About the beach
Cala Petra Ruja, within Arzachena (the province of Gallura Nord-Est Sardegna, Sardinia), is a beach on the Tyrrhenian Sea.
The beach faces east (99°). It is most sheltered when the Ponente (W) or Mistral (NW) blows, as it comes from inland; with a Levante (E) or Sirocco (SE) the wind blows from the sea onto the shore and can whip up waves. The orientation is derived from the coastline and is still being verified.
Bathing water quality: excellent (European EEA classification, 2025 season).
