Some 60km north of Oristano, BOSA presents an appealing picture of pastel houses huddled around a hilltop castle on the banks of the Temo River. Exploring the mazy lanes of its medieval centre is the chief pleasure here, and it makes a pleasant, if sleepy place to hole up for a few days.
Running parallel to the river, Bosa’s long main street Corso Vittorio Emanuele cuts through Sa Piana, the lower town, site of the cathedral at the Corso’s eastern end, by the old bridge. From Sa Piana, the cobbled lanes of Sa Costa, or upper town, straggle up the hill towards the castle. For a swim, head to Bosa Marina, 2km west, where a crescent of sandy beach is backed by restaurants and bars.
