Lungomare Beach is a shore dive on Cala Gonone’s urban waterfront, where a shallow rocky reef sits close to the promenade and town services. The route is simple and low-friction, with enough limestone structure to make a slow out-and-back or training lap worthwhile. It suits easy scuba, and the shallow fringe can also work for relaxed snorkeling on calm days. Choose a calm sea state and expect the entry line to feel busier than the reef itself.
