After our morning walk through Salzburg, we went up to Hallein (about 30 minutes outside of Salzburg in the hills) and toured the salt mines. We were given coveralls and walked, rode a small train and at times slid down metal chutes through over a mile of tunnels. Deep into the mountain, we actually crossed the border into Germany and then looped back around into Austria. We learned all about the history of salt mining and the wealth it brought to the area.
