We took the snorkeling tour in Phu Quoc with the tour guide Tuan Anh. The experience was exceptional. The tour guide was very skilled in snorkeling, bi lingual, and... read more provided a nice training of how to properly snorkel. In addition, the actual snorkeling was great. We spent about 2 full hours in the water at two different locations with bright blue water that allowed you to see 6-8 meters down. After the snorkeling is completed, you relax with a cocktail and watch the sunset. I have taken a lot of guided tours in South East Asia and this was by far the best activity I have ever done. I very strongly recommend this to anyone looking for a day activity in Phu Quoc.
