Michelin’s ViaMichelin.com for general maps of Europe, quite accurate for France (less so for Switzerland, Italy, and other countries). Also has “good” satellite views (not in Switzerland, but see map.search.ch).
French IGN maps of France and territories (now works very well).
Austrian maps Austrian Map online (only supports certain versions of the Java plug-in, but lately works on the Mac (very tiny window that becomes smaller if you click to make it bigger, but increase the size of your browser window so it is much larger than your screen and you should be able to see something) as well as on many Windows PCs with the right plug-in installed). One can access these maps through Bergfex.at and use “vollbild” and turn off various information in order to get a better view and move around a bit quicker.
Austrian Kompass maps at gps-tracks.com (select Karten and Topo Österreich). These maps are far easier to navigate than Austrianmap ones and looks like Kompass has mostly copied their material from the official maps. But Austrianmaps gives better results when searching and shows more accurate topographical height lines.
Switzerland maps at Bundesgeoportal works best.
Switzerland maps at map.search.ch has other information and good satellite views, which ViaMichelin lacks here.
Liechtenstein maps are available at the government portal.
Slovenian maps at NVAtlas.
IGN maps of Spain covers all of Spain.
Another Spanish IGN maps portal CNIG which really only works, and then poorly, in Windows.

Other maps of Catalonia at Hipermapa (does not seem to work well).

Maps of Lombardia region.
Trentino region detailed maps.
Bolzano region detailed maps.

Friuli-Venezia-Giulia region detailed maps.
Liguria provincial maps.
Bavarian maps (south Germany).
gpsies.com are good to use for measuring distances and for being able to switch between Google and Microsoft satellite maps (as the other one is usually good where the other is not). As to route creators – they all have limitations and problems, but besides this site you can also try bikemap.net and tracks4bikers.com
