Cockerham, Lancaster and A6 to Carnforth. Then Kendal, Shap, Lowther, Penrith, Carlisle, then //M74 via Gretna (services) to beyond Abington (services), Kirkmuirhill west on B7806 via Strathaven and A726/A727 to Darnley, Paisley, Helensburgh, Inveraray, Dunbeg (NE of Oban), Fort William, Inverness, Fort William, Tyndrum/Crianlarich, Dumbarton, Paisley
1. Return route from Paisley is the reverse of the way north.
2. Carnforth to Kendal via Burton (A6070/A65: less climb and far less busy than A6 and A590 dual carriageway).
3. Have routed on A82 from Ft Augustus northbound (keen to get to Inverness stop) and then SE of the loch via Foyers for the return.
4. This route plot takes the excellent (surface and wide) canal towpath for the bit south of Ft Augustus and then again drops down to the canal past the Commando Memorial (photo) above Spean Bridge to take the towpath to Banavie and Ft William. Recommended (and flatter than boring A82).
