Gasteiner Heilstollen

A radon healing gallery 2.5 km inside the Radhausberg mountain, where patients lie on beds in warm, humid tunnels for therapeutic sessions. The microclimate (37-41 degrees, high humidity, natural radon) is used to treat rheumatic and respiratory conditions. The Heilstollen is the single most distinctive thing about Bad Gastein beyond the waterfall.

The Gasteiner Heilstollen sends patients 2.5 kilometers inside the Radhausberg mountain on trolleys, where temperatures of 37 to 41 degrees and natural radon in the air treat rheumatic and respiratory conditions. Austrian health insurance covers it. This is not a wellness spa; it is a recognized medical facility inside a former gold and silver mine. Sessions must be booked in advance at the facility in Boeckstein, reachable by local train from Bad Gastein. A taster visit is available for non-patients. Combine with the Gastein Museum in Bad Gastein for context on the valley’s long history as a cure destination.
