Hiking & Trekking
Kea has an extensive network of sign-posted trails which makes the island the ideal destination for everyone who loves hiking. The paths go through forests of oak trees, meet springs with potable water, old country churches, cottages and ancient towers and almost all of them end up in picturesque and isolated beaches. The network of footpaths iincludes 12 routes of a total length of 81 km, many of which are stone-paved. The footpaths were part of an ancient road network that in the 7th – 6th century B.C. connected the cities-states.
