All these maps are full colour on one side, with information in black and white on the reverse. The paper varies and seems to be lighter on later editions. The unfolded size also varies but is always larger than A1. All maps are at a scale of 1:50 000, with full contour detail at 20m intervals, and Lat/Long lines for GPS users. None of the maps have ISBN numbers. Firmly based upon Peter Slingsby’s maps of the 1980’s [a lot of info and most of Peter’s symbolisation copied directly without any acknowledgement at all!], these maps are the best Berg hiking maps currently in print.
