Planning a trip to the Greek islands can be intimidating, that’s way I’m here! With more than 200 inhabited isles (and about 6,000 islands and islets in total), the magnitude of the archipelagos is astounding. Each has its own character and aesthetic, from Cyclades islands dotted with white-and-blue houses to the lush and green Ionian Islands to the castle-lined Dodecanese. Overall, Greece has six main island groups, plus a significant stand-alone: Crete. It's generally easiest to travel between islands within one group than to hop between archipelagos. Here are some of the best Greek islands to visit, including what each island group is known for.
The Cyclades Islands
This archipelago is the most common first stop for American travelers in Greece, with two of the most-visited islands: Mykonos and Santorini. A group of about two dozen inhabited islands (and 220 total isles), this bunch looks like all the postcards of Greece you've seen: white churches with blue domes and pink bougainvillea vines shading secluded side streets.
Mykonos is known for its nightlife and see-and-be-seen beaches, but it also has a gorgeous Cycladic village in its center, with windmills and winding lanes designed to confuse pirates centuries ago. Santorini is romantic and luxurious, beloved by honeymooners lounging in their private pools overlooking the caldera. For those looking for alternatives to Mykonos and Santorini, options abound. Up-and-coming Milos has otherworldly beaches and the famed sea caves, Tinos is the site of a famous Church of the Virgin Mary, and the rustic Lesser Cyclades (Koufonisia, Donousa, Schinoussa, and Iraklia) are great for camping. There are large islands, like Naxos and Syros, the archipelago's capital, and tiny ones with very little tourism, like Sikinos.
Saronic Gulf Islands
The Nantucket of Greece, car-free Hydra is tiny but mighty. Spetses has green pine trees, yachts parked in the harbor, and traditional horse-drawn carriages along its waterfronts. Family-friendly Poros, with tree-shaded beaches and a charming town dominated by a clock tower, is popular among sailing aficionados. Aegina, the closest island to Athens, has a large port town, sandy beaches, and the ancient Temple of Aphaia dedicated to the goddess of Athena. Because the Saronic Gulf islands are so close to Athens, getting here is simple — a hydrofoil from the port of Piraeus ferries you from Athens to each of these destinations.
The Ionian Islands
On Corfu, you'll want to wander the streets of the island's UNESCO-protected Old Town. Near Corfu, tiny Paxos is covered in olive trees, with three charming bays and a satellite island, Antipaxos, known for its translucent waters. The largest of the Ionian Islands in size, Kefalonia is one of the most beautiful places to visit in Greece and has semi-wild horses running around Mount Ainos in its center. Zakynthos is home to Navagio Beach (also known as Shipwreck Beach), accessible only by sea, and iconic blue caves you can swim through. Lefkada, connected to the mainland by a bridge, has woodland villages and some of Greece's best beaches along its shores. Small Ithaka, known to Homer fans as the home of Odysseus, is still relatively undiscovered. Finally, Kythera is the outlier — it looks more Cycladic than Ionian and is more easily reached from the Peloponnese.
Corfu, Kefalonia, Zakynthos, and Kythera all have airports, which receive domestic flights from Athens as well as international charters and airlines.
That leaves The Sporades Islands, The Northeast Aegean Islands, and The Dodecanese Islands left to explore.
