Dive Site Overview

Approaching Comino Island's Blue Lagoon, visitors are greeted by its striking turquoise waters and pristine white sandy seabed. For certified divers, however, the compelling underwater experiences largely extend beyond the lagoon's immediate, shallow 3 m (10 ft) basin.

Alex's Cave, an intricate system within a substantial islet south of the lagoon, emerges as a primary destination, welcoming divers across all skill levels. This cave system is characterized by its series of interconnecting chambers, including a remarkable section where divers can surface into a fresh air pocket, creating a distinct and memorable exploration. Accessing Comino's diverse dive sites, including the areas near the Blue Lagoon, is exclusively boat-dependent, often requiring a brief 10-minute journey from neighboring dive centers.

This location serves as an excellent starting point for various aquatic adventures, encompassing not just shallow reef environments but also more demanding dives to deeper wrecks and other intricate cave formations such as the Santa Maria caves. Inside Alex's Cave, conditions are typically calm, providing a sheltered environment even when surface conditions are less settled, ensuring consistently good visibility.
