Legendary mountains continue to lure adventurers. In some cases, the more difficult the climb is the better. But astonishing mountains can also be easy to conquer. The routes to the top of a summit range from length and difficulty, to geology and surrounding scenery. Some people prefer rugged unpaved terrain, while others opt for a marked route to avoid surprises. Mountaineering does not have to be hard. But some preparation and careful mountain selection can bring even some of the world's highest peaks within reach of a fairly average Joe.
