The sea is only the visible half.
On a map, Sardinia's east coast looks like a simple line. On the ground it is a system of limestone walls, dry valleys, plateaus, small plains and hillside villages that can be only a few kilometres apart as the crow flies and still belong to very different landscapes.
In northern Ogliastra the limestone mass of the Supramonte drops towards the Gulf of Orosei. Long stretches have no conventional coastal road: coves such as Cala Goloritzé, Cala Mariolu and Cala Sisine sit below high cliffs and are approached by sea or on foot. Further south, the relief opens. Around Lotzorai, Tortolì, Bari Sardo and Cardedu, flatter coastal land, beaches, lagoons and cultivated plains alternate with mountains behind them.
That closeness of opposites is exactly what makes the area so rewarding by motorcycle. A morning can be spent between rock walls and mountain passes; a short connection later, the road can cross olives, vines and Mediterranean scrub before the day ends at the sea.
Ogliastra: the island within the island
Ogliastra sits between the Gennargentu mountains and the Tyrrhenian Sea. The high ground to the west, deeply cut valleys and a difficult coastline kept the region relatively isolated for centuries. Many historic settlements therefore grew not directly on the shore but slightly inland: closer to water, grazing land and fields, and more protected from a coast that was long a frontier rather than a leisure landscape.
That helps explain why eastern Sardinia does not work like a chain of conventional seaside resorts. Baunei hangs on a slope, Triei sits inland, Jerzu faces vineyards and mountains, Ulassai belongs to the limestone tacchi, while Santa Maria Navarrese and Arbatax are much more maritime. Follow only the shoreline and this structure is easy to miss. Take the side roads and it becomes obvious.

A road that changed isolation
The modern SS125 has a twentieth-century number, but the transport story is older. During the second half of the nineteenth century, work progressed on a continuous road connection along Sardinia's eastern side. The Orosei–Tortolì section was still part of that major infrastructure effort in the 1870s. In 1928 the Strada Statale 125 was formally established as a state road, linking Cagliari with the north of the island along the eastern corridor.
The route was altered repeatedly later on. Newer bypasses and variants were built to speed up everyday traffic and take pressure away from towns. That leaves two very different experiences under the same road number today: fast, modernised sections and older, winding alignments that follow the land closely. Between Baunei, Urzulei, Genna Silana and Dorgali you can still feel why the Orientale Sarda earned such a reputation among travellers and motorcyclists.
The old road is therefore more than a scenic ride. It also tells the story of a region gradually becoming easier to reach, after generations in which terrain and slow connections strongly shaped local life.
Supramonte and the Gulf of Orosei
The Supramonte is not a single peak. It is a broad karst landscape of plateaus, sinkholes, gorges, caves and high limestone walls. From the SS125 it does not appear as one viewpoint and then disappear; it becomes the geology around you for kilometres. Limestone determines the colour of the landscape, the vegetation and the way the road moves.
Genna Silana is one of the places where that upland character is clearest. Paths and roads branch towards Gorropu and the high country of Urzulei and Dorgali. South of it, the road drops again towards Baunei and Ogliastra. The shift between plateau, gorge and distant sea is one reason to allow more time than the kilometre count suggests.
The Tacchi: a different mountain world
South-west of the classic SS125 riding section, the geology changes. Around Ulassai, Osini and Jerzu stand the tacchi: isolated limestone plateaus with steep flanks, like huge tables resting on older rock. The roads here are less famous than Genna Silana, which is precisely why they make such a good second riding day.
Ride from Talana through Gairo, Ulassai and Jerzu and Sardinia stops feeling like a coastal destination. Agriculture, livestock, vineyards and small inland communities become more visible than tourism infrastructure.
A very old cultural landscape
Long before the modern road, this region was inhabited and worked. Ogliastra contains nuraghi, domus de janas, giants' tombs and other prehistoric remains. Many are not isolated inside large archaeological parks; they sit near villages, on plateaus or in agricultural landscapes.
For a traveller, this matters because it changes the way the land is read. Dry-stone walls, old tracks, grazing land and strategic high ground are not just scenery. They belong to a landscape used for thousands of years. If you have an extra day, visiting at least one archaeological site adds more context than simply collecting another viewpoint.
The villages explain the geography
Baunei stands high above the coastal plain and feels like a gateway between sea and Supramonte. Urzulei turns more decisively inland. Triei sits between the famous names and works precisely because of that as a quiet base. Ulassai clings to the tacchi, Jerzu opens towards vineyard country, while Tortolì and Arbatax represent the more connected coastal plain.
For motorcyclists, the lesson is simple: not every rewarding road is a mountain pass. Some of the best transitions are simply the historic links between a village, its grazing land, neighbouring communities and the coast.
Food: why the interior stays on the plate
Visitors who think of Sardinia as an island often expect fish to dominate the table. Ogliastra's historic food tradition is much more closely tied to the interior. Sheep's and goat's cheeses, pane carasau, grilled meats, potatoes, herbs and wine reflect an agricultural and pastoral economy. Culurgiones – pasta parcels commonly filled with potato, cheese and mint – are one of the dishes most strongly associated with the region.
Cannonau is Sardinia's most widely planted red grape, and Jerzu is one of the historic reference areas for it in Ogliastra. Vineyards occupy slopes and terraces where hot days can be followed by much cooler nights. After a day on the bike, food can explain the region more clearly than another scenic stop.
For more detail, Sa Barza has a dedicated long read on Cannonau and Ogliastra cooking.
The sea: not one beach, but several coasts
Between Dorgali and Baunei, high limestone cliffs dominate. Further south the landscape opens. Lotzorai has long beaches and pine areas; Tortolì has the broad, bright coast around Lido di Orrì; Bari Sardo is marked by the Torre di Barì; further south you also find darker pebbles and rougher rocky sections.
This variety is why a fixed base works so well. You do not need to change hotels every day to see a different landscape. A motorcycle ride can begin in the mountains and finish by the sea without becoming a major transfer day.
How to ride the region well
The best plan is not the one with the highest mileage. Three contrasting days reveal more than one giant loop: a day for the SS125 and Supramonte, a day for the inland tacchi, and a flexible day around Baunei, Golgo and the coast. That leaves time for stops, villages and changes in weather.
It is also worth checking navigation before setting off, because the old SS125 and faster modern variants can produce very different rides. In the mountains, shade, animals on the road, changing surfaces and seasonal works matter more than any theoretical average speed.
A good rhythm for four nights
Four nights create a simple framework: arrive, spend one full day on the classic SS125, one day inland, and keep one flexible day for the coast or Golgo. That is enough to experience the region as a connected landscape without packing every evening.
