I got a bus to Miu Ne today which is about 3-4 hours north of Saigon on the coast. It is a famous wind and kite surfing spot in Vietnam, but now it is out of season and there is very little wind.
The beach is fairly nice and there are plenty of both cheap and expensive places to stay. One problem I have is that I always compare the beaches and the places I stayed at in Thailand. It is pretty quiet here so I am thinking of moving on fairly quickly to Dalat and then on to Nah Trang.
