In the 18th century a network of beautiful arched stone bridges and paved donkey paths (kalderimis) was built throughout Pilion in order to bring produce down from the higher areas. Through time a great deal of these kalderimi’s have been destroyed, neglected or tarmacked, but some parts are still intact and an occasional section is being renovated. Some have been signposted as footpaths and are included on maps. For our walks we make use of kalderimis, unpaved paths and roads, forest paths and goat tracks and sometimes of the old railway track, where a touristic service now operates in the weekends. The eastern side of Pilion is more rugged and steeper than the western side, so walks there often span larger differences in height.
