The route is rural and goes through some pleasing countryside to Tiverton.
Tiverton Castle is just north of the town. It looks a bit like a manor house with battlements drawn on, but looks a popular visit. National Trust property Knighthayes House is also an option.
However a drive to Dunster Castle through the Exmoor National Park looks a great option and from there a night in the seaside resort of Minehead looks like a tantalising opportunity to try a night at Butlins.
Overnight: Angel Guesthouse, Tiverton. The guest house was a star in television’s 4 in a Bed.
