The Iturraran Botanical Garden holds one of the largest collections of endangered ornamental plants in the Basque Country.
The Agorregi complex utilizes a gravity-based water system to power its mechanical bellows and hammers, dating back to the medieval era.
The park contains the remains of pre-Roman tumuli and burial mounds, indicating human presence in the area dating back thousands of years.
The vegetation transition reflects the park's specific location, acting as a climatic barrier between the sea and the interior mountains.
The park is home to the Pottoka, an ancient breed of semi-wild mountain pony native to the Basque Country.
Pagoeta Natural Park is a protected area in Gipuzkoa centered around the Iturraran Botanical Garden, which contains over 5,000 species of plants from around the world. The reserve spans 2,860 hectares, encompassing diverse ecosystems ranging from Atlantic beech forests to coastal grasslands. It features the Agorregi complex, a 16th-century industrial site consisting of restored water mills and iron forges that demonstrate historical hydraulic technology. The terrain is characterized by steep limestone ridges and deep valleys carved by the river, offering panoramic views of the Cantabrian Sea. The Iturraran Farmhouse, dating back to the 18th century, serves as the park's interpretation center and gateway to the botanical collections. Agriculture and livestock farming continue within the park boundaries, integrated with conservation efforts. Trails provide access to both the dense forest canopy and the open meadows maintained by traditional grazing practices.
