Highland Boundary Fault Trail

The Highland Boundary Fault was formed 390 million years ago. It traverses Scotland from Arran to Stonehaven, and is most noticeable for the change in topography from the lowlands in the south-east, to the highlands in the north-west. The fault line can be clearly seen at Loch Lomond stretching along Conic Hill, and back across the islands of Inchmurrin, Creinch, Torrinch and Inchcailloch.

The Highland Boundary Fault trail starts from the car park at the David Marshall Lodge Visitor Centre. It combines information on the geology of the area with a walk in the forest and a number of excellent scenic features. Part of the trail follows the route of the old gravity railway that was used to transport limestone extracted from the quarry, located near the top of Lime Craig, via wagons down to the valley floor.

Following the viewpoint marker post, a short detour leads to an outstanding panoramic view from the top of Lime Craig. On a fine day Ben Lomond, Ben Venue and Ben Ledi are clearly visible, while Ben More and Stob Binnein can be seen in the distance. Looking south-west towards Glasgow, the Campsie Fells and Dumgoyne can also be seen.
