Abela Healing Tunnel (Former Slate Mine Grube Felicitas)

The former slate tunnel in Bad Fredeburg, right in the heart of Mother Earth, warmly welcomes holidaymakers, spa guests and wellness enthusiasts. In the Abela Heilstollen - Abela means "breath" in Hebrew - you can breathe in the soothing air in peace and quiet on special relaxation loungers and in warm sleeping bags.With an inside temperature of a constant 9 ° Celsius, the air in the tunnel is almost saturated with water vapor (almost 100% humidity). The air you breathe in the Abela Heilstollen is pure and absolutely pollen-free. Due to the "laminar" (non-turbulent) air flow, the air constantly cleans itself.Source: abela-heilstollen.info/abela-heilstollen.html
