Cala Petra Ruja

Cala Petra Ruja is a crescent-shaped beach on the Costa Smeralda coast of Arzachena. Its pale sand is bordered by Mediterranean scrub and reddish rocks, whose colour is reflected in the Gallurese name Petra Ruja, or “red stone.”

Why it matters

The cove is part of Arzachena’s coastal landscape, between Liscia Ruja and Razza di Giunco. SardegnaTurismo describes it as a small beach enclosed by scrub, while the municipal tourism portal notes the red-toned rocks behind the shore. The name captures this contrast between pale sand and reddish stone.

What to notice

The shoreline forms an arc between two headlands. The municipal portal describes a main stretch about 340 metres long and a shorter northern beach of roughly 100 metres. Juniper, sea lily and other coastal plants grow behind the sand, while the rocks and low scrub frame the water.

Context and history

Cala Petra Ruja lies on the Arzachena coast, south of Liscia Ruja and north of Razza di Giunco. The surrounding coastal area combines beaches, granite outcrops and Mediterranean vegetation. The Gallurese place-name reflects the red-toned rocks that frame the beach.
