Devil's Table , Set at the highest point in the Ayvalik vicinity and formed by a volcanic eruption, Seytan Sofrasi offers a magnificent unobstructed 360 degrees panorama across the convoluted local coastline of bays, headlands and islands, including the Greek island of Lesvos (Mytelini). The view is particularly impressive at sunset. The legend is the Devil liked the view so much, he ate his dinner on the top and left his footprint upon leaving.
