Route 1A cuts through Binh Thuan Province for 223 kilometres, linking Ho Chi Minh City with the fishing port of Mui Ne in just under five hours by road. The coastal settlement gained prominence in the 17th century as a supply harbour for the Nguyen Lords, its sheltered bay drawing junks laden with rice, salt and dried fish destined for Saigon's markets. By the 1990s, foreign backpackers discovered the windswept shoreline, and within a decade the village had transformed into Vietnam's kitesurfing capital, its consistent northeast monsoon winds between November and March attracting riders from Hanoi to Sydney. Today the district spans 200 square kilometres of contrasting terrain. The red dunes rise 50 metres above sea level along the inland road to Phan Thiet, their iron-oxide sand sculpted by seasonal winds into ridges that shift monthly. Eight kilometres north, the white dunes stretch across 70 hectares of quartz sand, their bleached slopes visible from Highway 706. Between these formations lies the Suoi Tien fairy stream, a shallow watercourse cutting through limestone and clay deposits, exposing sedimentary layers dating back 30 million years to the Oligocene epoch. Geologists identify the region as part of the Song Hong Basin, where ancient riverbeds deposited the mineral-rich sand that now defines the landscape. Mui Ne's fishing harbour operates on tidal schedules unchanged since the French colonial period. Each dawn, approximately 400 coracles—round basket boats woven from bamboo and sealed with resin—ferry crews to offshore trawlers anchored beyond the breakwater. The fleet lands mackerel, squid and anchovy destined for Phan Thiet's fish sauce factories, which produce 30 million litres annually under protected designation. The village market opens at 05:00, its corrugated-iron stalls displaying catches sorted by species and size. Vendors negotiate in the Binh Thuan dialect, a southern variant distinct from Saigon Vietnamese in its vowel length and tonal flattening. The conservation fee of 10,000 VND per visitor applies at the white dune entrance and funds erosion control measures implemented by Bac Binh District authorities. Access hours run from 05:00 to 18:00 daily, though the optimal arrival window falls between 05:00 and 09:00, when oblique sunlight accentuates the dunes' contours and temperatures remain below 28 degrees Celsius. The site's address—Hoa Thang Commune, Bac Binh District—places it 25 kilometres northeast of Mui Ne village proper, requiring private transport or organized tour vehicles along unpaved access roads.
