Whilst not nearly as dramatic as its neighbour in the Lauterbrunnen Valley, the Trümmelbach Falls, the Gletscherschlucht (or Glacier Gorge) is nevertheless an impressive place.
A narrow gangway has been built along the side of the gorge carved out by the melt waters of the Lower Grindelwald Glacier connecting a series of paths and tunnels leading ever deeper into the gorge until you come to — a gate.
Now according to the guide books we should have got to a point where the tail of the glacier was visible. But whether the path was unsafe beyond the gate, or whether the glacier had retreated too far up the valley, I wasn't able to establish.
There is an interesting collection of local geological specimens back at the entrance hall, and some information on the so-called Grindelwald Marble.
