Protecting Mallorca's Underground Ecosystems

Mallorca's limestone landscapes contain fragile karst ecosystems that house rare endemic species and ancient mineral structures. While geological tourism supports the local economy, certain cave systems are too delicate for commercial visits. To protect these natural resources, the Balearic Government and scientific associations have classified several systems as strictly restricted.

1. Cova de la Gleda (Manacor)

Located near Manacor, Cova de la Gleda is nearly 11,000 meters long, making it the largest submerged cave system on the European continent. The system contains massive freshwater and saltwater galleries. This system is strictly closed to the general public, reserved exclusively for advanced scientific research and speleological mapping. Trespassing is dangerous and illegal.

2. Coves des Pas de Vallgornera (Llucmajor)

This extensive cave system in Llucmajor is environmentally protected due to its fragile mineral structures and unique endemic fauna. It has over 74 kilometers of mapped galleries. The system is closed to standard tourism to prevent damage to its mineral deposits. It is among the caves you cannot enter into, as access is limited to research teams with official permits from the Environment Department.
