The most consistently observed species are the Two-banded Seabream, White Seabream, Tompot Blenny, and Turkish Wrasse, all of which appear across the majority of sites.

Less frequent but recorded sightings include the Lesser Spotted Dogfish, Great Barracuda, and the Cratena Slug.
The majority of sites are rated beginner level, including shore-entry options such as Espigon Wela A and Pecio La Dragonera, as well as shallow boat dives like Vapor del Miracle. A smaller number of sites, such as Els Arbrets and El Biotop, are rated intermediate and are better suited to divers with more experience. Currents across the region are generally mild.
Some wreck sites, including Pecio La Dragonera, are accessible directly from shore, while others such as Vapor del Miracle and El Vapor require a boat. The choice of entry depends on the specific site, so it is worth checking with one of the local operators such as iDive Barcelona or Medusadive when planning your trip.
Barcelona offers a varied mix including artificial reefs, natural reefs, wrecks, seagrass beds, walls, and at least one cave site. Artificial reefs like El Biotop and Port Olimpic attract dense fish life in relatively shallow water, while wreck sites such as Heinkel He 111 provide more technically engaging dives at greater depth. Seagrass sites like Cimodocea are calmer and particularly good for observing smaller species.
