The structure extends several stories deep into the mountain, utilizing the natural rock formations as walls and ceilings.
The interior contains a eclectic private collection including antique tools, traditional regional ceramics, and various curiosities.
The cave system maintains a naturally stable temperature year-round due to the thermal mass of the surrounding mountain.
The site acts as a functional tavern, allowing visitors to consume beverages while touring the subterranean passages.
Cuevas del Diablo is an artificial cave museum carved directly into the mountain rock overlooking the Júcar River in Alcalá del Júcar. The site features a series of interconnected tunnels and chambers that function as both a living museum and a bar-cafe. It is known for its peculiar collection of oddities, historical artifacts, and eclectic decor integrated into the natural karst geology. Visitors explore multiple levels of passages that lead to an outdoor terrace offering views of the river canyon. The museum showcases the local tradition of troglodytic dwellings prevalent in this region of Albacete. Its walls are adorned with various objects and collectibles gathered by the owner over several decades.

Wear footwear with good grip as the rock floors can be uneven or slightly slick.
Bring a light jacket even in summer, as the interior temperature is significantly cooler than the outdoor heat.
Visit the upper terrace level to get the best vantage point of the river loop and the village below.
Avoid visiting with large strollers or bulky equipment, as the cave passages are narrow, low-ceilinged, and involve stairs.

Avoid touching the delicate rock surfaces; keep voices low to respect the enclosed acoustics.
