Cala Mariolu: The Cove With the White Pebbles

Round, pale white pebbles instead of sand, and a gradient from turquoise to deep blue, make Cala Mariolu one of the most striking coves in the Golfo di Orosei.

Reachable only by boat or on foot

Cala Mariolu sits on the steep coastline of the Golfo di Orosei and has no road access. Most visitors arrive by boat tour from Cala Gonone or Santa Maria Navarrese. Alternatively, a demanding hiking trail leads there via the Selvaggio Blu route or from Golgo – suitable only for sure-footed, well-prepared hikers.

What makes the cove special

The small, smooth white pebbles give the water an especially bright, almost white tint in the shallows, shifting outward into vivid turquoise and blue. Shade is scarce – bring sun protection and plenty of water.

Practical tip: Most day tours from Cala Gonone combine Cala Mariolu with Cala Luna or Cala Sisine – if you want to see more than one, book a tour with multiple stops rather than a Mariolu-only trip.
The pebbles are slippery and sometimes sharp – water shoes are no exaggeration here.

Swimming & snorkelling

The clear water is great for snorkelling, especially around the rocks at the edges of the cove. Currents and swell can be stronger than at more sheltered beaches, depending on conditions.
