.

Sirena Station is the best place to spot the elusive and endangered Baird’s tapir, and it’s the only ranger station where meals are available. A fresh box lunch is included and served on-site.

For those seeking an alternative, the One-Day Tour in La Leona offers a scenic hike along the coastline from Carate, where golden beaches meet vibrant secondary forest. Though this tour does not reach Sirena Station on a day hike, it follows part of the same trail and still offers fantastic opportunities for wildlife viewing, plant identification, and coastal scenery. The hike distance can be adjusted based on your pace, weather, and interest in the surrounding flora and fauna.

Each tour is led by a knowledgeable, certified naturalist guide who shares expert insights into the Osa Peninsula’s unique biodiversity. The La Leona experience typically lasts about 6 hours, including time for breaks and a picnic lunch. After your jungle journey, you’ll return to Puerto Jiménez in the afternoon.

To make the most of your adventure, consider extending your visit with an overnight stay at Sirena Station. Staying the night gives you the rare opportunity to experience the jungle at dusk and dawn—prime times for spotting wildlife such as tapirs, crocodiles, and even the elusive jaguar.
