Heilstollen and Gradierwerke

Drop by drop, the water fights its way through the stone, tapping a gentle rhythm on the rocky ground. Otherwise you hear...nothing. Pleasant silence in the belly of the earth, total relaxation in the tunnel. Breathe in the purest air, fill your lungs with the purity from the depths of the mountains. Or treat yourself to a day by the sea, but without the annoying sand in your shoes. Brine water trickles over blackthorn, the scent of salty wanderlust wafts into your nose. Take a deep breath and enjoy.
