In The Trossachs, close toLoch Katrine is the 'Bealach Nam Bo' - the Pass of the Cattle, where the highland cattle rustlers found the only place where they could take their cattle past the narrow pass of the trossachs. Todat there are no rustlers at the \Bealach nam Bo although there are sometimes a few highland Cattle.
The walk to the pass is beautiful, starting at the narrow Trossach pass and ending high above Loch Katrine.
