The caves are carved into one of the largest gypsum karst landscapes in the world.
The gypsum rock formations here are remarkably soluble compared to the more common limestone karst caves.
The site hosts a unique subterranean micro-fauna that has adapted to the high-sulfate, low-light environment.
The caves were formed by the action of the Aguas River cutting through a massive gypsum deposit.
The Sorbas gypsum basin was formed approximately 6 million years ago during the drying of the Mediterranean Sea.
Some sections of the cave system contain rare selenite crystals that can grow to significant sizes.
Cuevas de Sorbas is a vast underground karst system located in the Yesos de Sorbas Natural Area in Almería, Spain. The site is characterized by an extensive network of gypsum caves formed by the dissolution of sulfate rock. Visitors can access various routes ranging from basic tourist walks to more technical caving expeditions. The subterranean environment features a high density of crystalline formations, including stalactites, stalagmites, and gypsum needles. These caves are part of a protected landscape that encompasses the Barranco del Infierno ravine. The area contains thousands of cavities, though only specific sections are open to the public to preserve the delicate geological equilibrium. The geological history of this area dates back to the Messinian salinity crisis. Guided tours are mandatory due to the complexity and fragile nature of the karst system. The surrounding karst desert landscape offers a distinct arid aesthetic that contrasts with the humid underground cave conditions.

Book your guided tour well in advance as group sizes are strictly limited to protect the cave environment.
Bring a light jacket, as temperatures inside the caves remain constant and are typically cooler than the surface desert heat.
Use the provided safety gear, including helmets and lamps, throughout the entirety of the guided tour.
Attempting to enter the cave system without a professional guide or straying from marked paths.
Open year-round but subject to weather-related closures if heavy rainfall increases flood risk within the tunnels.
Closed-toe sturdy footwear with good grip is mandatory; touching cave formations is strictly prohibited to prevent oil transfer and damage.
