From Kirriemuir, the B955 road takes you through open farming country. At Dykehead, turn left for Glen Prosen; or alternatively, carry straight on for Glen Clova and Glen Doll.
The glens' upper road forms a loop: So you can admire the view from one side of the valley and return by the other side of the river.
Glen Doll lies at the head of Glen Clova - take the narrow road adjacent to the Clova Hotel, which will lead you into the heart of the mountains. The end of the glens is dominated by the Cairngorms.
On your return southwards, take a few minutes to divert to Cortachy, just past Dykehead. Although just off the well-trodden path, Cortachy has some real gems, including a fine castle. Unfortunately the castle is not open to the public, but can be seen from the road leading to Memus.
