Urdaibai (Bizkaia)

Basque Country – Urdaibai Biosphere Reserve


The Urdaibai Biosphere Reserve constitutes one of the richest natural areas in the beautiful Basque Country. Mountains of moderate height, yet quite steep, lead to a valley that ends in the Cantabrian Sea forming a wide estuary: Its cliffs, beaches and inland woods and rivers, including the marshes and river meadows, accommodate probably the most diverse scenery and environment in the Basque Autonomous Region.

Bird Watchers Paradise

You can catch sight of groups of birds on the marshlands the whole year round: sandpipers, anatidaes, birds of prey such as the osprey, warblers, herons, terns, seagulls, divers, rallidaes, auks, etc. However, September – in full autumn migration – is one of the best times to observe the different ornithological species offered by the estuary.

Surfer Paradise

The area is also and worldwide known due to the small coastal town of Mundaka that attracts surfers from all over the world who want to discover first hand what is considered Europe’s best left-breaking wave. As a matter of fact, Mundaka is venue of the “Billabong Pro Mundaka” contest – one of the most important tests of the ASP World Tour.

Places to go

Santimamiñe Caves

Designated a World Heritage in 2008, the Santimamiñe Cave, located on the right bank of the River Urdaibai, shows prehistoric rock art and an archaeological site.

TO SEE: The cave paintings here date from the Magdalenian period of the Late Palaeolithic era (13,000 BC). They include a range of animals such as bison, horses, deer, goats and brown bears. The cave also has many stunning formations of stalactites and stalagmites.

TO DO: The caves have been closed to the public since 2006. Nonetheless, hour and a half long guided tours are offered. You can also visit the chapel of San Mamés, which has been turned into an interpretative centre. There, with the aid of a sophisticated virtual tour, you’ll can travel to the inside of the cave, including the famous cave paintings.

RECOMMEND: Visit the archaeological site located at the entrance to the cave.

The Enchanted Forest of Oma

The enchanted forest of Oma was created in 1984 by Bilbao sculptor and artist Agustín Ibarrola who painted the trees bringing nature and art together.


A fantasy world where nature and art come together.

Oma Forest (in the province of Vizcaya, the Basque Country) is located in a unique setting within the Urdaibai Biosphere Reserve. There, the painter and sculptor Agustín Ibarrola wanted to bring together the technique used to paint on rocks in the Palaeolithic period with a modern trend known as “land art”, which consists of producing art on nature herself. The result: spots and lines of colour that form figures, eyes and rainbows throughout the forest, appearing before you like the spirits and fairies of ancient legend.

If you come to Oma Forest by car (it is in the village of Kortezubi, Vizcaya province), then the best thing is to leave it in the car park just 300 metres from Santimamiñe Cave. From here there is a forest track that runs to the Enchanted Forest, some three kilometres away.

TO DO: When you walk through this pine forest you will understand why people call it “enchanted”. Depending on the path you take and the direction you look, you will see that if you join together the figures appearing on different trees, they come to form specific shapes.

RECOMMEND: Although there are signs pointing out the most interesting groups of trees, remember that the magical thing about this forest is that different places appear according to the path you take. Take as long as you like and discover the forest on your own.

On April 26, 1937, during the Spanish Civil War, the town was razed to the ground by German aircraft belonging to the Condor Legion, sent by Hitler to support Franco’s fascist rebel coup. For almost four hours bombs rained down on Gernika in an “experiment” for similar atrocities carried out in subsequent wars. This crime inspired Pablo Picasso to paint “Guernica”, a painting considered one of the most important of the XX Century.
