There’s a stretch of coastline in Sardinia where the sea meets towering red stone — and the view feels almost unreal. In the small town of Arbatax, on the island’s wild eastern coast, nature has created something extraordinary: a cluster of dramatic crimson rock formations rising straight out of the Mediterranean. Locals often describe them as a “cathedral on the sea.” And once you see them, it’s easy to understand why.
The Red Rocks of Arbatax (Rocce Rosse) are among the most striking geological formations in Italy. Sharp spires of deep red porphyry surge upward from crystal-clear turquoise waters, creating a contrast so vivid it barely looks real. At sunrise and sunset, the rocks seem to glow — turning fiery orange and deep scarlet as the light shifts across the sea.
