Tips & guidelines

Choose your reef wisely. Outer reef cruises offer the best coral visibility, while the Low Isles are calmer and more beginner-friendly.
Pick your spot on board carefully. Upper decks are ideal for panoramic views and photography, while lower decks provide a smoother, more stable ride.
Opt for morning departures. They typically have calmer seas and better snorkeling conditions.
Dress smart for the day. Arrive in swimwear or easy layers, as changing space onboard can be limited.
Use reef-safe sunscreen. This helps protect marine life and avoids being asked to rinse off before entering the water.
If you are prone to seasickness, choose larger catamarans and sit mid-ship for minimal motion.
Book your cruise in advance. Peak season (June–October) and weekends tend to sell out quickly, especially for outer reef tours.
Plan your snorkeling time. Enter the water early or between activity rushes for clearer visibility and fewer crowds.
Pack light and practical. Bring essentials like a towel, sunglasses, and a water-resistant phone case or dry bag.
Carry an underwater camera. It’s perfect for capturing coral, reef fish, and turtle sightings.
