The man was climbing in Tirol, Austria with a group of five Germans when he fell near Nördlinger Hütte, close to Innsbruck.
The Tiroler Tageszeitung reported that the group was making their way down the mountain at around 1.25pm when the 77-year-old slipped and fell over the edge.
Police said he fell down a steep slope and then into a rocky gorge. A rescue helicopter came to his aid but he was pronounced dead at the scene.
