The trip was good, the staffs on the island are friendly, clear water so can see fews turtles. When we there the water so cold so we snorkeling just a shot time but we enjoyed it.

The outer barrier reef is truly beautiful, with vibrant, colorful corals. The reason we chose Silver Swift is its professionalism; it's a godsend for diving enthusiasts. Only after getting up close to the corals do you realize that a true "coral sea" really exists!
Reviews: Cairns Magic Reef Great Barrier Reef 1-day tour with snorkeling, lunch, glass-bottom boat, and semi-submarine

The so-called "Chinese-speaking tour" is actually just a confirmation email sent to your phone by the merchant after you've successfully purchased and paid for the tickets. It lists the activities included in the package. However, there's virtually no Chinese-speaking service throughout the trip; it's essentially like buying two packages and then traveling entirely independently. On the boat and on the Great Barrier Reef platform, those who speak good English can learn more about the activities and have a smoother experience, while those who don't can just go with the flow. The overall experience of this tour wasn't as great as I had imagined beforehand; this varies from person to person because everyone's past experiences and expectations are different.

This was my second time at Phi Loi Island. The last time I went snorkeling alone, I saw a sea turtle. This time, I went to the beach behind the island with my daughter and saw a Napoleon fish. I was incredibly lucky!

Five hours of fun was very satisfying, with enough time to dive and explore the underwater world, and to take photos with a GoPro.
