Practical Tips for Cave Visitors
Make the most of your underground adventures with these helpful recommendations gathered from experienced cave explorers.
Wear Appropriate Footwear
Cave floors can be wet and slippery. Choose closed-toe shoes with good grip. Avoid sandals and heels as they are typically not permitted inside guided caves.
Bring a Light Layer
Cave temperatures typically range between 14 to 20 degrees Celsius year-round, regardless of the outside weather. A light jacket or sweater is recommended even during summer months.
Book Tickets in Advance
Popular caves like Cuevas del Drach and Nerja frequently sell out during peak season (June through September). Booking online at least a week ahead ensures you get your preferred time slot.
Respect the Environment
Never touch formations inside caves, as natural oils from skin can stop stalactite and stalagmite growth that took thousands of years to develop. Stay on marked paths at all times.
Consider Off-Peak Visits
Visiting during early morning or late afternoon, or during shoulder season (April-May, October), means smaller crowds and a more intimate experience of these natural wonders.
