Just a quick note, in case someone is planning on coming to Finland, North Europe for hiking:
The Finnish forest ministry has free'd all excursion maps and topos from cover charges. You can build your own maps, and print them out here:
http://www.retkikartta.fi/retkikartta.php?lang=en
The maps include all official trails, wilderness huts, fireplaces, and a body of other information as well. You can choose which items/layers you wish to include in your map.
However, if you are planning a longer hike, either I suggest you print at a high quality copy store, or otherwise make sure your printed copies don't get wet!
