Bosa is the most BEAUTIFUL small town in Sardinia — and the least visited. Pastel houses (pink, ochre, blue, green) climb from the River Temo to the Castello Malaspina (12th century) on the hill above. The Temo is the ONLY navigable river in Sardinia — traditional boats (gozzi) are moored along the quay, fishermen mend nets, the riverbank has tanneries converted to restaurants. The Malvasia di Bosa DOC is an amber dessert wine aged in chestnut barrels IN THE ATTICS of the old town — the sun heats the barrels through the roof tiles, a process called “oxidative aging” that gives the wine its distinctive amber-caramel character. Bosa is Sardinia without filter.
Sa Costa (the old quarter): Climb the narrow streets from the river to the castle — every house painted a different pastel shade, flower pots on stairs, cats in doorways. Castello Malaspina (12th century): Ghibelline castle on the hilltop — views of the river, the town, the coast, the limestone plateau behind. Inside the chapel: 14th-century Catalano-Aragonese frescoes. €4. The Temo river: Walk the Lungotemo — the quay with moored boats, the old tanneries (Sa Costa e Sas Conzas — now a museum of leather tanning, €3), the footbridge.
Bosa Marina (2km west): Sandy beach, the tower (Torre Aragonese), calm water. The coast south of Bosa: Wild, unpaved roads to coves — Cala’e Moros, Compoltitu. Griffon vultures: The cliffs between Bosa and Alghero hold one of the last GRIFFON VULTURE colonies in Italy — visible soaring above the coast road.
From Alghero: 45 min (the coast road is one of the most beautiful drives in Sardinia). From Cagliari: 2.5h. No train — car essential. Stay 2 nights: Evening on the river with Malvasia. Morning on the beach. Afternoon in Sa Costa. Eat: Sa Pischedda (Via Roma 6 — river fish, Bosa’s traditional bottarga). Sardinia →
