The name 'Cova de les Calaveres' translates to 'Cave of the Skulls' in Valencian.
Human presence in the cave dates back to the Middle Palaeolithic period, approximately 50,000 years ago.
The cave extends for about 400 meters, but only the first section is fully adapted for tourism.
It served as a refuge for local inhabitants during the flood events of the 17th century.
The cave's ecosystem is home to several species of endemic cave-dwelling insects and bats.
The rock formations are composed of Jurassic limestone, which is highly porous and susceptible to karst erosion.
Excavations have uncovered remains of extinct animals such as the cave bear and rhinoceros, indicating past environmental changes.
Cova de les Calaveres is a 400-meter-long subterranean cave system located in the limestone foothills of the Sierra de Segaria in Alicante. The site is named for the 17th-century discovery of human skulls and remains belonging to inhabitants who sought refuge during a flood. Archaeological excavations have recovered remnants of Palaeolithic and Neolithic settlements, including flint tools and ceramics. The interior features geological formations such as stalactites and stalagmites created by water filtration over millennia. It served as a shelter for humans dating back to the Middle Palaeolithic period. The cave entrance is situated at the base of the mountain, leading into a series of galleries accessible to the public. Lighting has been installed throughout the path to highlight the geological structures. The site remains a significant geological and historical landmark in the Marina Alta region.
The illuminated wide-angle gallery near the entrance offers the best perspective of the large geological formations.
Wear shoes with good grip, as the internal pathways can be damp and slippery.
Bring a light jacket as the cave maintains a cool, constant temperature regardless of the external weather.
Take your time in the initial gallery to read the historical placards explaining the archaeological finds.
Avoid visiting immediately after heavy rainfall, as the cave floor may become excessively muddy or flooded.
Do not touch the stalactites or stalagmites, as natural oils from human skin stop their growth; stay within marked paths.
