Marina Portus Karalis (Portus Karalis)

Marina Portus Karalis sits right in the heart of Cagliari's working harbour, putting you steps away from the city's historic centre, shops, and top sights. It's one of the few marinas in Sardinia with berths for superyachts up to 90 metres, spread across two large docks with 118 total berths. The blend of urban buzz and deep-water capability makes it stand out — you're docking in a real city, not an isolated marina complex.
