For Aussies the battlefields of WW1 are quite some traveling away. Me, being Dutch, it’s easier. You just get in your car and drive for about two hours and your right smack in the middle of things. Of course Gallipoli is further away, but Verdun, Amiens and Ypres are more or less around the corner.
Ar Ypres (you actually pronounce it “ee pruh” and not “wipers”) you can just walk into WW1. It has a fantastic museum in the “Laken hall”, which was actually more or less rebuilt brick by brick.
But take a moment and google your way around the countryside: wherever you go, you will touch history.
