In the municipality of Arzachena, in the province of Gallura Nord-Est Sardegna (Sardinia), Lu Postu is a sandy beach on the Tyrrhenian Sea.
Orientation: north (358°). An offshore wind, i.e. the Ostro (S) or Sirocco (SE), keeps it calm; the Tramontane (N) or Mistral (NW) hits it from the sea and can raise waves.
Sandy bottom: easy entry into the water, just take care when the sea is rough.
Bathing water rated excellent by the EEA (2025 season).
