You watch from the water in the dark with nothing between you and it. Stromboli has been in continuous eruption for at least 2,000 years, the 'Lighthouse of the Mediterranean' that guided ancient sailors. Its mild, rhythmic explosions gave geology the term 'Strombolian eruption'. Major paroxysms in 2019 and 2024 show it can turn serious; respect exclusion zones. Anchorage: Ginostra and Scari offer marginal anchoring; the volcano-watching is done drifting offshore. No shelter, this is a settled-weather-only stop. Hazards: No site-specific hazards noted, brief normally. Plus
