3 Best Sights in Orkney and Shetland Islands, Scotland

An Iron Age tower built between 500 BC and 200 BC, the Broch of Gurness stands more than 10 feet high and is surrounded by stone huts, indicating that this was a village. The tower's foundations and dimensions suggest that it was one of the biggest brochs in Scotland, and the remains of the surrounding houses are well preserved.

A Romanesque church can be seen at the Brough of Birsay, a tidal island with the remains of an early Pictish and then Norse settlement. (Brough is another word for "fort".) The collection of roofless stone structures on the tiny island, close to Birsay, is accessible only at low tide by means of a concrete path that winds across the seaweed-strewn bay. The path is slippery, so boots are essential. To ensure you won't be swept away, check the tides with the tourism office in Kirkwall or Stromness before setting out. The cliffs at the far side of the island are stunning but be very careful as you look for puffins.

The Royal Society for the Protection of Birds tends the remote Marwick Head Nature Reserve, where in spring and summer the cliffs are draped in wildflowers such as campion and thrift, and resound with thousands of nesting seabirds including cormorants, kittiwakes, and guillemots. The Kitchener Memorial, recalling the 1916 sinking of the cruiser HMS Hampshire with Lord Kitchener aboard, sits atop a cliff. Access to the reserve, which is unstaffed, is along a path north from Marwick Bay.
