We are travelling from Salisbury on Saturday 27th july and are heading for Padstow. I was thinking of stopping off near Exeter to break up the journey, but i really dont want to get stuck in traffic. does anyone know the best time of day to avoid or the best routes to avoid traffic. I was thinking of leaving salisbury around 530 am. or would it be better to leave mid-late afternoon? Any tips gratefully received. Thanks.
