Sithonia tends to be 1-2°C cooler than Kassandra due to denser pine forest cover. The Vardaris (north wind) can bring sudden cool spells even in July.
Summer (June–September) for beaches and swimming. July–August is peak. May, early June, or September give great weather with fewer crowds and 30–50% lower prices.
Fly to Thessaloniki (SKG), then 1–2 hours by car. Car rental from ~€25/day. Alternatively bus (KTEL Halkidiki), but schedules are limited. Detailed routes in /from guides.
Kassandra: lively, family-friendly, more touristy. Sithonia: quieter, more exotic, better nature. Athos: remote, ideal for tranquility. Browse /listings — book directly with owners, no booking fees.
Highly recommended. Beaches and villages are spread out, buses are sparse. If you skip the car, pick accommodation near a popular resort (Kallithea, Hanioti, Nikiti) with restaurants and beaches in walking distance.
