A protected space, declared a UNESCO Biosphere Reserve.
Declared a UNESCO Biosphere Reserve in 1984, the Urdaibai Reserve is one of the most spectacular places you can visit. These wetlands span over 220 square kilometres and occupy the whole length of the Oka river mouth, between the towns of Mundaka and Guernika. The predominant landscape is a spectacular mixture of sea, sand and forest, where variety and meeting points for migratory birds have turned it into a protected area. Along the mountain trails, you will find several lookout points, where you can stop and contemplate the landscape. You might also catch a glimpse of the area’s flora and fauna, including foxes, wild boars, deer, lynxes and mountain cats. The Oma forest and Santimamine Cave are two of the most popular attractions. The sea area is a great place to practice canoeing and kayaking, and you can rent all the necessary equipment on-site. This is the perfect way to discover marine wildlife, such as eels, trout and mullet, depending on where you are on the river.
