Isla del Sec is a boat-access wreck dive in Palma Bay, Mallorca, centered on three scuttled fishing boats that now sit in a rocky seascape. It is a good fit for relaxed boat days and second dives, with the shallow wreck still offering clear structure and the deeper boats adding more classic wreck interest. Expect barracuda, moray eels, octopus, scorpionfish, nudibranchs, and other reef fish around the hulls and surrounding rock.
