Admiring the massive rock of Pan di Zucchero at sunset makes the sunlight even more incredible as, in every shade of yellow and orange, it outlines the shape of the limestone rock. You will be able to reach the natural monument symbolizing Masua, a coastal district of Iglesias, by dinghy or by boat, although it is not an easy endeavour. Climbing enthusiasts, with equipment and the support of specialized staff, can climb to the peak, which is 133 metres high. From above, you can see other nearby rocks of S'Agusteri and del Morto and the sea stack of Punta de Is Cicalas.

The islet of Pan di Zucchero, which gets its name from its resemblance to Pão de Açúcardi in Rio de Janeiro, is characterized by its light colour and by its surface consisting of flat ridges. Inside, it is perforated by two large arches that create karst phenomena with tunnels, one of which you can travel throughin a small boat. In front, you will see the sea stacks of Porto Flavia, where the tunnel of an evocative twentieth-century mine, carved in the reef, opens up. From here, minerals were loaded directly onto the merchant ships. At the foot of the mine, there is the cave of the Soffione (meaning fumarole), so-called because of the effect generated by the waves of the sea that meander into its cavity and are 'bounced' making large splashes.

In the beautiful cove of Masua, in front of the sea stacks, there is a large beach equipped with all necessary services, including boat trips and trekking. Its seabed is sand, mixed with stones and a few rocks, especially near the sea.
