Should have said we came back on the A28 no problem apart from having to go into the outskirts of Rouen thought we'd gone wrong at first but just follow the autre direction signs and you end up back on track.From the lLoire ,Saumur it cost us 24 Euros that was for a car.
Amazing family weekend with old steam engines, classic car displays, market stalls, and full catering and bar. And camping on site - Save £25 by booking in advance.
