Generally yes.
However the frequencies are not neccessarly self evident for the average VFR rated GA pilot. E.g. for Friedrichshafen TMZ you are not supposed to monitor Friedrichshafen Tower but some swiss Zurich Radar frequency. If you use the official DFS charts, the information is there. However in some EFB Software it is not. Skydemon has it though.
Of course it's written down in the AIP. Burried somewhere in ENR - Other Airspace (or similar) IIRC
