A cave on screen offers something no set can quite reproduce: real darkness, real water and stone formations grown drop by drop over thousands of years. Show caves, lit and opened with paths, boats and even railways, are especially attractive to film crews, and their halls have served as underground kingdoms, hideouts and alien worlds, giving these places a second life in the imagination of viewers who have never been underground.
The Padirac Cave in southern France is entered through a vast open shaft, explored by Édouard-Alfred Martel in 1889, below which an underground river can be followed by boat. Neptune's Grotto on Sardinia opens at sea level under the cliffs of Capo Caccia, reached either by boat or by a long stairway cut into the rock face. The Castellana Caves in Puglia, discovered in 1938, lead to the Grotta Bianca, a chamber of gleaming white formations.
In Slovenia, Postojna Cave has carried visitors on an underground railway since the nineteenth century and is home to the olm, a blind, pale salamander once taken for a baby dragon. Across the Atlantic, Mammoth Cave in Kentucky is the longest known cave system in the world, a labyrinth of limestone passages stretching for hundreds of miles beneath the forest.

01 Padirac Cave
Gouffre de Padirac
France · 36.7 km from Brive-la-Gaillarde44.858° N 1.750° E
Luc Viatour · CC BY-SA 3.0 The Gouffre de Padirac opens in the Jurassic limestone of the Causse de Gramat, in the Lot department of southwestern France, as a nearly circular shaft about 35 metres across and 103 metres deep. It was once a closed underground chamber; at some unknown moment its roof collapsed, leaving an open well that local people long associated with the devil.
Did you know? In 1948 cave diver Guy de Lavaur explored the Montvalent spring in a wetsuit his wife made by gluing foam rubber onto his old-fashioned bathing costume.
02 Neptune's Grotto
Grotte di Nettuno
Italy · 39.2 km from Sassari40.565° N 8.160° E
Holger Uwe Schmitt · CC BY-SA 4.0 Neptune's Grotto opens at the foot of Capo Caccia, a sheer headland on the coast near Alghero. Its mouth sits barely a metre above the Mediterranean under cliffs about 110 metres high, and that position decides everything about a visit: the cave can only be entered when the sea is calm.
Did you know? For the 1978 film shoot, the crew built a small ship and a Jules Verne-style platform inside the cave, which became a set for about two months.
03 Castellana Caves
Grotte di Castellana
Italy · 35.2 km from Bari40.876° N 17.149° E
Alessandro e Damiano · CC BY 4.0 The Castellana Caves exist on record because of a job that had nothing to do with finding them. In January 1938, the Provincial Tourist Board of Bari brought in Franco Anelli, a speleologist from the Italian Institute of Speleology, simply to assess some already-known local caves for their tourism potential.
Did you know? Between 1953 and 1986 eight films were shot inside the caves.
04 Mammoth Cave
United States · 37.3 km from Bowling Green37.183° N 86.100° W
Daniel Schwen · CC BY-SA 4.0 The most accurate map of Mammoth Cave for nearly forty years was drawn from memory by a man who wasn't free to leave it.
Did you know? Remains of an ancient shark, Saivodus striatus, comparable in size to a modern great white were identified in the cave's limestone in 2020.
05 Postojna Cave
Postojnska jama
Slovenia · 38.4 km from Ljubljana45.783° N 14.204° E
Shesmax · CC BY-SA 4.0 Long before anyone lit a torch in Postojna's deeper chambers, the cave already had a reputation. In 1689 the Slovenian polymath Johann Weikhard von Valvasor recorded local accounts of pale, snake-like creatures that occasionally surfaced in floodwater near the entrance — animals with four small legs, a long tail, and skin the colour of a corpse. People took them for baby dragons.
Did you know? In 1831 the first true cave beetle known to science, the slender-necked Leptodirus, was found here, overturning the belief that caves held no life.
How this list is ranked
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.
