Interesting facts
1

The cave network includes a famous 'chimney' that allows divers to swim vertically through a hole in the seabed.

2

The caves are home to a large population of friendly damselfish that often swim right up to snorkelers and divers.

3

The limestone structure of the caves creates multiple distinct tunnels and caverns, providing diverse routes for underwater exploration.

4

The site is often referred to as 'The Caves' by local diving operators due to its popularity as a training site for beginner cave diving.

5

Sunlight filtering through the ceiling cracks creates a 'cathedral effect' during the middle of the day.

Overview

The Santa Maria Caves are a complex of ten interconnected sea caves located on the northern coast of Comino, Malta. These caves are primarily recognized as a premier scuba diving and snorkeling destination within the Santa Maria Bay area. The sites are characterized by shallow, crystal-clear water and a high density of marine life, including Mediterranean moray eels, octopus, and large schools of damselfish. Divers frequently encounter groupers and occasionally rays inhabiting the sandy bottoms between the cave entrances. The interior of the caves features unique rock formations and light shafts created by the sun penetrating through fissures in the limestone roof. Access to these caves is limited to boat travel, typically originating from Cirkewwa, Malta, or Mgarr, Gozo. The environment is naturally protected, keeping the waters calm even when offshore conditions are windy.

Insider tips

Bring an underwater flashlight to see into the crevices where moray eels and lobsters hide.

Wear a rash guard or light wetsuit even in summer to protect against jellyfish stings often found in these waters.

Ensure your boat operator provides a drop-off at the cave entrance, as swimming from the shore is impractical due to distance.

What to avoid

Avoid attempting to swim to the caves from the main shore of Comino; use a boat to ensure safety and energy conservation.

Good to know

Best accessed between May and October; sea conditions may render the caves inaccessible during winter storms.

Etiquette

Do not touch or disturb marine life; follow 'no-trace' diving principles to protect the delicate limestone environment.
