Cagliari Boat Tour: Snorkeling, Sella del Diavolo & Secret Coves

Swim wild coves and see Devil’s Saddle cliffs from the sea

You’ll slip into emerald coves near Cagliari with a local skipper guiding you past Sella del Diavolo’s dramatic cliffs, snorkeling in crystal-clear pools and pausing for laughter or quiet as you float beside wild limestone caves. Premium gear, soft towels, and small group comfort mean you can just be present—sun-warmed skin and salty hair included.

The Experience

The morning started with us running late — I’d somehow misread the meeting point and we almost wandered into someone’s garden instead of the marina. Our skipper, Andrea, just grinned and waved us over anyway. Sardinian patience is a real thing. The boat itself looked brand new (smelled like it too, sort of salty plastic and sunscreen), and there were only five of us plus Andrea. No big crowds, which honestly made me relax right away.

We set off from Cagliari’s harbor, passing old fishermen mending nets in that half-shade under the stone wall. The city faded behind us and suddenly it was just these white cliffs and turquoise water. Andrea pointed out Sella del Diavolo — Devil’s Saddle — and told some story about a fallen angel fighting for this bay. I probably missed half of it because I was busy trying to pronounce “Sella del Diavolo” without embarrassing myself (failed). First stop was Calamosca, where the water was so clear you could count every pebble on the bottom. I hesitated before jumping in; it looked cold but wasn’t at all — more like silk than sea.

Later we drifted into Cala Fighera, which felt wilder somehow, less tamed by people. There was this moment when everyone went quiet except for the slap of water against limestone — even Andrea stopped talking. We swam again at Piscine di Gasole behind the headland; I tried one of those anti-fog masks (they actually work) and watched little silver fish darting around my feet. Someone started humming softly, maybe just happy or maybe because that kind of silence makes you want to fill it with something gentle.

I’m not sure if it was the sun or the salt or just being away from everything for a few hours, but by the time we reached Poetto Beach I felt lighter than I have in months. The towels were fluffy (Andrea handed them out with a wink), and there was even a freshwater shower on board so we didn’t stay sticky all afternoon. It wasn’t perfect — I got sunblock in my eyes at one point and cursed in three languages — but honestly? That’s what I remember most: laughter echoing off the cliffs, salt drying on my skin, a sense that nobody needed to hurry anywhere for once.
