Greece’s scattered islands have captivated imaginations for millennia, serving as the backdrop for countless myths and legends that still resonate today. While Santorini and Mykonos draw crowds with their iconic views, scores of lesser-known islands harbor deep connections to Greek mythology.
These hidden gems offer not just pristine beaches and authentic villages but living landscapes where ancient stories feel tangibly present. From caves that are said to lead to the underworld to shores where gods were born, these islands connect visitors to narratives that have shaped Western consciousness for over 3,000 years.
Here is a list of 20 hidden Greek islands with powerful connections to ancient mythology that remain largely overlooked by mainstream tourism.
Ithaca
While not entirely unknown, Ithaca receives only a fraction of the visitors that flock to neighboring Kefalonia despite being the legendary home of Odysseus. The island’s rugged terrain and secluded coves perfectly match Homer’s descriptions in The Odyssey, with locals still pointing to specific sites mentioned in the epic.
The Spring of Arethusa on the island’s southern coast is said to be where Odysseus’s faithful swineherd Eumaeus watered his pigs, while the Cave of the Nymphs supposedly housed the treasures Odysseus brought back from his decade-long journey home.
Lemnos
This North Aegean island was the legendary home of Hephaestus, who established his forge here after being cast from Mount Olympus. The island’s volcanic landscape, with its otherworldly terrain of red rocks and thermal springs, made a fitting workshop for the god of metallurgy and fire.
Local tradition identifies a specific sea cave on the northern coast as the entrance to Hephaestus’s underground forge, where he crafted magical weapons and armor for gods and heroes with the help of the one-eyed Cyclopes.

Icaria
Named for the tragic Icarus, who plummeted into the sea nearby after flying too close to the sun with wax wings, this remote island between Mykonos and Samos guards its mythological heritage fiercely. The southwestern shores where Icarus’s body supposedly washed ashore feature dramatic cliffs and isolated beaches accessible only by boat.
Modern Icarians embrace their island’s connection to this cautionary tale, viewing their home as a place where human ambition meets natural limits—a philosophy reflected in their famously unhurried lifestyle that has made them one of the world’s longest-lived populations.
Gyaros
This tiny uninhabited island in the Cyclades served as the mythological site where Leto gave birth to the twins Apollo and Artemis after being pursued by the vengeful Hera. Ancient texts describe how the barren, floating island was anchored to the seabed by Zeus to provide sanctuary for Leto’s labor.
Today, the island’s stark beauty and isolation—accessible only by private boat—evoke the primordial landscape described in the myth, with ruins of an ancient temple to Apollo visible on its eastern headland.
Samothrace
This mountainous northern island housed the Sanctuary of the Great Gods, where the Samothracian Mysteries—secret religious rites promising divine protection at sea—were performed for over a thousand years. The island’s mist-shrouded peaks were said to be where Poseidon sat to watch the Trojan War unfold, as Homer describes in the Iliad.
Despite yielding the famous Winged Victory statue now in the Louvre, Samothrace remains surprisingly untouristed, with its wild landscape and ancient ruins creating an atmosphere where the boundary between myth and reality seems to dissolve.

Skyros
This rugged island in the Sporades holds the tomb of the legendary hero Theseus and was where young Achilles was hidden by his mother Thetis, disguised as a girl to prevent him from joining the Trojan War. Local tradition identifies specific caves where Achilles lived among the daughters of King Lycomedes before Odysseus tricked him into revealing his identity.
The island’s distinct culture—including its famous miniature horses mentioned in ancient texts—maintains connections to prehistoric Aegean civilizations that formed the historical basis for many Greek myths.
Polyaigos
This uninhabited island near Milos derives its name from the Greek words for ‘many goats,’ referencing the mythological herd belonging to the sun god Helios that grazed on its hills. Ancient texts describe how Odysseus’s crew incurred the god’s wrath by slaughtering these sacred animals for food, leading to their eventual destruction.
The island’s limestone cliffs create celestial light effects at sunrise and sunset that ancient seafarers interpreted as manifestations of Helios’s power, while the landscape remains essentially unchanged since mythological times.
Makronisos
This small island off the coast of Attica served as the mythological prison of Helen of Troy before Paris spirited her away to initiate the Trojan War. Ancient writers described the island as sacred to Helen, with a temple complex dedicated to her worship as a goddess rather than merely a mortal beauty.
The island’s stark landscape and troubled modern history as a political prison camp create a haunting atmosphere that evokes its mythological past as a place of beautiful captives and fateful decisions with world-changing consequences.

Patmos
While known for its connection to Christian tradition as the site where St. John wrote Revelation, Patmos has deeper roots in Greek mythology as an island sacred to Artemis, goddess of the hunt. The labyrinthine Cave of the Apocalypse, where John received his visions, was originally associated with Artemis’s worship, with ancient inscriptions of the goddess still visible on its walls.
Local fishermen maintain traditions connecting the island’s unusual rock formations to mythological events, including one resembling a deer that supposedly commemorates a hunter transformed by the offended goddess.
Dia
This uninhabited island just north of Crete played a crucial role in the Theseus and Ariadne myth, serving as the site where Theseus abandoned his lover after she helped him defeat the Minotaur. Ancient sources describe how the heartbroken Ariadne was then discovered on Dia’s shores by the god Dionysus, who made her his immortal bride.
Underwater explorations around the island have revealed ancient harbor structures that some archaeologists connect to the historical basis for Crete’s legendary maritime empire described in the Theseus myth.
Chryse
This phantom island mentioned in ancient texts reportedly sank beneath the waves near Lemnos, taking with it a magnificent temple to Apollo. Mythological accounts describe it as the place where Philoctetes, keeper of Heracles’s bow, was abandoned by the Greeks on their way to Troy after suffering a snake bite that wouldn’t heal.
Recent geological studies suggest the island may have actually existed before being submerged by volcanic activity, with local fishermen occasionally reporting glimpses of ancient ruins visible beneath clear waters during specific tide conditions.

