My family and I appreciated the free rental of a GoPro so we could get a good video of our kids swimming with the sea turtles. The island of illusion was also beautiful.

I joined this tour with my child. The island was beautiful and the snorkeling was a great experience for my child as we saw sea turtles. However, I gave it 4 stars because I got a little wave-sick.

The coral reefs of Shihsi lagoon were very colorful and beautiful. I was satisfied to see the sea turtles that I was looking for. However, the ship was a bit bumpy that day, so anti-sickness medicine is a must.
