Mt. Pilatus, Lucerne, Switzerland.  There are many ways to reach the top of this mountain and they include hiking on foot, riding the aerial cableways and gondolas or taking the world's steepest  cog-wheel railway.  But no matter how you reach its highest peaks (2128 m or 6982 ft.), the views of the Alps will leave you speechless.
