The GEOTour starts at the GEOMuseum Radein/Redagno which shows the Bletterbach canyon’s special geological features. Our tour leads through a forest to the so called “Zirmersteig” (trail). Then we go down the canyon and follow the river upwards to the head of the valley (“Gorz”). From here we have to walk back to the “Gorzsteig”. This trail leads to the Visitor Centre GEOPARC Bletterbach in Aldino. From here we have two possibilities to return to Redagno/Radein: to walk back or to take the bus.
