Dont be tempted to park on Tesco they are proper on top about it on match day, id go for the Cockhedge car park personally its only a 5 minute walk away
We've used the big car park near to the ground and its a nightmare getting off it. There is a side road off Bewsey road called Pitt street where we and a few others park. It's about a 5 minute walk from the ground and free of yellow lines and residential restrictions etc
