El Arco de San Andrés

El Arco de San Andrés is a scenic dive site near Carboneras in Almería province, featuring a magnificent natural rock arch that frames a stunning underwater vista. This beginner-friendly site offers divers the chance to swim through the arch, which is adorned with sponges, bryozoans, and small gorgonian fans. The surrounding reef is home to groupers, moray eels, and schools of saddled bream, while nudibranchs and sea slugs add splashes of color to the rocky surfaces. The arch creates dramatic light effects as sunbeams penetrate the opening, making this a favorite spot for underwater photographers exploring the Almería coastline.
