Halkidiki in northern Greece, close to the city of Thessaloniki, is made up of three 'fingers' jutting into the Aegean Sea.
The eastern-most peninsular, Mount Athos, also known as the Holy Mountain, is a semi-independent monastic state and a UNESCO World Heritage Site.
Its forested slopes are home to 20 monasteries and some 1,700 monks. You can take a boat trip around the perimeter of this fascinating Mount Athos, departing from Ouranoupolos.Halkidiki's other main attraction is Petralona Cave,
with almost 2km decorated with impressive stalagmites and stalactites. It lies a short distance inland from Nea Moudania, just north of Kassandra peninsular.
