Greece has more coastline than almost any country in Europe, and the quality is remarkably consistent — turquoise water, white pebbles or golden sand, tavernas steps from the shore. The hard part is not finding a good beach; it is choosing between them. This guide covers the stand-outs by island and region so you can match your beach to the kind of trip you're after.
Santorini — volcanic drama and caldera swimming
Santorini's most famous beaches are black or red, coloured by ancient volcanic activity. Perissa and Perivolos on the east coast are long, black-sand stretches lined with sunbeds and beach bars — easy to reach, lively and good for families. Red Beach near Akrotiri is smaller and more dramatic, with rust-red cliffs rising directly from the water. For caldera swimming, the hot springs off Nea Kameni are unlike anything else in Greece — you reach them by boat and float in warm, mineral-heavy water with the volcano behind you.
Mykonos — glamour beaches and quieter coves
Paradise Beach and Super Paradise are Mykonos's party beaches — sunbeds, DJs and cocktails from midday. They are exactly what they promise and unapologetically so. For something quieter, Agios Sostis in the north has no sunbeds, no bars, no road — just a beautiful arc of sand reached by a dirt track. Elia, on the south coast, is a long, calm beach that attracts a more mixed crowd and has enough space to spread out even in high season.
Crete — the island that has everything
Crete is large enough to feel like a country in its own right. Elafonissi, in the far southwest, is the headline act — shallow lagoon water, pink-tinged sand and mountains behind. It is busy in August but genuinely beautiful. Balos, reachable by boat or a rough 4x4 track, is an extraordinary lagoon where Crete meets two smaller islands. On the north coast, Falassarna is a wide, sheltered beach ideal for families, while Vai in the east sits in front of Europe's largest natural palm forest.
Halkidiki — mainland Greece's best-kept secret
Most international visitors overlook Halkidiki for the islands, but the three-pronged peninsula southeast of Thessaloniki has some of the clearest water in the Mediterranean. Vourvourou on the middle finger (Sithonia) is a near-perfectly sheltered bay; Kavourotrypes nearby is a series of rocky coves with turquoise water that look like something from the Maldives. The third prong, Athos, is a monastic republic closed to women and restricted to men with special permits — but the views from Sithonia across to it are extraordinary.
Getting between the islands
Ferry is the default transport between islands. The Athens port of Piraeus connects to most major islands daily; high-speed catamarans halve travel times to Mykonos and Santorini. For Crete, direct flights from most European cities are abundant in summer. Between islands, small inter-island ferries run frequently in July and August but thin out sharply in shoulder season — always book a day ahead in peak months.
