The first time we saw Etna we were several hours away. Driving through a valley, we stopped and said, “it has to be”, and of course it was. The many faces of Etna, the magnificent views, the snow caps and the sheer power of this volcano makes us respect mother nature. You can take a travel up the mountain but I was told there is only one tour operator – not sure about that. But you should reserve well in advance and this time there was just too much snow.
