Berriedale
Berriedale is a small estate village on the north east coast of Caithness, Scotland, on the A9 roadway between Helmsdale and also Lybster, close to the border between Caithness and Sutherland. It is sheltered from the North Sea. The village has a parish church in the Church of Scotland. Simply south of Berriedale, on the way to the north, the A9 passes the Berriedale Braes, a steep decrease in the landscape (brae is a Scots word for hill, a borrowing of the Scottish Gaelic bràighe). The road drops down outstanding (13% over 1,3 km) to bridge a river, prior to increasing once again (13% over 1,3 km), with a variety of sharp bends in the road-- although some of the barrette bends as well as other close-by gradients have been relieved in recent times. The impracticality (and expense) of linking the Berriedale Braes prevented the structure of the Inverness-Wick Far North Line along the eastern coastline of Caithness; instead the railway runs inland through the Flow Country. Berriedale lies at the end of the 8th stage of the coastal John o' Groats Path.
