El Castillo is a beginner-friendly dive site near Mazarrón on the Murcian coast, reaching 15 meters depth near the remains of a coastal castle. The site features a rocky reef extending from the historic fortification into the Mediterranean, with scattered boulders, sand patches, and small overhangs creating varied habitats. Octopuses, moray eels, and nudibranchs inhabit the crevices, while schools of bream and mullet provide constant movement. The castle ruins above water add historical atmosphere to the dive, and the sheltered bay provides reliable calm conditions. Easy access and gentle depths make El Castillo a popular choice for training and recreational diving in Mazarrón.
