This region has hundreds of small fishponds, once created by monks in the Middle Ages. Today they form a patchwork of water, reeds and forest – a paradise for birds, cyclists and those seeking peace and quiet. You cycle along quiet banks, see herons take flight and enjoy local specialities such as fried carp along the way.
