Nicoya Peninsula
Largest peninsula in Costa Rica, known for longevity and beaches.
The Nicoya Peninsula extends from Costa Rica’s Pacific coast, forming the country’s largest peninsula. It is administratively split between Guanacaste Province to the north and Puntarenas Province to the south. The town of Nicoya, one of the oldest settlements in Costa Rica, functions as the region’s primary transport and commercial hub. Ferry services connect the mainland town of Puntarenas to the peninsula, while international air travel is accessible via the airport in nearby Liberia, supplemented by smaller domestic airstrips at Nosara, Carrillo, Tamarindo, and Tambor.
The peninsula is renowned for its beaches and draws significant tourism. It also hosts numerous protected areas, including nature reserves and wildlife refuges such as Cabo Blanco, Camaronal, Cueva Murciélago, Curú, La Ceiba, Romelia, and Diriá National Park, along with conservation projects on islands within the adjacent Gulf of Nicoya. The Ostional Wildlife Refuge, a key nesting site, has recorded seasons with over 500,000 female Olive Ridley sea turtles coming ashore. Alongside Nancite Beach in Santa Rosa National Park, these areas are vital for Olive Ridley nesting, with leatherback and Pacific green turtles also common. Nesting typically occurs over three to five days. The peninsula is recognized as an Important Bird Area by BirdLife International, supporting notable populations of great curassows, lesser ground-cuckoos, Hudsonian whimbrels, Pacific screech-owls, Hoffmann’s woodpeckers, orange-fronted parakeets, long-tailed manakins, white-throated magpie-jays, and banded wrens.
Notably, the Nicoya Peninsula is identified by Quest Network as one of the world’s Blue Zones, where residents commonly live active lives beyond 100 years, a feature highlighted in Dan Buettner’s book *Blue Zones*. Other notable settlements and points of interest, roughly from north to south, include Tamarindo, Santa Cruz, Nosara, Sámara, Naranjo, Paquera, Curu, Tambor, Montezuma, Santa Teresa, and Mal Pais.

It hosts numerous protected areas, including nature reserves and wildlife refuges such as Cabo Blanco, Camaronal, Cueva Murciélago, Curú, La Ceiba, Romelia, and Diriá National Park, along with conservation projects on islands in the Gulf of Nicoya. The Ostional Wildlife Refuge is a major nesting site for sea turtles, where over half a million females have arrived in a single season; it works alongside Nancite beach in Santa Rosa National Park to protect Olive Ridley, leatherback, and Pacific green turtles, which typically nest over three to five days. The peninsula is also designated an Important Bird Area, supporting species like great curassows, lesser ground-cuckoos, Hudsonian whimbrels, Pacific screech-owls, Hoffmann's woodpeckers, orange-fronted parakeets, long-tailed manakins, white-throated magpie-jays, and banded wrens. Notably, it is recognized as one of the world’s Blue Zones, where residents commonly live active lives past age 100, a phenomenon featured in the book *Blue Zones*.
