    Mountain biking

    Nestled in the landscape of the Navia river valley, the medieval defensive watchtower, the Tower of Doncos is a unique historical complex.

    Mountain biking

    Remains of a 14th-century fortress that once stood watch over the Neira Valley. Although in ruins, it still retains the legendary air of the old Galician lineages. Cyclist's tip: the climb is demanding, but arriving and finding this solitary tower makes the journey seem twice as worthwhile.
