The directions for this walk are inconsistent - stages 1 to 4 are written such that even the most inexperienced hill walker can follow them, then at stage 5 suddenly you're on your own and advised to make a "beeline" for a small cairn that is obviously far too far away to be observed from your current position. This annoyed me to the extent that I just turned round and went back the way I had come.

That said the views of Loch Lomond and surrounding countryside made the walk worthwhile.
