Three peninsulas, one easy escape
Halkidiki dangles three long fingers of land into the Aegean below Thessaloniki, and for locals it is simply the beach. The water is famously clear, the coast is backed by pine forest, and it consistently wins more Blue Flags than any other prefecture in Greece — the marker of clean, well-run beaches.
- Kassandra — the closest and busiest, with resorts, beach bars and a lively summer scene. Best if you want sand, sunbeds and somewhere to eat within easy reach.
- Sithonia — wilder and greener, with quiet coves, campsites and dramatic views. Worth the extra driving for the scenery.
- Mount Athos — a self-governing Orthodox monastic republic, closed to women and open to male pilgrims by permit only. Day visitors usually experience it by coastal boat cruise.
Getting there from Thessaloniki
There is no train to Halkidiki, so it is a car or bus trip. The first Kassandra beaches are about an hour away (roughly 78 km); Sithonia is 1.5–2 hours. KTEL Halkidikis buses serve the main resorts from Thessaloniki's bus station, but a car gives you the freedom to chase the better, quieter coves.
Weekends in July and August draw heavy traffic out of the city — leave early, and you will have the morning beach almost to yourself.
Beyond the beach
If the weather turns, the Petralona Cave in central Halkidiki is a genuine highlight: a vast cavern of stalactites where a famous ancient human skull was found — its age long debated, but recent dating makes it at least around 290,000 years old, one of the oldest human fossils in Europe.
