To The entire team of Silversonic - Thank you. They were very friendly, patient and made all of us very comfortable. Gordon was our dive instructor and he was extremely patient and understanding as it was our first dives. I was able to do two intro dives and by the second dive, I was able to move around myself and he was closely watching us to ensure we were absolutely safe. The food was great and plenty. There was plenty of cookies/biscuits and coffee/tea before we left and again later in the afternoon. The photographer ensured we all got our time in the Reef captured. While the sea was rough and bumpy on the way back, the skipper ensure we all got back safely ! Kudos to him ! The crew also offered sea sickness tablets which we bought and glad we did. All in all, a great day and crew. Highly recommended!

The day was beautiful, perfect for the reef tour! A special shoutout to Gordon, what an amazing person! He took the time to show me around as I was a first-timer and gave me the confidence to try snorkeling by myself. And guess what? I saw a turtle, it was as close as arm’s length! I couldn’t believe I was able to do it on my own. Thank you, Gordon—you’re amazing! A special mention to the staff, thank you for looking after all of us. The food was great and you kept checking on us to make sure we’re ok!! Thank you for your hospitality guys!!

Absolutely once in a lifetime experience! We did the 2 intro dives and our instructor Hannah was fantastic, especially in spending extra time with those who needed more support. A great crew overall who have the entire experience set up as a well oiled machine. So worth it

Magical day on the reef. The crew were professional and lots of fun. Visited 3 amazing reefs and a generous amount of time at each. Would recommend this tour operator.
