Dive Experience & Conditions

Dive Difficulty & Safety Guidelines
For divers considering the Santa Marija Caves, an Open Water Diver certification, allowing dives to 18 m (59 ft), is the minimum required qualification. This site is suitable for less experienced divers due to its generally calm conditions and relatively shallow depths within the cave structures. Access to the caves is exclusively by boat, typically arranged through local dive centers from Malta or Gozo.
While the caves are largely protected from strong currents, it's always prudent for divers to check local weather and sea conditions before a dive, as patterns can shift. Adhering to responsible diving practices, such as maintaining neutral buoyancy and avoiding contact with delicate formations, is essential to preserve the cave's natural state.
