Hi Sid as you are entering Vernon turn left just before the river, it is signposted for Giverny. As you are entering the village there is a roundabout with parking either side, ignore these as they have very low height barriers, carry along for about 100mtrs and turn sharp left (signpost parking). this looks quite a narrow but is one way and OK. on the left there is free parking on three terraces, go to the top terrace this is where we stayed , its best to get there either after 1800hrs and stop the night or get there early in the morning if stopping elsewhere as it gets rather busy. The carpark is next to some cafes and the entrance to Monet's house and gardens.If you need any more info just ask
