It is almost perfectly circular in shape and its steep cliffs plunge 1,500 m below sea level while the unsubmerged part rises 675 m to its summit. Alicudi is the wildest of the islands, where cars are not allowed, and is inhabited only on the east side, which slopes more gently towards the sea.
L’Isola Immediately after the Second World War, the island was populated by over 600 people, the majority of whom later emigrated to Australia. In 2001, the population was below 100 but residents are even fewer in the winter months.
