Cueva del Puerto, Natural cave system in Calasparra, Spain
Cueva del Puerto is a cave system in Calasparra stretching roughly five kilometers underground with limestone formations, natural bridges, and lit pathways throughout its passages. The network features various chambers displaying distinct geological characteristics that become visible during exploration.
The cave shows evidence of past human activity that researchers have documented over time. However, no prehistoric art or Neanderthal remains have been discovered within its passages.
The cave features a section named after a celebrated Spanish architect, with natural rock formations that evoke the distinctive style of that creative vision. Visitors walking through notice how the shapes seem to mirror architectural principles found in famous buildings.
Access is through guided tours offered Wednesday to Sunday, with advance reservations recommended during October through June. Temperatures inside remain constantly cool year-round, so visitors should bring appropriate clothing.
Visitors can choose between standard tours and advanced caving experiences that include abseiling and climbing in specific sections. These more challenging options allow people to explore the cave system in a different way than typical guided walks.
