This easy and scenic hike & bike loop begins and ends in Palau, offering full immersion in the natural and historical beauty of northern Sardinia. The adventure starts on two wheels, passing through the elegant village of Porto Rafael, beneath the Fortezza di Altura, and on to the old Palau Lighthouse, with sweeping views over the La Maddalena Archipelago and, on clear days, Corsica. From Punta Don Diego, the experience continues on foot along a panoramic loop trail to Cala Trana — a hidden gem framed by granite formations, sandy coves, and Mediterranean scrub. A stop at the Talmone military fort adds a touch of history before the leisurely ride back to Palau. An accessible, rewarding day out for nature lovers, explorers, and photography enthusiasts of all ages.
