The cave was discovered by accident when the original owner, Tío Rull, was hunting and noticed the cave's entrance hidden by undergrowth.
It was kept as a private family secret for decades before being opened to the public as a tourist attraction in 1995.
The cave is formed within Jurassic limestone, which is millions of years older than the surrounding cretaceous rock formations in some areas of the region.
The interior is entirely formed by natural karstification processes, with no human excavation performed to enlarge the passageways.
Cueva del Rull is a karst cave system located in the municipality of Vall d'Ebo in the Alicante province of Spain. Discovered in 1919 by José Vicent Mengual, also known as 'Tío Rull', the cave remained a private property until its donation to the local municipality. The site features a 220-meter tourist itinerary accessible via paved walkways and artificial lighting. Geological formations within the cave include diverse stalactites, stalagmites, and flowstones created by centuries of water infiltration. The constant internal temperature remains relatively stable year-round, typically ranging between 18 and 20 degrees Celsius. The cave is managed by the Pego i les Valls tourism department and provides guided tours explaining the geological evolution of the limestone cavern. It is situated in the rugged mountainous terrain of the Marina Alta region, highlighting the area's karst topography.
The main gallery chamber, which features the highest density of illuminated flowstones and large-scale stalactite formations.
Wear non-slip footwear, as the internal walkways can become slippery due to natural moisture and condensation.
Bring a light jacket, as the ambient humidity and constant temperature may feel cool compared to the Mediterranean summer sun.
Book or check availability in advance if visiting during peak holiday seasons or weekends.
Do not attempt to explore beyond the designated paths or light-restricted areas, as the cave system includes deep, unlit vertical drops.
Generally closed on Mondays; always verify operating status before arrival as it may close during severe weather or for routine maintenance.
Do not touch the stalactites or stalagmites, as natural skin oils can permanently damage their growth and appearance.
