July and August are the most popular months. Heat, crowds, energy — but also higher prices.
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.
