Punta Pennello is the west-tip Giannutri wall for divers who want a technical, structure-rich boat dive. A broad shelf drops into a broken wall with caves, crevices, and ledges wrapped in gorgonians, sponges, and Posidonia. The site rewards good buoyancy and current awareness more than depth chasing, with roomy lines out over the wall and a more committed return once the flow picks up. Expect barracuda schools and a mix of reef fish and crustaceans in a protected marine-park setting.
