Cabo Blanco Nature Reserve

The Cabo Blanco Nature Reserve – The Facts

We are lucky to live very close to the stunningly beautiful Cabo Blanco Nature Reserve, which is located on the southern tip of the Nicoya Peninsula of Costa Rica.  The reserve protects a myriad of animal and plant life, both on land and in the ocean.  The walking trails  through the protected forest are a must for anyone visiting our area.

Here are some interesting facts on Costa Rica’s first national nature reserve.

How Big is the Cabo Blanco Reserve?

The reserve is 3,140 acres of protected forest (12.7km2) and 4,420 acres of protected ocean (17.9km2).  95% of the Reserve is off-limits to visitors – this is to ensure that the wildlife continues to live and prosper without interruption.  There is however a Biological Station located within the reserve, which provides facilities for scientists who come to study the incredible biodiversity of the tropical forest and ocean.  The San Miguel Biological Station is equipped with classrooms, laboratories, a reference library and a bunk house for up to 30 people.

What Creatures Live in the Reserve?


About 150 different species of trees have been identified within the reserve.  The majority of Cabo Blanco is secondary forest that is around 60 years old.  Only 15% of the reserve is primary forest.  The remaining primary forest is located at the highest, most inaccessible area of the reserve.


Mammals that live within the reserve include howler monkeys, white-faced monkeys, white-nosed coati, white-tailed deer,  pacas, armadillos, anteaters, coyotes, porcupines, raccoons and coatis.  There are also wild cats such as ocelots, jaguarundis and margay cats.  These cats are so shy that they often get caught on night cameras, but are unlikely to be spotted during the day.

Around 240 bird species have been recorded in Cabo Blanco.  It is inhabited by large numbers of brown pelicans, frigate birds, laughing gulls, common terns, ospreys and Costa Rica’s largest community of brown boobies making it a very important seabird sanctuary.  Along with seabirds you can also see magpie jays, motmots, long-tailed manakins, egrets, crested caracaras, black-headed and elegant trogons, chachalacas, ringed kingfishers and various types of parrots and parakeets.

Marine Life: 

The protected waters are home to many species of fish, large quantities of lobster, giant conches, crabs and mollusks.  On occasions there have been great migrations of manta rays, jumping spotted eagle rays, as well as dolphins and whales in the waters close by the Cabo Blanco island.

Why is it Called the Cabo Blanco Reserve?

The reserve is named after the island Cabo Blanco, which is located 1.6 km from the reserve’s southern tip. Since the times of the Conquistadores it has been known as the “White Cape” because encrusted bird poo covers the rocks turning them white.

What is the History of the Reserve?

The reserve was created in 1963 thanks to a campaign started by a Swedish man named Olaf Wessberg and his Danish wife Karen Mogensen.

In the 1950s the government encouraged local people to move to the remote forest lands of the Nicoya Peninsula.  A family that cleared the forest for farm or pasture was rewarded with ownership.  The emphasis was to develop and increase agricultural production, with little concern for the conservation of natural habitats.  As a result, in the early 1960s the peninsula was being depleted of its natural forest and only a small area of primary forest remained in the least accessible areas of the Cabo Blanco.

Olaf and Karen arrived in Costa Rica in the early 1960s, and bought a farm near Montezuma.  They often explored the Cabo Blanco area and were impressed by the abundant wildlife and the enormous size and diversity of the trees there.  Olaf decided to preserve the area. With the aid of foreign conservation organizations he bought 1,250 hectares of land and after a tireless campaign of lobbying the Costa Rican government the Cabo Blanco was given the status of an Absolute Nature Reserve in 1963.

This was the first major conservation project in the country and led to the development of Costa Rica’s extensive national park system.  Costa Rica now has 27 national parks, 58 wildlife refuges, 32 protected zones, 15 wetland area/mangroves, 11 forest reserves and 8 biological reserves, as well as 12 other conservation regions that protect the distinctive and diverse natural habitats found throughout the country.    

Sadly Olaf was assassinated in 1975, whilst working towards making a public reserve out of what is now Corcovado National Park in the Osa Peninsula.  Undeterred by her husband’s death his wife Karen and many others continued with his conservation projects.

  • Is the farmland near the reserve in Cabuya protected? Can it be developed? I am purchasing a house close to the farmland near town and am concerned about future development.

    • Hi Kim,

      All land and ocean areas inside the reserve are protected. It is possible to purchase land outside of the reserve and develop. Before purchasing consider asking for a Uso de Suelo to find out what the building restrictions are for your particular piece of land.

      Good luck with your project!
