Favignana is the largest of the Egadi Islands, a low, bright island off western Sicily where limestone coves, old tuna-fishing wealth, and clear water do most of the talking. From Marsala or Trapani it looks close enough to touch on a clear day, and the hydrofoil ride is short enough to make the island tempting even as a day trip.
The classic Favignana day is simple: rent a bike or scooter, swim at Cala Rossa, look into the blue quarry water at Bue Marino, and leave time for the Former Florio Tuna Fishery. That old factory changes the island from a pretty swimming stop into a place with a deep, hard-working history.
Favignana is not untouched. In August it can feel busy, expensive, and too small for the number of people who want the same coves. Go in June, September, or on a weekday if you can, and the island becomes much easier to love.
