Arrival in Olbia (OLB), transfer to accommodation in Arzachena. Dinner at 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 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.

This is a real mountain stage. It takes you on a climb 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 in a three-star hotel.

Hope the memory card of your smartphone has still some space left, as this day will give you plenty of great photo opportunities. You ride to the north to seal the Circle and right from the beginning the scenery is gorgeous: you'll ride along the very large limestone - 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 and nowadays a park oasis: almost eight thousand hectares of unspoilt forests, trails, springs, rivers and ‘dunes’ in the territory of Bitti, Lodè, Posada and Torpè. Some more hilly roads will take you to the last - final - descent to Olbia at the end of a challenging and unforgettable trip! Overnight at a four-star hotel.
