Hiking on Kea Cyclades. "Kea is a beautiful island which offers a mountainous setting ideal for trekking. The trekking paths on Kea vary in difficulty, as they may last from a few minutes to several hours. These paths cross hillsides, valleys, forests and many picturesque villages. They are usually well-signed but a map is also always required, if not a guide. Sign-posted paths of total length of 70 kilometers, at least half of which are cobblestone, run through dreamy routes and dense forests with oaks and lead to beautiful isolated beaches. There are hiking maps you can buy on the island with many routes. There are also gravel hiking roads off the beaten path."
