Three Hours Around the Sella del Diavolo: A Coastal Cruise from Cagliari

Cagliari sits on the southern coast of Sardegna, opening onto the Golfo degli Angeli. On this three-hour group cruise you leave from the Marina di Bonaria aboard the Mimì 9.50 and sweep around the Sella del Diavolo, a jagged limestone ridge that frames the eastern edge of the city’s shoreline. The tour is small by design—maximum ten guests—so the pace stays unhurried: short navigations between coves, brief anchorings for swims, and time to linger on the boat’s broad sun decks.

The itinerary threads a string of coastal features that read like a sketchbook of southern Sardinia: Cala Bernat’s steep cliffs, the cavernous grottos carved into the coastal rock, the sheltered bowls of Cala Fighera and the pebbled inlets at Calamosca. From the water the long sweep of Poetto beach reads differently—farther, wider, and edged with a shimmering band of Posidonia beds. The captain chooses stops according to wind and swell, which means each trip can feel like a bespoke coastal reconnaissance rather than a rote sightseeing lap.

Water here is famously clear. Stops invite snorkeling over rocky bottoms where small Mediterranean fish, occasional octopus, and beds of seagrass (Posidonia oceanica) make the shallows lively. The Mimì 9.50 is a classically styled boat with stable handling and generous sunbathing areas; soft drinks and local snacks accompany the leisure, leaning into an afternoon that balances exploration and ease.

Practicalities matter: departures begin at Marina di Bonaria; exact meeting details are supplied at booking. The route, stops, and safety decisions are made by the captain and are subject to weather. The tour’s small size is its standout feature—intimate viewing, easier access to narrow grottos, and a relaxed rhythm that larger charter boats cannot match.

This sail is an excellent first-sea outing for visitors based in Cagliari who want to experience the coastline beyond the city streets, and for swimmers seeking quick-access snorkeling without a full-day commitment. Operator contact details are not provided in the listing; book through the linked reservation to receive meeting instructions.

Onboard safety briefings cover lifejackets and basic snorkeling guidance, making the cruise accessible to confident swimmers and families with older children. Because the boat does not dock at beaches, expect short jumps into the sea from a low platform rather than a sandy landing. Bring reef-friendly sunscreen and a towel; if you want to photograph the cliffs up close, request a bow seat when you board. Reservations are recommended during summer weeks when local and international visitors fill Cagliari’s marinas.
