Stromboli was formed a mere 40,000 years ago and its gases continue to send up an almost constant spray of liquid magma. The most recent volcanic eruptions took place in February 2007 when two new craters opened on the volcano’s summit, producing two scalding lava flows. Although seismic activity, including rock falls, continued for several days, no mass evacuation was deemed necessary.
Though the "normal" small eruptions of lava are not dangerous, you should be aware of the possible danger. The local authorities are very aware of Stromboli's state, you should listen to them. If paths to the craters are closed, don't go there. Never climb up the volcano without a local guide. Don't leave paths.
Tours up the Stromboli aren't easy walks. You should be well-equipped, healthy and in good physical condition when going there. As Stromboli is small and its environment is sensitive, you should treat it carefully.
Many thousands of tourists visit the volcano each year. It takes four hours to reach the island from Lipari by ferry, or 1½ to two hours by hydrofoil. Visitors are strongly advised to book their ferry tickets to Stromboli online in advance. Hydrofoils run from Stromboli to the other Aeolian Islands, each of which has its own attractions. You may have to change boats in Lipari, largest and most populous of the Aeolian Islands, and the main transportation hub for the archipelago.
There are two villages on the island, the larger Stromboli and the much smaller Ginostra, a former fishing village rarely visited by tourists (although tourist services are about all that remains there). It is not yet feasible to walk between the villages (although a trans-island hiking trail is under construction as of 2007), and the only way to travel between them is by boat. Together, both villages only have about 350 inhabitants. The villages, which are almost unchanged by tourism, are worth a closer look, especially the rather hidden Ginostra with the smallest European port (one boat only!) at all is nice to see. There is a nice beach with fine black lava sand in Stromboli, where one can relax and swim in the sea.
Due to the size of the island and lacking streets, neither cars nor buses or trains exist. The only available means of transport are "ape-cars", small motorbikes and boats. The only other way to move around the island is by walking. Note that there are no streetlights in either village, and if you're out after dark, you'll be well advised to use a flashlight. Although, while passing this island on a cruise, a passing truck was seen driving on the perimiter to what looked like a lighthouse.
