A view of a sandy beach in Halkidiki, a half hour drive from Thessaloniki. Halkidiki is known for its jutting peninsulas, which feature Mediterranean forests that give way to sandy beaches in sheltered bays. Kassandra, the westernmost peninsula, is the most developed, offering modern resorts and nightclubs. The region's notable archaeological sites include Stageira, Aristotle’s birthplace, and Olynthus, known for its well-preserved mosaic floors.
