3. Mount Rainier, Washington
Elevation: 4,392m (14,411ft)
There are many routes on Mount Rainier, ice climbing, mountaineering, skiing, even rescue schools are organized here. That is one of the things which makes this mountain one of the best mountains to climb, not to mention the extraordinary landscape and nature that you would go through, but that is the feature of all these more “extreme” and isolated places, isn’t it?
