There are beaches you visit and others you remember for years. Cala Mariolu definitely falls into the second group.
A natural amphitheatre of white rock and crystal-clear water, the sea here shifts colour throughout the day, from deep emerald to intense turquoise. Reached either by boat or along panoramic trails in the Supramonte mountains, this wild bay is often ranked among the most beautiful in Sardinia.
Where is Cala Mariolu and what makes it unique?
Cala Mariolu lies on the Gulf of Orosei, in the Baunei area, along a rugged coastline that alternates between sheer white cliffs and tiny hidden coves. The water shimmers in shades of turquoise and emerald, while the shoreline is covered in pale and pink, rounded pebbles known locally as pulci di neve (“snow fleas”).
The seabed is shallow close to shore, then drops away, creating superb conditions for snorkellers and divers, with exceptional visibility that amplifies every flash of colour.
All around, the steep, dramatic landscape takes centre stage, with occasional sightings of dolphins out at sea and peregrine falcons circling overhead. Even the name hints at its history: mariuolu recalls the monk seals that once “stole” the fishermen’s catch in this area.
How to get there: by sea is easier
Looking at photos of Cala Mariolu, the first doubt tends to be a practical one: how do you actually reach a beach wedged between limestone cliffs and glass-clear water? In most cases, the simplest option is by sea.
Boat services run from nearby ports, and in high season several operators offer boat trips with scheduled stops that include Cala Mariolu.
Another option is to rent a dinghy and manage your own timings, always keeping a close eye on the weather and sea conditions.
- From the north: departures from the port of Cala Gonone, with frequent services in summer.
- From the south: boats leave from Santa Maria Navarrese and Arbatax, both handy bases for exploring the central and southern Gulf of Orosei.
- Organised tours: shared motorboats with fixed itineraries that usually include Cala Mariolu, ideal if you prefer everything planned in advance.
- Dinghy hire: offers more freedom over stops and timings, but requires basic experience of coastal navigation and attention to sea conditions.
Getting there on foot: trekking from Golgo
Walkers keen to earn their swim can reach Cala Mariolu on foot along a hiking trail starting from the Golgo Plateau. The route is around 6.5 kilometres one way, mainly over rocky terrain, and calls for steady footing and some experience with changes in altitude.
The outward leg drops steadily down towards the sea, while the return involves around 600 metres of ascent. The scenery is harsh and spectacular, with viewpoints that open out over the coastline before you finally descend to the beach.
