Kavala Lighthouse stands on the Panagia peninsula, giving one of the old town's easiest sea-facing viewpoints. The lighthouse itself is modest, but the site frames the harbor, rooftops, and Aegean horizon in a compact walk.
It is a worthwhile pause while exploring the old quarter around the house of Mehmet Ali and the castle. Go for the view, breeze, and sense of Kavala as a city wrapped around the water.
