|Route outline (key)|
The A809 runs north-north-west for 12 miles from Bearsden, in the outer suburbs of Glasgow, to the village of Drymen, a popular tourist destination lying between Loch Lomond and the Campsie Fells.
The route begins at Canniesburn Toll roundabout, a junction with the A81 and A739, half a mile south-east of Bearsden town centre. Heading along Drymen Road, we pass Bearsden railway station, before meeting the short A808 at the light-controlled Bearsden Cross and then, a little further on, the A810 at a triangular junction known as the Stockiemuir Diamond; the A810 is the forward direction here and our road TOTSOs to the right, to become Stockiemuir Road.
At Baljaffray roundabout we cross the B8050 and then skirt the Castlemaine Estate on the western fringe of Milngavie. The route so far has brought us through some of outer Glasgow's most affluent residential areas, but now we leave the suburbs at last and start a steady climb through the countryside of East Dunbartonshire. Our ascent is briefly interrupted where the road dips down to cross the Craigton Burn and Allander Water, and after the latter we pass the (now closed) Carbeth Inn, once a popular bikers' haunt.
The B821 leads off to the right at Carbeth, heading towards Strathblane and the A81 which has shadowed our own route the whole way. Shortly afterwards we pass the Auchengillan Outdoor Centre and then the Queen's View viewpoint at the road's summit. Continuing north, we start to descend, passing Stockiemuir, Craighat, and then a junction with the B834, which turns right to cross the A81 and head for Killearn.
Approaching Croftamie, we cross the Catter Burn and encounter our first speed limit since leaving Milngavie, the road bending to the right to pass through the village. Half a mile further on and the A809 reaches its terminus, running into the A811 just south of Drymen Bridge.
