World's most beautiful mountains

The most beautiful mountains in the world have captivated climbers for centuries. “You are not in the mountains. The mountains are in you,” said John Muir, the renowned naturalist, author and environmental philosopher. Muir makes a valid point. Those who spend time in the mountains seem to be driven by a deeper force. These brave men and women will face vertiginous vertical falls, sub-zero temperatures and 8,000m death zones in pursuit of their summit dreams. It’s in ode to them that we present this calendar of the world's most stunning peaks.
