The Brough of Birsay is found on the north west coast of Mainland Orkney.
Cross the causeway at low tide to this tidal island where you will find the remains of both Pictish and Norse settlements, including St Peter's Kirk.
A walk to the far side of the Brough brings you to the lighthouse and cliff face. This is a good place for watching migratory birds and a chance to see puffins (May - July). Keep your eyes peeled for whales off the shore and for the popular groatie buckies (cowrie shells). Tide times can be given from one of Orkney’s Visitor Information Centres.
