"Mui Ne - Fishermen Village and Seaside Resort" Phan Thiet by iblatt

We got from HCMC to Mui-Ne ob the sleeper-bus (used mainly by tourists), which was a good choice, read my tip under "HCMC transportation": http://members.virtualtourist.com/m/d29d6/167100/9/

As for what to do in Mui-Ne: Besides the sea (breezy!) and the water sports, visit the red sand dunes, read my tip under "Phan Thiet things to do":

You can also rent a jeep+guide and go to the white sand dunes, about 20 min from Mui Ne. Definitely go and visit the Mui Ne fishermen village, which is still authentic and unspoiled, better early in the morning when the boats come back from the sea. You can watch my videos:

Another nice place to visit is Fairy Spring, with a short trek in a small canyon with colored sandstone walls. It is easily accessible on foot from the main coast road.

If you want to see an example of Cham temple architecture visit the Po Shanu Cham Towers, halfway between Mui Ne and Phan Thiet. They can be reached by public bus + a short walk, or by bicycle /car / motorbike from Mui-Ne.

In Phan Thiet itself I would recommend the market (very authentic)and the picturesque fishing harbor.
