The capital of Binh Thuan province, Phan Thiet, is a small-but-thriving Vietnamese city, and would be a decent destination for tourists in its own right, but for one small problem: it's a stone's throw from Mui Ne, and there's no good reason for the foreign tourist to dally here when a prime beach-town is beckoning just over the horizon.
That being the case, Phan Thiet sees very few foreign faces, save those visiting on a day trip from Mui Ne or belting through on an Open Tour minibus.
