Cave temperatures typically range from 14-18 degrees Celsius year-round. Bring a light jacket even in summer, and wear sturdy, non-slip footwear for uneven surfaces.
Never touch cave formations as oils from skin can halt thousands of years of mineral growth. Stay on marked paths and follow guide instructions to preserve these fragile ecosystems.
Flash photography is prohibited in most caves to protect formations and prehistoric art. Many locations permit non-flash photography, but always verify at the entrance.
