The Sciara del Fuoco — Stream of Fire — is the steep, blackened slope on the northwest face of the island where molten material slides from the summit craters straight into the sea. By day it is a desolate avalanche track of pumice and ash; by night, when the eruptions become visible, it glows red.
Local boat operators run two-hour sunset trips from Stromboli village and Ginostra around to the Sciara side. You drop anchor a few hundred metres offshore as the light fades and watch the bursts from the water. The trips run reliably from June through September; expect to pay around 25 to 35 euro per person.
