Urdaibai Biosphere Reserve (Urdaibai Reserva de la Biosfera) Tours and Activities

Slowly meandering toward the Sea of Biscay, the Oca River Estuary forms a vast wetland, the Iberian Peninsula's most important. It is protected by both the RAMSAR agreement and as a UNESCO Biosphere Reserve, the Urdaibai Biosphere Reserve (Urdaibai Reserva de la Biosfera) is home to scores of seabirds and other wildlife.

Perhaps more importantly to some visitors, it is lined with wide golden beach and quiet coves of soft sand, undulating with the tides. If you tire of tanning and swimming, climb well-marked trails into the surrounding mountains for spectacular views over the islands and sea.

This unparalleled setting has long inspired humankind to build, from today's pretty fishing villages to a ruined hermitage atop the island ofSandinderi, connected to the mainland at low tide.

Far more ancient remains include the Dolmen ofSorbituaga-Arriatara (Busturia), perhaps dating to the Iron Age, and the ancient paintings ofCave Santimamiñe. Surrounding this last are theEnchanted Forests of Oma, where artist Agustín Ibarrola works directly with nature.
