There is a coastline in Sardinia that seems designed specifically to put the word “beauty” to the test. It is the Gulf of Orosei, forty kilometers of limestone cliffs dropping sheer into the sea, coves accessible only by sea or on foot, caves carved by water through millennia of erosion, and an hinterland made of canyons, plateaus, and Mediterranean scrub where time seems to have stood still. Viewed from the south, from Ogliastra, this stretch of coast reveals itself in all its majesty: a wild landscape with few equals in the Mediterranean, capable of offering both photographic emotions and true adventures, amid challenging hikes and caves that recount millions of years of geological history.
This article recounts how to explore the Gulf of Orosei starting from Ogliastra, among the most famous coves, the most evocative sea caves, and the coastal trails that allow you to experience this territory at a slow and authentic pace.
A gulf sculpted by limestone
The Gulf of Orosei extends along the east-central coast of Sardinia, between Dorgali/Cala Gonone to the north and Baunei/Santa Maria Navarrese to the south, grazing the territory of Ogliastra. Unlike much of the Sardinian coast, which is dominated by granite, here the absolute protagonist is limestone: white and gray walls plunging vertically into the sea, shaped for millions of years by the action of water and wind, creating an almost lunar landscape that alternates with coves of very white sand nestled between the rocks.
This particular geological composition has given rise to an extraordinary karst system, made of caves, sinkholes, and canyons (the so-called codule, ancient riverbeds descending from the Supramonte plateau to the sea) that make the Gulf of Orosei one of the territories richest in biodiversity and charm in the entire Mediterranean.

The sea caves: masterpieces carved by time
Among the most iconic experiences of the gulf is undoubtedly the visit to the sea caves, authentic natural masterpieces accessible only by sea. The most famous is the Grotta del Bue Marino, one of the most extensive coastal karst systems in Europe, which takes its name from the monk seal that once populated these waters. Inside, imposing halls, underground lakes, and formations of stalactites and stalagmites open up, bearing witness to a past when the sea level was much lower than it is today.
Numerous other smaller cavities dot the coast, some visitable only with expert guides or by kayak, others reachable with traditional boat trips that depart every day in summer from the main landings of the coast. Each cave tells a different story: some preserve archaeological remains of prehistoric use, others are simply theaters of spectacular plays of light, when the sun filters through the transparent water and illuminates the limestone walls with turquoise reflections.

The most beautiful coves of the gulf
Those who explore the Gulf of Orosei for the first time are inevitably captivated by the sequence of coves that follow one another along the coast, each with its own identity.
Cala Goloritzé, declared a natural monument, is probably the most photographed: an arch of very white pebbles dominated by the famous limestone pinnacle that rises for over 140 meters, a coveted destination even for expert climbers. It can be reached with a pleasant walk of about forty minutes from the Golgo plateau.
Cala Mariolu, with its white and pink pebbles smoothed by the sea, is considered by many to be the most beautiful beach in the entire gulf: its waters, with shades ranging from turquoise to deep blue, are among the most photographed in all of Sardinia.
Cala Luna, framed by a pine forest and caves opening into the rock face behind it, combines accessibility (it is also reachable on foot from Cala Fuili via a panoramic path) and a wild charm that has made this beach the location of numerous film productions.
Cala Sisine, more remote and less crowded, offers an evocative contrast between the green of the surrounding vegetation and the dazzling white of the pebbles, in a still uncontaminated setting.
Coastal trekking: the Selvaggio Blu and beyond
For those wishing to experience the Gulf of Orosei with a more active approach, this territory offers some of the most fascinating (and demanding) coastal treks in Europe. The famous Selvaggio Blu, a route of about 45 kilometers crossing the entire gulf among shepherd paths, gullies, and equipped sections, is considered one of the hardest treks in Italy, reserved for expert hikers and generally tackled over multiple days with the help of specialized guides.
For those seeking a more accessible yet equally evocative experience, there are numerous shorter paths allowing the discovery of single stretches of coast: from the descent toward Cala Goloritzé starting from the Golgo plateau, to the routes connecting Cala Fuili to Cala Luna, up to guided excursions along the ancient codule, the canyons descending from the hinterland to the sea, once used by shepherds to lead livestock to coastal pastures.
Along these paths, it is not uncommon to spot the griffon vulture, an imposing raptor that has found one of its last natural refuges in Sardinia on the sheer cliffs of the gulf, along with numerous other species populating this unique ecosystem, suspended between sea and mountain.
How to explore the gulf starting from Ogliastra: the Felix Hotel Galanias Hotel & Retreat
Ogliastra represents the natural gateway to the Gulf of Orosei from the south. From the main landings in the area, such as Santa Maria Navarrese and Arbatax, boat excursions depart daily in season, allowing visitors to reach the most beautiful coves without having to tackle the most demanding trails, alternating swimming stops, visits to sea caves, and on-board lunches featuring local flavors.
Those staying in Ogliastra and wishing to best organize these days between sea and trekking can find an excellent base at the Galanias Hotel & Retreat, immersed in the Ogliastra nature a short distance from the beach of Torre di Barì. The hotel’s strategic position, between Bari Sardo and the main access points to the gulf, makes it convenient to organize both boat trips to the most famous coves and trekking days along the coastal paths, returning in the evening to an environment designed for total relaxation.
It is no coincidence that among the experiences offered by the property is precisely a boat trip to discover the Gulf of Orosei: a guided day discovering the famous Bluezone, among the clearest waters to be admired in Sardinia, designed for those who want to experience the gulf with the convenience of an organization cared for down to the smallest detail, without sacrificing the authenticity of the landscape.
Regaining energy after a day between sea and trails
After a day spent among sea caves, remote coves, and trails overlooking the sea, the body asks for rest and nourishment. The Galanias Hotel & Retreat meets this need with three panoramic pools, including the new Garden Pool immersed in the Mediterranean scrub, and a sea-view yoga center where you can stretch your muscles after a challenging trek.
To refresh oneself, the hotel’s restaurant offers dishes that combine Ogliastra tradition and innovation, made with zero-kilometer products and accompanied by local wines: a perfect way to close the day savoring the very flavors breathed along the coast, from seafood to traditional pastoral dishes that have so deeply marked the history of this gulf.
Practical tips for visiting the Gulf of Orosei
- Best period: from May to October, with July and August being the most crowded; spring and early autumn provide ideal temperatures for trekking.
- How to reach the coves: by sea with organized excursions, or on foot along the trails for those with good physical training; some coves, like Cala Goloritzé, are also reachable with a moderate walk.
- What to bring: trekking shoes for the trails, plenty of water (most coves have no refreshment points), sunscreen, and a swimsuit always ready for swims between one stop and the next.
- Booking in advance: in the summer months, boat excursions and certain restricted-access trails require advance booking.
A territory to be experienced slowly
The Gulf of Orosei is not simply a sequence of postcard beaches: it is a complex ecosystem where geology, pastoral history, and biodiversity intertwine in a landscape that deserves to be explored at a leisurely pace, alternating sea days with inland routes. Viewed from Ogliastra, with the option to choose between guided excursions, challenging treks, or simple boat trips, this stretch of coast offers an authentic and unforgettable experience, capable of leaving a mark long after a vacation ends.
