Cù Mi Beach lies along the coast of Tân Thắng commune, Hàm Tân district, in southern Bình Thuận, in the gap between the heavily developed Mũi Né resort corridor to the north and the newer development zone around Hồ Tràm and Bình Châu to the south. The beach serves primarily as a working fishing community shoreline - colorful wooden boats are hauled up on the sand, nets are spread for drying, and the rhythms of the beach are determined by tides and fishing schedules rather than tourist seasons.
The landscape behind the beach is distinctive: rolling sand dunes interspersed with grassy wetland ponds, cattle grazing lazily on the sunlit hills, and sparse dương (casuarina) trees that, despite their thin coverage, cast surprisingly wide, useful patches of shade thanks to their broad canopies.
Development is minimal: a scattering of small food stalls sell basics like swim rings, water, and grilled seafood, alongside a few small guesthouses and restaurants in the nearby town, but there's no resort infrastructure on the beachfront itself. Tourist activity is minimal here - it's mostly local residents who come to swim, early morning and late afternoon, rather than a beach that sees organised tourism.
The sand is a mix of pale and golden tones, the water reasonably clear in the dry season, and the backdrop of low coastal hills adds definition to what is otherwise a flat coastline.
