The current B837 is a popular tourist drive, connecting the pretty village of Drymen to the bonnie banks of Loch Lomond at Balmaha. This dead-end road was originally unclassified but had gained its present number by 1932.
We start on the B858, former A811, in the centre of Drymen and head north west, quickly leaving the village behind. The first bit of this road is a little bit like a roller coaster as it climbs and drops over the undulating ground along a series of short straights. The road becomes a bit narrower as we squeeze through the tiny village of Milton of Buchanan, where we pick up the West Highland Way. It's then downhill all the way to Balmaha, with its large car park and visitor centre. From the loch pier ferries ply their way across Loch Lomond, allowing visitors to explore some of the islands. An unclassified road continues north along the shore to the hotel at Rowardennan and the B837 ends when the road bears sharply right onto this.
