Cave temperatures remain between 12 and 21 degrees Celsius year-round. Bring a warm layer even in summer, and wear sturdy, non-slip footwear. Floors can be damp and uneven in many caves.
Popular caves like Cuevas del Drach and Gruta de las Maravillas can sell out, especially during summer months and weekends. Online booking often provides discounts and guarantees your preferred time slot.
Weather conditions outside do not affect cave visits. Underground temperatures and conditions remain constant, making caves an excellent activity regardless of the forecast. Ideal for those unpredictable travel days.
Never touch formations as oils from skin can damage stalactites and stalagmites that took thousands of years to form. Follow guide instructions and stay on marked paths throughout your visit.
Accessibility varies considerably between caves. El Soplao offers fully wheelchair-accessible tours, while Gruta de las Maravillas is not suitable for visitors with reduced mobility. Always verify before your visit.
Photography policies differ by cave. Flash photography is generally prohibited everywhere to protect formations and wildlife. Some caves like Gruta de las Maravillas ban all photography inside the chambers.
Spain's geological diversity has created an extraordinary variety of underground landscapes found nowhere else in Europe.
With thousands of documented caves stretching from the Cantabrian coast to the Canary Islands, Spain offers an unparalleled range of subterranean experiences. The country's varied geology, encompassing limestone karst, marble formations, gypsum caves, and volcanic lava tubes, has produced underground landscapes of exceptional beauty and scientific significance.
Northern Spain's Cantabrian region is home to 18 UNESCO-listed caves containing some of the finest examples of prehistoric art ever discovered. The paintings at Altamira, El Castillo, and Tito Bustillo date back more than 35,000 years, offering an extraordinary window into the creative minds of our earliest ancestors.
Beyond the north, Andalusia's cave systems reveal vast underground rivers and crystal-clear lakes, while Mallorca's Dragon Caves draw visitors with their spectacular formations and unique concert experiences. Whether you seek geological wonder, historical insight, or simply an unforgettable adventure, Spain's caves deliver on every front.
