At the other side of the Braighe you will see Knock Community shop (Buth an Rudh), keep on the main road. After a short distance you will see a road sign for Knock/Swordale, take this turning to the right (single track road), then take the first road to the right. Seascape Cottage is the second house on the right.
Leaving the airport at Stornoway you will come to a roundabout. Drive straight on until the T-junction. At the junction turn left onto the Briaghe, then follow the directions as above.
