Discovering the Estuary's Landscapes
The Oka Estuary Natural Park showcases a diverse array of landscapes that captivate visitors with their natural beauty. The River Oka meanders through the heart of the estuary, its waters reflecting the lush greenery that lines its banks. Its tributaries, such as the Arrola and Urdaibai rivers, contribute to the intricate network of waterways that define this unique ecosystem.
Marshes and wetlands thrive in the low-lying areas of the estuary, providing a sanctuary for a variety of plant and animal life. These marshy habitats are a vital breeding ground for fish and amphibians, and they also attract numerous migratory birds.

Unveiling the Tide Mills
The Oka Estuary is home to a fascinating legacy of tide mills, silent witnesses to the ingenuity of past generations. These mills, powered by the rhythmic rise and fall of the tides, once played a crucial role in the local economy, grinding grain into flour and providing sustenance to the surrounding communities.
Their history dates back centuries, with the earliest records suggesting their existence in the 13th century. Over time, these mills became an integral part of the landscape, dotting the shores of the estuary and harnessing the power of nature to produce essential goods.
The working mechanism of these tide mills is both simple and elegant. As the tide rises, seawater flows into a reservoir, raising its level. This accumulated water is then released through a sluice gate, creating a powerful current that drives the mill's machinery. The millstones, connected to the rotating mechanism, grind the grain into flour.
Several well-preserved tide mills can still be found in the Oka Estuary, offering a glimpse into this remarkable chapter of human ingenuity. These mills, some of which have been restored to their former glory, stand as testaments to the region's rich industrial heritage.
The cultural significance of these tide mills extends beyond their practical function. They represent a tangible link to the past, showcasing the resourcefulness and adaptation of local communities to their environment. Moreover, they serve as reminders of the importance of renewable energy sources, highlighting the potential of harnessing natural forces for sustainable development.

Stroll along its narrow cobbled streets and admire the medieval architecture that tells stories of a bygone era. Oka's historic buildings, including the 13th-century church of Santa María de la Asunción, stand as testaments to the village's rich past.
Step into the bustling fish market and witness the daily catch being unloaded, a vibrant spectacle that showcases the village's deep connection to the sea. Take time to explore the local shops and galleries, where you can find unique souvenirs and artwork inspired by the estuary's natural beauty.
