Halkidiki is a region in northern Greece known for having three peninsulas jutting out into the Aegean Sea. Each peninsula features Mediterranean forests, sandy beaches, and hidden coves. The most developed of the peninsulas is the westernmost one, Kassandra. Here you will find the largest hotel complexes. However, for a more traditional experience of Halkidiki, try one of the many traditional guesthouses on the seafront. Popular activities include mountain biking, hiking, watersports, open-air theatre, and visiting one of the many art festivals hosted throughout the peninsulas during the summer. Notable archeological sites include the birthplace of philosopher Aristotle as well as Stageira and Olynthus, which tourists visit to see well-preserved examples of mosaic floors. Map
