Overview: CATANIA, SICILY: Europe's most aggressive volcano, Mount Etna, is located on the Italian island of Sicily. You'd think that given her frequent hissy fits, the latest one which was yesterday, this volcano would be off limits to the general public. But that isn't the case. Mount Etna is Catania's biggest tourist attraction and a mighty entertaining one I must add. I didn't know quite what to expect as I jumped into the funicular taking me half way up the mountain but I knew I was in for an adventure. And Mount Etna didn't disappoint.