Paros
While more developed than others on this list, Paros contains overlooked mythological sites, including the quarries that produced the flawless white marble from which the great sculptor Praxiteles carved his famous statue of Aphrodite. Local legends claim these quarries were discovered by the Cyclops Arges, who recognized the stone’s unique quality after a lightning bolt from Zeus illuminated the mountainside.
The island’s ancient marble sanctuaries dedicated to Apollo and Artemis maintain physical connections to mythological traditions dating back to when the gods themselves supposedly walked these shores.
Spinalonga
This tiny fortress island off Crete’s northeastern coast appears in no major myths but features in local folklore as the home of Talos, the bronze automaton created by Hephaestus to protect Crete by hurling boulders at approaching ships. Fishermen’s tales describe hidden underwater caves containing melted bronze—supposed remnants of the fallen giant after he was defeated by the Argonauts.
The island’s later history as a leper colony created an atmosphere of isolation and otherworldliness that reinforced its connection to supernatural guardians and forbidden territories from Greek mythology.
Psathoura
This small volcanic island in the Northern Sporades is associated with ancient accounts of Aeolus, keeper of the winds, who supposedly used the island’s unique acoustics to monitor weather patterns across the Aegean. The island’s perfectly circular shape—unique in the Mediterranean—was attributed in antiquity to the god’s design, creating a natural amphitheater where approaching storms could be heard from great distances.
Local sailors still report unusual wind patterns and acoustic phenomena around the island, which science explains through its volcanic geology, but tradition attributes to Aeolus’s continuing presence.

Antikythera
Famous for yielding the world’s oldest known computer—the Antikythera Mechanism—this tiny island between Crete and the Peloponnese features in regional myths as a sanctuary of Apollo, where the god delivered oracles through unusually vivid dreams. Ancient texts describe a temple complex where pilgrims would sleep in order to receive divine guidance through their dreams, with priests interpreting these visions through complex mathematical formulas.
The island’s position at the convergence of major Mediterranean currents made it a natural collection point for flotsam, which mythology transformed into messages from the gods.
Agios Efstratios
This remote island in the northern Aegean was considered in antiquity to be one of the places where the goddess Cybele was worshipped in her most primal form. Island folklore describes how the goddess’s priestesses would summon storms to wreck ships that failed to make appropriate offerings when passing the island.
Archaeological discoveries of unusual ritual objects support the island’s connection to prehistoric goddess worship that later evolved into the Cybele myths. The island’s isolated communities preserved distinctive religious practices, blending Orthodox Christianity with older traditions traceable to ancient mythology.
Gavdos
As Europe’s southernmost point, this tiny island south of Crete was identified in Homeric geography as Ogygia, the island where the nymph Calypso kept Odysseus captive for seven years. The island’s remote location and lush microclimate create the paradise-like setting described in The Odyssey, with natural caves along its coastline matching Homer’s description of Calypso’s home.
Modern Gavdos remains one of the Mediterranean’s least developed destinations, attracting free spirits who sometimes live in these same caves during summer months, creating an echo of the myth’s themes of isolation and timelessness.

Anafi
According to mythology, this small Cycladic island was raised from the sea by Apollo to provide shelter for the Argonauts during a violent storm. Its name derives from the Ancient Greek meaning ‘revelation,’ referencing its sudden appearance.
The island’s striking monolith, Mount Kalamos, features in local legends as the petrified body of a Titan defeated by Apollo, with geologically unusual rock formations across the island attributed to the battle between god and giant. Modern Anafi remains difficult to reach, preserving an atmosphere that makes its mythological origins feel plausible even to skeptical modern visitors.
Alimia
This uninhabited island near Rhodes supposedly housed one of the gardens of the Hesperides, where golden apples conferring immortality grew under the protection of a never-sleeping dragon. Local tradition identifies a specific valley where unusual ancient olive trees with golden-hued fruit still grow, supposedly descended from the mythological orchard.
The island’s freshwater springs, unusual for the arid Dodecanese, fueled its mythological association with abundance and divine blessing, while its strategic position made it historically important despite its small size.
Psara
This small island west of Chios was associated with the myth of Glaucus, a fisherman who achieved immortality after eating a magical herb and transformed into a prophetic sea god with fish-like features. Island folklore describes specific coves where Glaucus would appear to fishermen, offering predictions about weather and fish migrations.
The island’s unusually rich marine ecosystem, produced by unique underwater currents, provided the natural foundation for myths about supernatural abundance and communication between humans and sea creatures that continue to influence local fishing practices.

The Mythology in Today’s Landscape
These hidden islands preserve connections to Greek mythology not just through archaeological remains but through living landscapes that continue to evoke ancient stories. From caves that seem to lead to the underworld to bays where the light creates supernatural effects, the physical features that inspired myths thousands of years ago remain largely unchanged.
While mass tourism transforms better-known Greek destinations, these overlooked islands offer authentic experiences where mythology feels less like distant stories and more like genius loci—the spirit of place—still present in the wind, waves, and rock formations that first inspired these enduring narratives. Through these lesser-known islands, modern travelers can experience the same natural wonder that once moved ancient Greeks to populate their world with gods, heroes, and monsters.
