Olivetta is a Portofino marine-park shore dive built around a shallow entry that rolls into a gradual rock-and-wall profile over sand and posidonia. It suits mixed-level divers who want an easy Mediterranean reef with solid macro interest, including groupers, scorpionfish, moray eels, and yellow parazoanthus on the harder surfaces. The route is straightforward, but the site still rewards a calm day and tidy buoyancy.
