Going to this (remote) area in The Netherlands, one should start driving in the direction of Nijmegen and there follow the signs to "Berg en Dal" / "Groesbeek". In the village itself, the Liberation Museum and Canadian Cemetry are well appointed directions.
From Nijmegen (e.g. central railway station) you can take a bus no. 5 to Groesbeek. The distance is about 10 kilometers, that's a 25 minute drive by bus.
