The Parque de Doña Casilda is the most famous park in Bilbao. The park is also called parque Casilda Iturrizar, named after the benefactor who donated this park to Bilbao. The park was built between 1912 and 1920 in English romantic style and is an oasis of peace in the city. It is located near the Guggenheim Museum and the Maritime Museum on the Nervión River in the Indautxu district. It is a park to stroll through the 8.52 hectares via the many paths and along the decorative fountain or to watch the birds at the duck pond. Since 1940, the museum of fine arts, the Museo de Bellas Artes de Bilbao, has also been located next to this park.

A panoramic walk along the banks of the reservoir. Mainly in the shade of native trees, just listen to the birds singing.
