Please note that the tunnel may be closed seasonally and not accessible during these periods. This is currently the case, as of the beginning of July 2025, as the tunnel is (again) being used for irrigation purposes.

The special thing about the Blue Grotto is the story of its creation: 2000 years ago, in Roman times, people were working diligently here and searching for silver-containing galena. The geologist Peter Gstrein suspects that the fire-setting method was already being used for mining in the first centuries after the birth of Christ; The rock's rock became brittle due to the heating and could therefore be chipped away more easily. This is how the Blue Grotto was created, which is probably unique in Tyrol. The blue grotto is located at the end of the Rosengartenschlucht just before the hiking trail arrives in Hoch-Imst. In the opposite direction from Hoch-Imst, the Blue Grotto can be reached in less than 10 minutes. Imst.at

1km location tunnel path through the darkness torch flashlight sturdy shoes

Overcome your fear and go into the almost 1000m long tunnel. Nothing for people taller than 1.95 m ;-)

Absolute highlight in summer

Don't forget a flashlight and definitely good shoes. It can be wet in the tunnel. The almost one kilometer long tunnel is easy to walk on. A real adventure.

Super exciting and cool, just watch out for your head and watch out for waterproof shoes! 😅

A little above the gorge - almost a bit hidden. Duck your head!
