Come and see some of the rocks caught up in a major mountain building episode and which caused a national controversy at the end of the 19th century. We will start at Kempie Bay on the eastern shore of Loch Eriboll and then work our way north by car, including a walk out to Heliam and the lighthouse north of Port an Altain.
