Topographic map of the Zillertal

This very nice and topographic map of the Zillertal is even more detailled than the Garmin Topo Austria map. It includes trails, peaks and POIs. As the map is transparent you can use it together with other maps. The site is only in german, but it's still possible to find everything, and in case you get lost google translate might help you. The map can be downloaded as a single .exe file which extracts itself and integrates the map in Mapsource. From there you can then send it easily to your Garmin GPS device
