Vernazza's underwater character is defined by a dense cluster of wrecks sitting at a range of depths, from accessible intermediate dives to demanding technical sites requiring trimix. Boat access is the norm across all sites. Reef diving at spots like Lamacrèxia offers a gentler introduction, while the European Common Cuttlefish and an assortment of wrasse species appear consistently across the area. Snorkelling sites add a shallower dimension to the mix.
