Which mountain is the most difficult to climb?

Answer 1

Which mountain is most difficult to climb?

The query is illogical; geographical scales and geological structure give proof of slopes and gradients on all ridges across Planet Earth, but it is a matter of opinion as to which mountain is the most difficult to climb. One face of the Matterhorn is nearly vertical, and almost entirely impossible to scale effectively; the high altitude at the top of Everest is dangerous to say the least and K2 is generally considered as extremely hard to overcome, more so than most others, but there is no direct answer to the question, unfortunately.

However, one could say Mauna Kea is the most difficult, because the largest proportion of it is submerged by water.
