The Duke's Pass
A821Aberfoyle to Callander
A twisting climb through the Trossachs between Aberfoyle and Callander.
The A821 Duke’s Pass winds up through forest and rock in the heart of the Trossachs, with lochs glinting below. It is narrow and busy with visitors in summer, so take it gently and use the forest car parks to stop.
If we could bottle one Scottish drive for someone short on time, it would be this. It feels like the Highlands folded down to fit inside an afternoon.

“The Dukes Pass may be brief, however it offers a density of turns that shames much longer roads, with no two corners alike, all set in a landscape that has inspired novelists and poets for generations.”
