In the hills above Antiparos village, about 8km from the port, lies one of the oldest tourist attractions in Greece — and one of its most genuinely surprising. The Cave of Antiparos has been drawing visitors since antiquity: ancient Greeks left votive offerings here, Lord Byron carved his name into the walls in the early 19th century, and the Marquis de Nointel celebrated Christmas Mass here in 1673 with a congregation of 500. The stalactites are up to 45 million years old. Coming here is not a sideshow — it's one of the highlights of any visit to the Cyclades.
Descending into the Cave
A path of 411 steps descends 160 metres through a series of chambers of increasing drama. The largest chamber is roughly 60 metres wide and 30 metres high — you hear it before you see it, as the scale becomes apparent only when you step through a narrow passage into open space. The air changes as you go deeper: cooler, stiller, faintly mineral.
The formations include stalactites hanging from the ceiling and stalagmites rising from the floor of extraordinary size and variety. Some resemble curtains of folded stone, others hang in slender needles, others bulge into columns where the two have joined over millennia. The colours shift from pale cream near the entrance to deep amber and rust further in, stained by minerals seeping through the limestone above. It is genuinely unlike anything else in the Aegean.
History and Legends
The cave has been inhabited or visited since at least the Neolithic period — ancient pottery and offerings were discovered inside during early excavations. Inscriptions carved into the walls by 16th and 17th century travellers, including the Russian Tsar's ambassador, are visible near the entrance, a layered record of centuries of wonder.
A marble plaque marks the spot where the Marquis de Nointel's extraordinary Christmas service was held in 1673 — an event attended by 500 people, complete with music and candles in the depths of the earth. Lord Byron's inscription, left during his time in the Aegean in the early 1800s, is one of the most famous, though conservation efforts have now fenced off the most vulnerable areas to protect what remains. The cave feels, even today, like a place people have always come to and always felt compelled to mark.
Open daily May–October, approximately 10am–4pm. Entry: €6 adults, €3 children 6–12, free under 6. The cave interior is always around 17°C — bring a light layer even in August. Wear closed shoes, as the steps can be slippery. Allow 45–60 minutes for a complete visit. Getting there: rent a scooter from Antiparos village (8km, clearly signposted) or take the tourist minibus that runs from the port in high season. From Antiparos Houses, it's about 15 minutes by scooter.
Tips for Your Visit
Go in the morning — ideally between 10am and 11am — before the day-trippers from Paros arrive. The cave gets noticeably crowded from 1pm onward in July and August, and the narrow passages are more pleasant to move through when it's quiet. Photography is allowed but tripods are not permitted inside. The descent is on proper stairs with handrails and is well maintained, but it is not suitable for those with significant mobility difficulties. Children generally love it — the scale is dramatic and the whole experience is accessible enough to keep even young visitors engaged from start to finish.
Combine Your Day
The cave works perfectly as the anchor for a full day out. Pair a morning visit with a swim at Agios Georgios beach, just 3km from the cave entrance — a sheltered, sandy bay that's rarely crowded even in high season. From there, head back into Antiparos village for lunch in one of the harbour tavernas before an afternoon on the water.
For a longer day, the cave pairs beautifully with a boat trip to Despotiko island, just off the southwest coast of Antiparos, where excavations have been uncovering a significant Archaic sanctuary for the past two decades. Ancient sites above ground and 45-million-year-old formations below it — Antiparos rewards curiosity in every direction.
