I think the last sentence is what Baltasound is famous for. Hope this helps.
The excellent main road from the ferry terminus leads north east as far as Baltasound, the scattered village "capital" of Unst. This is considerably less busy than it was a century ago at the height of the herring boom. But it remains home to many of Unst's services, including the leisure centre and school, the main harbour, and the airfield. The Baltasound Hotel is Unst's only hotel (and Britain's most northerly), while the nearby Valhalla Brewery is, in turn, Britain's most northerly brewery.
