How This Site Started

My first experience inside a Spanish cave was at the Cuevas del Drach in Mallorca, during a family holiday when I was twelve years old. Sitting in the dark above Lake Martel, listening to musicians play from boats, I felt a kind of awe that stuck with me for years. It was the realization that beneath the landscape we walk on every day, there are entire worlds shaped by forces operating on timescales we can barely comprehend.

I returned to caves throughout my twenties, first as a casual visitor, then as an amateur caver, and eventually as someone who wanted to share what I was discovering. This site grew out of notes I kept during trips to cave systems across the Iberian Peninsula. It is not an academic resource (there are excellent ones out there, and I link to them), but rather a practical guide informed by personal visits and a genuine fascination with the subject.

What I Try to Do Here

The goal is straightforward: provide accurate, useful information for people who want to visit caves in Spain. That means honest assessments of what each site offers, practical details like opening hours and accessibility, and enough geological and historical background to give your visit context without turning it into a lecture.

I try to write as if I were advising a friend who asked "which caves in Spain are actually worth visiting?" The answer depends on what interests you, whether that is the raw spectacle of massive underground chambers, the quiet contemplation of 15,000-year-old art, or the scientific story written in layers of mineral deposits.

About the Content

All articles are based on personal visits and supplemented by published research from institutions including the Instituto Geologico y Minero de Espana, the University of Cantabria's geology department, and various UNESCO publications. Images are sourced from Wikimedia Commons under Creative Commons licenses, with attribution provided for each.

Cave conditions, schedules, and access policies change over time. I update articles regularly, and the date of the most recent revision is noted on each page. If you notice something that has changed or find an error, please get in touch.

A Note on Conservation

Caves are fragile environments. The formations you see inside them took thousands or millions of years to develop, and they can be damaged in seconds by a careless touch. When visiting any cave, please follow all posted guidelines, stay on marked paths, and resist the temptation to touch formations. The oils from human skin can permanently discolor mineral deposits and halt their growth.

Several of Spain's most important caves have been closed or severely restricted due to damage caused by tourism. The lesson is clear: if we want these places to remain accessible, we need to treat them with the respect they deserve.
