The cave system extends for approximately 4,000 meters, though only a portion is open for guided tourist access.
It is situated at an elevation of 600 meters above sea level within the Pre-Betic geological zone.
Archaeological findings include ceramic remains and tools belonging to the Argaric culture of the Bronze Age.
The cave is formed in Jurassic limestone, which is characterized by its high susceptibility to karstic dissolution.
The interior temperature remains constant at approximately 17 degrees Celsius throughout the year regardless of external weather.
The formation of the cave's eccentric structures is attributed to the presence of varied mineral compositions in the infiltrating water.
Cueva del Puerto is a subterranean limestone cavern system located within the Sierra del Puerto mountain range near Calasparra, Murcia. The cave features a complex network of galleries adorned with diverse speleothems, including stalactites, stalagmites, and eccentric formations. Geologically, the site is recognized for its stable internal microclimate, maintaining a constant temperature year-round. It is accessible to the public via guided tours that traverse the most significant chambers of the 4-kilometer-long cave system. The cave holds archaeological significance, showing evidence of human usage dating back to the Bronze Age. The interior is equipped with artificial lighting designed to minimize impact on the cave's natural environment. It serves as a primary site for speleological study in the region due to its distinct karst morphology.
The 'Sala de las Cascadas' (Waterfall Chamber) offers the most dramatic geological formations for photography.
Wear comfortable, non-slip footwear with good grip as the cave floor can be damp or uneven.
Bring a light jacket as the cave's constant temperature may feel cool compared to the external summer heat of Murcia.
Book your guided tour in advance online, as entry is strictly controlled and group sizes are limited.
Do not attempt to explore beyond the marked path or the guide's instructions, as the cave system is complex and hazardous.
The cave is typically closed on Mondays; advanced booking is mandatory for all visitors.
Do not touch the cave formations, as oils from human skin can disrupt their growth; flash photography is often prohibited to protect cave-dwelling fauna.
