There are four fish sauce factories that allow you to tour their facilities. Three of them are located in Duong Dong town and other is located near An Thoi town.
Phu Quoc fish sauce factory tours consist of visiting warehouses where lager wooden vats holding tons of anchovies are held, looking at the drainage pipe from the gigantic vats to the smaller plastic vats, and then visiting the gift shop. There is no admission charge to visit these factories and a guide is not needed as the process of making the sauce is very simple- put anchovies in a large vat, top off with salt, and then wait for a year.
