I recently had time to think about next summer and thought I'd might have a look at Poland and the Baltics around June or July. The idea is to head to Slovakia first, then cross into Poland near the Ukrainian border in order to travel north and eventually arrive at the Lithuanian border near Sejny. Now I'm looking for advice concerning Poland: Are trails / logging roads publicly accessible? What about camping? Any advice on where to find gps tracks for trails or gravel roads?
