Bath Road (A368)
Skirting the northern edge of the Mendip Hills, the A368 is a primary route that still manages to deliver a scenic punch. The road is wide and mostly smooth, punctuated by long, open curves that follow the natural topography of the foothills. It is a straightforward, pleasant drive with excellent sightlines across the reservoir and the valley floor.
Commuter traffic builds up quickly near the Bristol end; run it mid-morning for a clear run at the faster bends.
