The Czech map service Mapy.cz is also really good for hiking. For example, this is the same location compared with Google Maps (if you have a high density screen, I recommend setting zoom to 75% on mapy.cz):
It's the very best hiking service in Germany also. Google maps is only usable for cars or bus/train. But for hiking or bycycling Mapy.cz with OSM are the best.
