Shallow boat-access Comino cave with easy overhead scenery.
Alex's Cave is a short shallow cave route off Comino's Crystal Lagoon, entered from a boat and followed through a bright tunnel system with seagrass, pale rock walls, and easy overhead navigation for divers already comfortable with basic cavern discipline. The site is not deep or technically complex, but it still rewards good buoyancy and light use because the appeal comes from the cave geometry, filtered blue light, and small cave life such as bream, morays, congers, octopus, and occasional nudibranchs.

Key Hazards
Safety Notes
Although Alex's Cave is shallow and often treated as an easy introduction to overhead scenery, it is still a cave-style route. Divers should carry a light, hold position carefully over the floor, and avoid entering if surge or visibility make the tunnel uncomfortable.
Access Restrictions
Usually accessed by dive boat inside Crystal Lagoon; direct shore logistics are awkward and not the normal way operators run the site.
Community notes to help plan your visit.
Scuba Diving
A straightforward cave dive route with depths around 8–16 m and an estimated length of 40 m.
Freediving
The cave is not generally marketed as a freedive route because the site is run as a scuba cavern with overhead sections and boat access.
Snorkeling
Crystal Lagoon is popular for snorkeling, but Alex's Cave itself is an overhead scuba route rather than a casual snorkel-through.
