This is the least chartered corner of Greece — 78 boats, the smallest of our Greek regions — and it is two separate pieces of water. In the west, Halkidiki: the three-fingered peninsula south of Thessaloniki, with bases at Nikiti, Porto Carras and Miraggio. In the east, Thrace: Kavala, Keramoti and Avdira, facing the island of Thasos. They are not a single cruising ground and most weeks pick one.
It is also a sailing region rather than a lifestyle one. Sixty-two of the 78 boats are monohulls, averaging 13.4 metres, with rates from about €910. The fleet is the oldest in Greece at a 2012 average build year, which is what happens in a market with little turnover and no superyacht trade.
The feature that makes this region unlike anywhere else in the catalogue is the easternmost of Halkidiki's three fingers. Mount Athos is a self-governing monastic republic — twenty medieval monasteries, no secular residents, and a set of rules that are a thousand years old and still enforced. Vessels must keep 500 metres off its shore, and patrol boats enforce that distance. No woman may set foot on Athonite land. Going ashore at all requires a Diamonitirion permit issued by the monastic authorities, granted by purpose and nationality, with pilgrims and researchers given priority.
You can sail past it, and it is worth doing: the monasteries are built into cliffs above the water and the view from 500 metres out is the view almost nobody gets. But treat the boundary as absolute. If you have women aboard, the sensible plan is to admire the coast from the legal distance and not to attempt a landing.
The rest is a quiet, green, underpriced alternative to the Aegean everyone knows: the Sithonia coast, Thasos across the strait, and the Mount Olympus skyline behind you on a clear day.
