We like the Kompass hiking maps of Europe. The maps are all topographic maps with trails, huts, and other hiking information added. Most of the maps include a separate German-language text booklet describing the area and the hiking trails. In many cases the maps are more useful to a hiker than the government topographic maps. Most maps are either in Italian or in German, often with an English legend. Please do not let the non-English nature of these maps stop you from buying them - they are great. ISBN prefix is 3-87051 in all cases.
We have on-line all of the indexes for the Kompass maps. Please note that many sheets have a leading "0" which must be included in the number - "73" and "073" are different map sheets. Those sheets without a leading "0" are 1:50,000 sheets; those sheets with a leading "0" are at other scales, typically 1:35,000 or 1:30,000 or 1:25,000.
