The Gorner Gorge is the unique wonder of nature in the immediate vicinity of the Blatten hamlet. It was eroded by the Gornervispe River after the last Ice Age, and was first opened up in 1886-87. There are now two ways of crossing the gorge: the upper part of the Gornerschlucht can be crossed in a three- to four-hour breathtaking adventure with a guide, or the lower part of the Gornerschlucht can be crossed without special equipment. The rock here, serpentinite, is around 220 million years old. A natural spectacle, only 15 minutes from Zermatt.
