During our stay in Phu Quoc, we tried a couple of tours around the island. Our hotel (Famiana) used a company called John’s Tours which offered a menu of land and boat/snorkeling tours. Another company called Red River offered similar tours.
My kids weren’t big enough (nor could they swim well enough) to go snorkeling, but even if they had been old enough, I had read (and heard) too many poor reviews of the snorkeling around Phu Quoc island. Based on what I had read, Phu Quoc is not the best place to go snorkeling.
But we still decided to give a couple other tours a try. We went on a Night Squid Fishing Tour and a South and East Island Land Tour.
