Hi Mapbear, the trails come from Rother Wanderführer Schottland, Rolf Gantzhorn, 2019 ed., if you own the book you can download, but usually the trails in the Rother Books are not very accurate. At least what I have seen in Cyprus and Greece... many hikers from German language countries use these red book, in fact in some remore region nearly all hikers. A should have referred to the as RW20 as i did with the other day sections, but somehow I forgot, RW20 stands for Rother Wanderführer Trail No. 20. I know, the Rother is sometimes a problem, as they recommend hikes which are not waymaked properly, but in scotland this seems to be the case quite often, in Greece, thats the usual case, can't see much in the field. Regards from Switzerland Martin
