Why Dive or Snorkel at the Blue Cave?

The Blue Cave is a shallow cavern, approximately 5 meters (15 feet) deep, making it accessible and safe for beginners. The sunlight entering the cave creates a stunning blue glow that gives the site its name.

During peak season and midday hours, the Blue Cave can become extremely crowded. For the best experience, we strongly recommend early morning trips (7:30 AM), when the cave is quieter and its natural beauty can be fully appreciated.
