ASO - Ustica
The ASO wreck, a motor vessel that went down in 1979, lies upright at 30 meters. It’s a respectable size at nearly 60 meters long, and we’ve found it’s a good spot for a single dive, offering plenty to explore without feeling rushed. The hull is largely intact, though time and the sea have certainly taken their toll, opening up some interesting swim-throughs into the cargo holds. Around the bridge, you’ll usually find clouds of damselfish and small groups of barracuda hanging in the blue. It's a solid dive for anyone comfortable at depth and looking for a classic Mediterranean wreck.
