A couple pics from my recent trip to Phu Quoc Island which, inexplicably, is part of VN.
Notice it's just off the coast of Cambodia. How Phu Quoc came to be in Vietnamese hands is somewhat confusing, so I'll just leave it at that.
People go for the beach.
Lots of wonderful natural sites on Phu Quoc but public access to these places is largely restricted. Here's a little river.
