Arrival in Olbia, transfer to accommodation in Arzachena. Dinner at a four star hotel.

From Costa Smeralda, riding along the hills of northern Sardinia, and passing through the famous landscapes of the Aggius valley, you come to the medieval town of Castelsardo. This is a very well preserved historical city, thanks to the fact that it’s perched atop a promontory high above the sea that has protected it from attacks and destruction over the centuries. Today, Castelsardo is a well-known tourist destination with all the services imaginable available for you. There’s a marina and beautiful beaches and small inlets perfect for a pleasant summer holiday. But rituals and traditions such as the famous Festa di Lunissanti mark the everyday life of the town, characterized by the industrious work of basket-weavers, fishermen, and farmers. You’ll love it! Accommodation and dinner in a four-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.

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.
