About Spain Cave Explorer

Our Mission

Spain Cave Explorer was created with a straightforward purpose: to provide reliable, well-researched information about Spain's caves and grottos for travelers, students, geology enthusiasts, and anyone curious about the underground world beneath the Iberian Peninsula.

Spain possesses one of Europe's most diverse collections of cave systems, spanning everything from Paleolithic art galleries in Cantabria to volcanic lava tubes in the Canary Islands, from vast limestone cathedral chambers in Andalusia to the flooded underground rivers of Valencia. Yet comprehensive, up-to-date English-language resources covering these sites have historically been scattered and inconsistent.

Our goal is to consolidate this information into a single, accessible resource that combines geological context, historical background, practical visitor advice, and genuine insight into what makes each cave worth visiting.

Our Approach

Every guide on this site is built on careful research drawing from geological surveys, published academic studies, official tourism resources, and firsthand accounts. We consult sources including the Instituto Geologico y Minero de Espana (IGME), UNESCO World Heritage records, regional tourism boards, and peer-reviewed speleological literature.

We aim to present information that is scientifically accurate without being dry or inaccessible. Our content is written for curious travelers and armchair explorers alike, balancing factual rigor with narrative engagement.

Visitor information, including opening hours, access conditions, and ticket details, is verified against official sources, but we always recommend confirming current details before your visit as conditions can change.

Editorial Independence

Spain Cave Explorer operates independently and is not affiliated with any tourism operator, accommodation provider, or commercial entity. Our recommendations are based purely on the quality, significance, and accessibility of each site. We do not accept payment for coverage, and our editorial decisions are not influenced by commercial considerations.
