Ride along an alpine motorway for the first 20 min. Then follow a pine forest road for another 40 min, passing by the lake Leopoldsteiner See (altitude: ~630m) and making a brief stop there. After another 20 min along the motorway, finish in Eisenerz - a picturesque historic iron ore mining town. During the final approach you will have the open-pit iron mining mountain Erzberg in front of you almost all the time.
There is also a walking video around the lake Leopoldsteiner See (which you can also "ride" on your home bike).
