Starting, as the box says, at Fair Cross on the B3190, a little to the south west of Washford, the B3188 finishes almost due south in Wiveliscombe on the B3227, although it is far from straight!
We set off in a roughly south-easterly direction towards Monksilver, then pass the Combe Sydenham estate (links to Drake - his wife came from here; now a country park), to reach the B3224 at Elworthy Cross. While the road passes plenty of farms and houses as it continues south, it misses the villages of Brompton Ralph and Tolland, only seeing any real village scene at Pitsford Hill before reaching Ford. Here the road, which has already turned back to a roughly south-westerly direction, suddenly reaches a pair of right-angle bends to weave between the houses and farm buildings. A gentle curve then turns us west, before a sharper one returns us to the south and into Wiveliscombe.
Wiveliscombe is a pretty market town to the west of Taunton, and once sat on the busy A361 route. However, that road has long since been re-routed, so we now reach the B3227 a little to the east of the town centre, at a staggered crossroads with Station Road, although the railway is long gone.
