Cagliari Boat Tour: Swim, Snorkel & Sip Prosecco by Sella del Diavolo

Summary

Swim in hidden Cagliari bays snorkel caves sip prosecco with locals

You’ll start right in Cagliari’s lively port with a local skipper guiding your small group along secret coves and limestone cliffs like Sella del Diavolo. Swim or snorkel in clear blue water, spot dolphins if you’re lucky, and share snacks plus a glass of Prosecco on deck before ending at Poetto Beach or returning to town—all gear included.

What’s the experience like?

We stepped onto the boat right in the middle of Cagliari’s port—honestly, I was still finishing my coffee when our skipper, Marco, waved us over. He had this easy way of talking about the city’s history as we pulled away from the docks. The skyline looked different from the water—older somehow—and he pointed out where the old city walls used to stand. Dolphins showed up before I’d even put on sunscreen. Not kidding. They popped up in little groups, almost close enough to hear them breathe if you leaned over (don’t do that, by the way—Marco laughed at me for nearly dropping my sunglasses).

The first swim stop was this tiny cove you really can’t get to unless you’re on a small boat. Water so clear you could see every pebble on the bottom. I tried snorkeling for the first time—mask a bit foggy but fish everywhere, darting around like they were late for something. There was this moment when everyone went quiet except for splashing and a seagull yelling at us from a rock. It felt good just floating there, sun warm on my back and nothing else to think about except maybe how salty my hair was getting.

Later we cruised past these limestone cliffs—the Sella del Diavolo. Marco told us the legend (something about devils fighting angels for Sardinia; I probably missed half of it because I was distracted by how blue everything looked). At one point he handed out cold Prosecco and some snacks—simple stuff but honestly tasted better after swimming all morning. There was an option to swim into a sea cave if conditions were right; some folks went for it, but I hung back and watched light flicker on the water instead.

We ended near Poetto Beach—big stretch of sand with locals walking dogs or just hanging out at beach bars. You could stay there if you wanted (just let Marco know), but most of us drifted back to port together, salty and sun-tired. I still think about that first jump off the boat—the water shock-cold then perfect once you got used to it.
