Khem Beach sits on Phú Quốc's southeastern coast near An Thới, approximately 25km south of Dương Đông.
The name's origin is debated - one theory traces it to the Khmer word for salt, as the area was historically used for salt production. The more widely believed explanation is simpler: the sand here is so fine, white, and soft that it feels like cream (kem) underfoot, and the name evolved from that sensation.
The beach is a long, gently curving arc of approximately 1.3km of fine white sand with water that runs from pale turquoise in the shallows to deep blue further out, backed by forested hills. Unlike most of Phú Quốc's famous beaches which face west, Khem faces southeast - which means it is sheltered from the southwest winds in summer, but exposed to the northeast monsoon from November to March when conditions deteriorate significantly. Timing the visit correctly is the single most important factor for Khem.
