The road from Stirling starts with wonderful views of the castle on the rock before travelling North then west towards the Trossachs.
The land is dramatic with distant vistas of the mountains to the North. If you have the kids with you then a stop at Blair Drummond Safari park will certainly keep them happy. The road passes Doune whose castle will be familiar to you from Monty Python's Holy Grail movie. From then, it is 30 minutes on to the charming village of Callander.
