What Is the Roofless Cave?

The Roofless Cave is a dramatic natural formation carved by centuries of wave action into Comino’s rugged coastline near Crystal Lagoon. As its name suggests, the cave has no ceiling, allowing sunlight to pour directly into the turquoise water below. This creates stunning colour contrasts — deep blues, bright aquas, and shimmering reflections on the rock walls.
Unlike enclosed caves, the Roofless Cave feels open and airy, making it ideal for:
  • Viewing from a boat
  • Swimming in calm conditions
  • Photography thanks to natural overhead light
Its location near Crystal Lagoon means it’s often visited as part of a wider cave‑hopping route around Comino.
