Compared with the waterlogged Mekong Delta, Phu Quoc has very little surface moisture, but there are several springs originating in the hills. The most accessible of these is Suoi Tranh; look for the entrance sign and concrete tree from the Duong Dong–Vong Beach road. From the ticket counter it’s a 10-minute walk through the forest to the falls.  

With displays on Vietnamese medicines, Stone Age tools, a boatful of barnacle-encrusted ceramics, oddly compelling, shell-covered furniture and a small room devoted to the island prison, this private museum is an oddball introduction to Phu Quoc history and culture.  

With picture-perfect white sand, the delightful curve of beautiful Sao Beach bends out alongside a sea of mineral-water clarity just a few kilometres from An Thoi, the main shipping port at the southern tip of the island. There are a couple of beachfront restaurants, where you can settle into a deckchair or partake in watersports. If heading down to Sao Beach by motorbike, fill up with petrol before the trip.
