Unpredictable weather, falling rocks, slippery walls and extremely steep climbs only make the trip more dangerous.

Classifying the most difficult and dangerous mountain climbs is not easy. Numbers can be taken out of context, anecdotes can be exaggerated and assumptions can be wrong. Also, climbing can be less difficult than descending because people are exhausted and cold, but still have to make it down alive.
