Bosa is the prettiest small town on Sardinia's west coast, and it feels like a different island from the resorts. The old centre climbs a hillside above the Temo, the only navigable river in Sardinia, and its tall houses are painted in warm shades of ochre, pink and faded blue. Narrow lanes and stairways lead up toward the Malaspina castle, a medieval fortress on the hilltop whose walls give wide views over the river, the red-tiled roofs and the sea beyond. Down by the water, old tanneries line the riverbank, a reminder of the craft that once drove the town's economy. The journey to Bosa is part of the appeal. The coast road from Alghero twists along high cliffs and over headlands, with views of the sea, rocky bays and, in places, birds of prey wheeling above the rock. A panoramic tour from Alghero usually combines that drive with time to walk through the town, climb toward the castle and linger by the river. Bosa is also known for its local food and drink, including Malvasia wine and traditional handmade textiles and lace. Because the town is lively all year, a visit works well outside the summer season, when the scenery is calmer and the light is soft.
What you see
The old quarter, known as Sa Costa, rises in tiers beneath the castle, and its lanes are best explored on foot. At the foot of the hill, the cathedral and the old bridge frame the riverfront, and the former tannery buildings on the banks are among the few of their kind in Italy.
Walking up to the castle takes some effort, but the reward is a view that takes in the Temo as it curves to the sea and the long beach at Bosa Marina. The town's centre is pleasant to wander, with cafes, shops and small galleries along the main street.
Choosing how to do it
Bosa is about an hour or so by road from Alghero, depending on stops, and the coastal route is slower than it looks on the map. A panoramic tour from Alghero removes the driving and lets you watch the scenery, with a stop or two on the way.
If you have a car, build in time for viewpoints and a relaxed lunch. Local market days and festivals can change the atmosphere of the town, so ask your guide or hotel what is on. Wear comfortable shoes, because the old town is hilly and the cobbles are uneven.
When to go
Spring and autumn give pleasant weather and softer light, and winter days can be bright and quiet, though some seasonal businesses close. In summer the town is lively, but the heat can be strong for the climb to the castle, so go early or late. Pair Bosa with a morning in Alghero and a stop at one of the coastal viewpoints, and bring a camera, because the colour of the houses against the river is the picture you will want to take home.
Good to know
Bosa has a relaxed rhythm, with a long lunch and a late-afternoon passeggiata when locals stroll along the riverfront. Time your visit to catch it, and finish the day with a drink by the water. If you enjoy crafts, look for traditional embroidery and filet lace in small shops, and ask about local pastries, which often use almonds and honey.
