Alghero is another medieval town, and an extremely interesting one. And that's your destination today. This time you ride westwards on the beautiful coastal road very close to the beautiful and outstretched beaches of the Asinara Gulf. Some kilometers after Porto Torres, the main industrial settlement in the north, you change direction and ride southwards. Before arriving in Alghero, you can take in the magical views offered by the Argentiera and the Porto Conte Regional Park as well as enjoy Capo Caccia, a protected the marine area. This is a stage with a lot to see! Accommodation and dinner in a three star hotel.

On this stage, you’ll experience the special connection between the coastline and mountains in Sardinia. You start from Alghero and ride south to Bosa on one of the most renowned coastal roads on Sardinia. The medieval village here is one of the best preserved on the island. And it’s worth visiting. Enjoy an unforgettable ride through the narrow streets and stop for a quick meal in the heart of this old town. It's simply special. Bosa is the place where you leave the sea behind you. A long climb into the inner mountains of western Sardinia takes you to the historical city of Santu Lussurgiu. A Sardinian traditional dinner awaits us. Accommodation and dinner in a hotel.

This is a real mountain stage. It takes you up to the highest mountain village in Sardinia. After 30 km, you enter the wildest area of Sardinia, called Barbagia. This region is considered the heart of the island, for thousands of years it is here Sardinians took refuge from the invasions of other mediterranean cultures, and an area where tradition and true Sardinian pride live on. You can almost breathe it and you shouldn’t miss it. Here, you ride through very small villages such as Neoneli, famous for the Neoneli’s tenors. This is a male quartet which sings the so called 'Su cantu a tenòre', a style of polyphonic folk singing characteristic of the Barbagia region and today it's a proud member of the UNESCO Intangible Cultural Heritage List. The more you climb, the deeper you get into Sardinian tradition. For instance, you pass through Tonara, a village famous for the production of delicious Torrone nougat. Sardinian nougat is known and loved by many for its delicious taste and top-quality natural ingredients. Fortunately, you will need some extra calories at this stage of the trip. From Tonara we climb up Tascusì pass topping out at 1250m. Your legs will get a well earned respite on the descent before the last hill on the way to Fonni, where we overnight. Accommodation and dinner in an Agriturismo.

Leaving Fonni, we ride southwards and soon we climb over Correboi pass (1250m) and head down a long descent on a quiet and panoramic road that will take us briefly out of the Barbagia region. As we approach to the very wild Ogliastra mountains we bend decidedly towards the coastline and after a lovely up and down section, we take another super long and winding descent with a spectacular view of the southeastern coastline. It is impossible to go quick here: every hairpin calls for a photo! The small town of Talana is a good opportunity for a coffee stop before we turn left and ride towards the SS125, the ancient and iconic road that once was the only connection between south and northeast. Now we have quicker roads to do the job, and the SS125 is a cyclists paradise. You'll discover why. At the end of another long descent on the SS125, we find our destination: the tourist resort of Cala Gonone. Time to take a swim! Accommodation in a four-star hotel.

There's a spectacular way to get out of the Cala Gonone cove, however, as in life, the best things seldom come easy. We need to climb up a steep old road carved into the white limestone. After this tuff start your legs will get some time to recover. We will cross the SS125 again on our way to Galtellì. A stop here is like looking back in time. Galtellì has been awarded the Touring Club Italiano’s orange flag rating for excellence. The streets of the old town centre, its traditions and sensations helped inspire Nobel Prize winning author Grazia Deledda when she wrote her book Canne al Vento. Quite soon after Galtellì we encounter the main climb of the day before passing through two typical Sardinian villages Lula and Orani. Shortly after Orani we will reach the daily destination: Bitti. Dinner and overnight at a four-star hotel.

Hopefully your smartphone's memory card still has some space left, as today will give you plenty of great photo opportunities. You ride to the north to close the Circle. Right from the beginning the scenery is gorgeous: you'll ride along the very large limestone and extraordinarily white range of Monte Albo. Many of the peaks of the limestone bastion are over a thousand metres high; Mediterranean scrub is all around and evergreen. After a long descent, you'll find the valley of the Torpè lake. Contained within a the Tepilora Regional Nature Park: almost eight thousand hectares of unspoilt forests, trails, springs, rivers and ‘dunes’. After some more hilly roads the final descent, of this challenging and unforgettable tour, brings you to Olbia. Overnight at a four-star hotel.
