The White Sand Dunes - Đồi Cát Trắng, more commonly known locally as Bàu Trắng - are located in Hoà Thắng commune, Bắc Bình district, a different and significantly larger dune system from the Red Dunes closer to Mũi Né town (distances cited vary by source: roughly 30-45km from central Mũi Né, or up to 60km from Phan Thiết city, depending on the exact starting point).
The name comes from the Central Vietnamese dialect word 'bàu,' meaning a natural freshwater lake that holds water year-round amid sandy terrain, paired with 'trắng' (white) for the surrounding dunes.
Dunes and Lakes
The dunes stretch across several kilometres of the Bình Thuận coastline, rising to around 40 metres at their highest points, and are flanked by two freshwater lakes - referred to locally as Bàu Trắng and Bàu Sen, though some also call them Bàu Ông and Bàu Bà - that create a landscape combination unique in Vietnam: stark white sand desert beside green freshwater, with the East Sea visible in the distance.
The lakes themselves formed first, as a natural low-lying basin collecting rainwater and groundwater over time, before centuries of strong coastal winds built up the surrounding dunes from wind-blown sand.
What Kind of Site It Is
The site is sometimes called the 'Sahara of Vietnam', a description that overstates the scale but captures the genuine disorientation of standing in an expanse of white sand in a tropical country. It's a popular, well-developed tourist site rather than a remote wilderness - expect a ticket booth, vehicle rental touts, and a real flow of visitors, especially around sunrise.
