16 Serene Greek Islands to Discover

Among Greece’s 6,000 islands and islets, only 227 are inhabited, and numerous ones attract an overwhelming number of tourists, which can be off-putting for some travelers. While the bustling islands might be rich in atmosphere, if you’re looking to escape the crowds, there are many other laid-back islands that offer a more tranquil experience. The primary factor keeping the masses away is often accessibility. Islands with international airports such as Crete, Rhodes, Kos, and Mykonos tend to be busier compared to less accessible locations like Milos and Syros, which are only connected by domestic flights.

Ferry routes also play a crucial role; the farther you venture from Athens or more popular islands, the quieter the spots become. So, if you’re looking for serene beach escapes or hiking adventures in picturesque landscapes, focus on less commercialized destinations. From the enchanting cycladic islands to the barely discovered Ionian gems, here are some of the best quiet Greek islands to explore.

1. Aegina

Ideal for proximity to Athens, Aegina is accessible by a half-hour catamaran ride from Piraeus, making it one of the easiest islands to visit. Surprisingly, Aegina is often overlooked by international travelers. This is unfortunate, as the island boasts numerous tavernas and delivers excellent value. Although the beaches may not be top-tier, its renowned pistachio ice cream is a must-try.

2. Astypalea

Atypically shaped, Astypalea lies between Santorini and Kos and is often regarded as an undiscovered gem. The island features historical Roman baths, a Venetian castle, windmills, and a museum brimming with antiquities. Beach enthusiasts will be treated to some of Greece’s clearest waters. Culinary highlights include ardista (stewed lentils), lambriano (stuffed lamb), and xirotigana (honey-drizzled fried dough).

3. Lipsi

Known for its mythical charm, Lipsi is where Odysseus was said to have been lured by Calypso’s enchantment.

Reaching Lipsi involves a two-hour ferry ride from Kos.

4. Andros
