Cova de sa Gleda

Cova de sa Gleda is a flooded cave system near Manacor on Mallorca, ranked among the most significant cave-diving destinations in Europe.

What makes this cave notable?

Cova de sa Gleda sits within the coastal karst of eastern Mallorca, near Manacor, where limestone bedrock has produced an extensive network of water-filled passages and chambers. Once divers connected it to the neighboring Avenc des Camp des Pou system, surveys recorded a combined length of more than 13.5 kilometers, making it one of the largest known underwater coastal cave systems in Europe. Because of its scale, Cova de sa Gleda is often cited among the handful of largest single-entrance caves of its kind found anywhere in the world.

Why do cave divers travel here?

From the surface, the entrance looks modest, but it opens into a maze of flooded halls and tunnels typical of Mallorca's coastal karst, where brackish groundwater fills passages carved out of the limestone. These systems are known for clear water and dripstone formations that developed before the passages flooded, drawing experienced technical divers who come to explore, survey, and photograph the cave. Diving Cova de sa Gleda is strictly a specialist activity — it requires full cave-diving certification and dedicated equipment, and it is not suitable for recreational divers without that training.

Can visitors see the cave without diving?

Unlike some of Mallorca's other caves that are developed for general sightseeing with walkways and lighting, Cova de sa Gleda is not set up as an above-ground tourist route. Access to its flooded chambers happens almost exclusively through organized cave-diving trips run by specialized diving centers and guides operating in the Manacor area.

How do you get to the Manacor area?

Manacor is one of the larger towns in eastern Mallorca and is well connected by road to the rest of the island, including Palma. The exact entrance location and access conditions — the site sits on private land and typically requires arranging a visit with a diving operator — vary by provider, so it's worth contacting a local cave-diving center on Mallorca directly before planning a trip.
