Try the super popular “Blue Cave” Diving Plan!
Even first-timers can feel at ease with our full-face mask option!

What’s a Full-Face Mask?
Regular masks cover only your eyes and nose, requiring you to breathe through a separate mouthpiece. But a full-face mask covers your entire face, integrating the breathing system, so you don’t need to hold a mouthpiece in your mouth!
Dive into the magical Blue Cave, where shimmering light creates breathtaking shades of blue.
A certified instructor will guide you safely through the experience.

Before diving, you’ll get a detailed lesson in shallow waters, making it a stress-free experience for beginners.

With four different departure times, you can enjoy the ever-changing shades of blue throughout the day.
After exploring the cave’s glowing blue waters, step outside and swim with colorful tropical fish!
