Technical Suggestions:
To enjoy the perfect experience in the Comino cave system, it is essential to evaluate the most suitable thermal protection according to the season and the type of activity planned. During the summer months, a 3 mm or 5 mm wetsuit offers the right balance between protection and freedom of movement, while for spring or autumn dives it is advisable to choose a 7 mm semi-dry suit to better manage the constant temperature inside the caverns. Those wishing to explore the caves during the colder months will find a drysuit to be the ideal solution for staying dry and enjoying the tranquility of the island. Although the Santa Marija Caves are spacious and illuminated by natural light filtering through the openings, the use of an underwater torch is essential to admire the vivid colors of the sponges and corals covering the walls, as well as to explore the smaller hidden crevices. Given the limited maximum depth, air is the standard choice for most divers, but opting for Nitrox can be an added value for those seeking greater safety and reduced fatigue after repeated dives in the same day between Malta, Gozo and Comino.
