Unfortunately this was a disappointing visit for us. We had booked two nights in Milazzo on the Sicilian mainland to use as a base for visiting the Islands, but on our first day the weather was perfect and the seas horrendous - no boats were running! The second day, the weather was horrendous but the seas perfect - boats were running but in heavy rain. In the end we managed the ferry out to Vulcano, visited the sulphur vents just near the docks, and managed to climb up the crater as well. The hike was about as enjoyable as any hill-climb hike in heavy rain can be, which is to say not especially! We eventually admitted defeat in the early afternoon and returned to Milazzo, hoping to return another time in better weather. It does seem like a nice spot, but not one I can really leave an honest star-rating for.
