Hidden in the lush hills above Montezuma lies more than just a patch of protected forest—it’s the legacy of two dreamers whose love for each other and Costa Rica’s wild places helped ignite a conservation revolution. The Nicolás Wessberg Nature Reserve isn’t only a sanctuary for monkeys, ocelots, and towering trees; it’s the living story of Karen Mogensen and Olaf “Nicolás” Wessberg, a Danish-Swedish couple who turned a tropical fantasy into a powerful reality.
Their journey transformed deforested cattle land into thriving forest, sparked the creation of Costa Rica’s first private reserve, and inspired a national passion for protecting nature. This is the tale of how two determined individuals helped shape an entire country’s environmental future—and why visiting their beloved reserves today is an unforgettable experience.
The Scandinavian Love Story That Sparked Costa Rica’s Conservation Revolution
Tucked away in the emerald hills above Montezuma lies a piece of Costa Rica’s living history: the Nicolás Wessberg Nature Reserve. It’s more than just forest trails and ocean views — it’s the legacy of two dreamers whose love for each other and the natural world helped transform Costa Rica into the conservation powerhouse it is today.
This is the story of Karen Mogensen and Olaf “Nicolás” Wessberg — and how their bold vision gave us not only this reserve, but an entire national park movement.
From Nordic Winters to Tropical Dreams
Picture this: a Danish woman, Karen Mogensen, born in Holstebro, meets a Swedish man, Olaf (Nils Olof) Wessberg, and together they dream of life under tropical skies. In 1952, they marry and set off on a grand adventure, traveling through the Americas in search of their paradise.
By 1955, they find it — in Costa Rica, on the Nicoya Peninsula, north of Montezuma.
Life wasn’t easy at first. They lived simply, growing fruit, channeling water from mountain streams, and pouring their energy into caring for the land. But they felt they’d discovered something precious: a place worth fighting for.
Planting Seeds of Conservation: The Birth of Cabo Blanco
During the early 1960s, Karen and Nicolás watched the forests around them fall to cattle ranching and logging. Instead of despairing, they acted.
Between 1960 and 1963, they scraped together funds and purchased 1,250 hectares of land at Cabo Blanco. With help from friends and organizations in Scandinavia, they fought to protect this forest jewel, succeeding in 1963 when Cabo Blanco became Costa Rica’s first private nature reserve.
They didn’t know it then, but their efforts would ignite a national passion for conservation that would ripple far beyond their own lifetimes.
Tragedy and Tenacity
Nicolás’s commitment to conservation took him further afield, including fierce advocacy for saving what would become Corcovado National Park. Tragically, his fight cost him his life. In 1975, while campaigning for conservation causes, he was assassinated.
Karen, devastated but determined, closed the couple’s small hotel in Montezuma and turned her attention to protecting their own land near the town.
Her efforts would eventually become the Nicolás Wessberg Nature Reserve, ensuring the forest they nurtured together would remain wild and protected.
The Nicolás Wessberg Nature Reserve: A Quiet Paradise
In 1994, Costa Rica officially declared Reserva Natural Absoluta Nicolás Wessberg, covering around 0.5 km² of coastal cliffs and moist tropical forest just north of Montezuma.
This reserve, once the couple’s private farm, is now a haven for wildlife like:
- White-faced and howler monkeys
- Peccaries and coatis
- Ocelots and margays
- Hundreds of bird species
It’s also the final resting place of Karen and Nicolás — fitting for two people who gave their lives to these forests.
Honoring Karen: The Karen Mogensen Nature Reserve
Karen’s name lives on not just in Montezuma, but also inland, where the Karen Mogensen Nature Reserve flourishes thanks to the efforts of ASEPALECO (Ecological Association of Paquera, Lepanto & Cóbano).
After Karen’s death in the mid-1990s, the reserve was dedicated to her memory. Spanning approximately 960 hectares, it protects vital tropical dry and moist forests, creating a corridor that links Cabo Blanco to Barra Honda National Park.
Highlights of the Karen Mogensen Reserve include:
- The stunning Velo de Novia (Bridal Veil) waterfall, plunging 84 meters into a lush pool
- Trails winding through dense forest, alive with over 240 species of birds
- The remote Cerro Escondido Lodge, accessible only by a scenic hike or horseback ride
ASEPALECO’s work goes beyond conservation, providing crucial water protection for local communities and educating visitors on the importance of preserving these fragile ecosystems.

Frequently asked questions
Karen Mogensen, from Denmark, and Olaf “Nicolás” Wessberg, from Sweden, were pioneers of conservation in Costa Rica. They moved to the Nicoya Peninsula in the 1950s and dedicated their lives to protecting tropical forests, founding the country’s first private nature reserve at Cabo Blanco in 1963.
The Nicolás Wessberg Nature Reserve lies just north of Montezuma on Costa Rica’s Nicoya Peninsula. It’s nestled between lush coastal hills and the Pacific Ocean, offering a mix of tropical forest and dramatic coastline.
The reserve covers approximately 0.5 square kilometers (50 hectares). Though small, it protects important coastal and forest habitats once part of Karen and Nicolás’s original farm.
