In short: By our ranking, the most beautiful natural wonders in Greece are Mount Olympus, Samariá Gorge National Park and Meteora. The list covers 8 natural wonders. Last updated 13 October 2026.
Greece is a land of limestone and myth. The mountains of the mainland, from the Pindus to the peaks of Crete, are made largely of limestone that water dissolves into gorges, sinkholes and caves, while the movement of the Aegean plates has lifted, folded and broken the land into a jagged pattern of ranges and seas. Few places on earth have so many natural features also tied to stories: the home of the gods, the rivers of the underworld, the caves of nymphs.
Mount Olympus, the highest mountain in Greece, was believed to be the seat of the twelve Olympian gods. In Epirus, the Vikos Gorge cuts deep into the Pindus beside the stone villages of Zagori, and on Crete the Samariá Gorge runs from the White Mountains down to the Libyan Sea, narrowing to a passage only a few metres wide. In Thessaly the rock pillars of Meteora carry monasteries built on their summits, one of the most extraordinary meetings of nature and architecture anywhere.
Underground and underwater, Greece is equally rich. The Diros Caves on the Mani peninsula are explored by boat along flooded passages full of stalactites, and Melissani on Kefalonia is a cave lake whose collapsed roof lets the sun fall straight onto blue water. The Cave of the Lakes in the Peloponnese steps down through a series of natural basins. On Lesbos, the Petrified Forest preserves tree trunks turned to stone after volcanic ash buried them millions of years ago.

Όλυμπος
Greece · 24.7 km from Katerini40.083° N 22.350° E

The mountain is formed of marine sediments laid down some 200 million years ago and later sculpted by glaciers, which left high plateaus such as the Muses' Plateau at around 2,550 metres and deep gorges like that of the Enipeas above Litochoro.
Did you know? With a topographic prominence of about 2,353 metres, Olympus ranks among the most prominent peaks in Europe.
Φαράγγι της Σαμαριάς
Greece · 27.2 km from Chania35.271° N 23.961° E

Its climax is the Portes, the Gates, near the southern end: here the walls close in to only three or four metres apart while rising for hundreds of metres overhead, and the stream often fills the whole passage. Midway down lies the abandoned village of Samariá, whose last inhabitants left in 1962 when the national park was created; the gorge takes its name from the village's old church of Óssia María.
Did you know? Above the head of the gorge rise near-vertical cliffs some 900 metres high, known as the Untrodden, the goat's last great stronghold.
Μετέωρα
Greece39.712° N 21.627° E

Everything that followed had to be hauled up by hand: stone, timber, food, and eventually the monks themselves, using nets, hand-cranked winches and retractable ladders. Some of the two dozen monasteries built here took two or three generations of monks to complete — men who started the work and died long before it was finished, without ever seeing the result from the top.
Did you know? At Varlaam two brothers spent twenty-two years hoisting materials up the rock, yet the building itself reportedly went up in about twenty days.
Φαράγγι του Βίκου
Greece · 30.5 km from Ioannina39.929° N 20.741° E

The gorge lies at the heart of the Vikos–Aoös National Park, in the Zagori region. Its main section runs from between the villages of Vitsa and Koukouli to the village of Vikos, and for most of its length the stream on its floor is seasonal; only toward the end do the springs of the Voidomatis River rise and give it a permanent flow.
Did you know? The surrounding national park, founded in 1973, is one of the last strongholds of the brown bear in Europe and holds around 1,800 plant species.
Απολιθωμένο δάσος της Λέσβου
Greece39.204° N 25.874° E

The forest was buried during the early Miocene, when a series of volcanic eruptions covered this part of the island in lava flows and thick layers of ash. Over time the buried wood was mineralised and turned to stone. The vegetation they record was subtropical, very different from today's Mediterranean scrub: laurels, beeches and conifers are among the plant groups identified.
Did you know? Greece declared the fossil sites a Protected Natural Monument in 1985 by special presidential decree.
Σπήλαιο Γλυφάδα Διρού
Greece36.638° N 22.380° E

The main cave, known as Vlychada or Glyfada, is a horizontal karst system in limestone and the longest known cave in Greece, with about 15,400 metres mapped by 2007. Local people found it in 1923, and the speleologists Ioannis and Anna Petrocheilou began its systematic exploration in 1949; by the time Ioannis died in 1960, about 1,600 metres had been explored.
Did you know? Neighbouring Alepotrypa has yielded the remains of at least 170 people buried between about 6000 and 3200 BC.
Λιμνοσπήλαιο Μελισσάνης
Greece38.257° N 20.624° E

The name comes from a myth older than any of that geology: Melissanthi, a nymph in love with the god Pan, is said to have drowned herself in the lake when he didn't return her feelings — or, in a gentler local version, she was a shepherd girl who simply fell in while chasing a lost sheep.
Did you know? From the cave the water flows on underground and emerges at springs near Sami, including at Fridi beach and Karavomylos.
Σπήλαιο Λιμνών
Greece37.961° N 22.141° E

The cave is a fossil river bed developed on three levels, with a total length of about 1,980 metres, of which some 500 metres have been opened to visitors. Its character changes with the seasons: when snow on the surrounding mountains melts, water flows through it as a river with small waterfalls, and in drier months the flow stops and the stepped pools are left standing.
Did you know? The exploration was completed on Holy Thursday of 1965, and the account of the first expedition appeared in the Alpine Club's magazine To Vouno.
Places are chosen for how they look, not for how famous they are: each one has its own description and a photograph credited to its author. The order is a single world ranking that weighs the beauty of the place in curated photography together with how widely it is documented — the number of language editions of its encyclopedia article and how often that article is read in a year. The list is rebuilt as places are added, so the order and the counts on this page are always current.
