Fish Sauce Factories
Local tours often stop in at one of the pungent fish sauce factories, several of which are concentrated along the river in Duong Dong Town. It's possible to visit without an organized tour, although an English-speaking guide may not be available and without explanation, you're just looking at a hot, odorous shed full of giant wooden vats. Try Khai Hoan on Hung Vuong Street ( 0297/384–8555).
Airlines that fly out of Phu Quoc do not allow fish sauce on board due to risk of breakage, but it is usually possible to buy it at the airport departure lounge.
