Cretaccio Island Wall

Cretaccio is the smallest and least visited island of the Tremiti group, an uninhabited chalk outcrop whose underwater perimeter is a continuous vertical wall from the surface to 40 metres and beyond. The wall is blanketed in orange and violet sponges, red corals, and enormous gorgonian colonies, and the deep sections regularly produce surprise encounters with large amberjack and sunfish. The solitude here is profound — almost no dive traffic compared to San Domino — and the wall life is correspondingly undisturbed.
