The first stage is a continuous up and down along the coast but the climbs / descents almost never exceed one kilometer in length and the road along is dotted with “attractions” of all kinds.
The things to see and / or do are essentially in the initial part of the route: among the major ones, the initial Olbia-Golfo Aranci road stands out (a beautiful view of the gulf with the Island of Tavolara in the background); the Costa Smeralda with its endless beaches and Porto Cervo and its famous gems (the Pevero Golf, the Capriccioli and Pevero beaches, the Piazzetta, the Porto, the Night Billionaire, etc.); the coastal road Cannigione-Palau and the panoramic point of Palau from which you can see the entire archipelago of La Maddalena. It is a constant delight for the eyes!
Then, after Palau, the road enters the interior among the rocks of Gallura.
