Yes the island of Vulcano is always erupting! If you go to Sicily - you must go to the islands Vulcano, Lipari, & Panaera. These little islands will take your breath away! I stayed in Lipari and is the best place to stay within these little islands. Everyday you can take a speed boat from island to island. From the mainland, take the ferry or speed boat over from the main train hubs Milazzo or Messina located at the northeastern point of Sicily. It's not the easiest to get to but I promise you will talk about it for years to come!
