Snorkeling in Cagliari: Sella del Diavolo with GoPro

The Pigeon's Cave sits carved into the cliff face, and you photograph it from the water.

Snorkel the Cagliari coastline aboard a small boat departing from the city port, with skipper, snorkeling gear and underwater camera included. You stop at five sites: the limestone cliffs of Sella del Diavolo, the sea cave carved into them, the turquoise shallows off Poetto Beach, the sheltered bay at Calamosca where beer and soft drinks are served, and the quiet cove at Cala Bernat. The boat holds a small group, and the skipper speaks English or Italian.

The experience

The boat leaves directly from Cagliari Port, a few minutes from the city center, so there's no transfer inland. Once aboard, the skipper briefs you on safety and you cast off toward the wild coast. Within minutes the city skyline recedes and you're navigating the limestone cliffs of Sella del Diavolo, the symbol of Cagliari. The boat slows at the Pigeon's Cave, a natural sea cave carved over millennia by waves and wind, and one of the most photographed spots on the coastline: the GoPro captures you against this backdrop before you enter the water.

You snorkel at five stops across three hours. The first is directly beneath the Devil's Saddle cliffs themselves, where the water runs deep and cobalt blue, ideal for testing your mask and filming underwater. Next is the transparent turquoise off Poetto Beach, Cagliari's main summer strand, where you float in the shallows and watch the long promenade from the water instead of fighting the crowded sand. At Calamosca, a sheltered emerald-green bay surrounded by nature, the skipper serves cold Ichnusa beer or soft drinks while you soak in the sun and the calm. The final snorkel is at Cala Bernat, a quiet local secret where the seabed is rich in marine life and the water clarity rewards your last underwater photos before the sail back.

Snorkeling gear and the GoPro are provided. You bring nothing but a towel and sunscreen. The small group size keeps the experience intimate, and if you're lucky, dolphins swim near the coast. The skipper is your guide throughout, narrating the sites and managing the boat's pace and stops.

Top questions

What languages is the tour guided in?

Live guide in English and Italian.

What happens if it rains?

It may be canceled due to bad weather. If that happens, you're offered another date or a refund. Free cancellation up to 24 h before the start.

Can I snorkel at every stop, or are some just for looking?

You snorkel at five stops: beneath Sella del Diavolo, off Poetto Beach, at Calamosca, at Cala Bernat, and near the Pigeon's Cave. At the cave itself you slow down to photograph and admire it from the boat, then enter the water at the next stop.

What's included in the price, and what do I need to bring?

Snorkeling equipment, the GoPro, beer and soft drinks, and the skipper are all included. Bring a towel, sunscreen, and a swimsuit. The boat departs from Cagliari Port so no separate transport is needed.

Is this suitable if I've never snorkeled before?

Yes. The skipper gives a safety briefing before departure, and the first stop beneath the cliffs is designed to let you test your mask and get comfortable in the water. The tour is suitable for all fitness levels.

What is the Pigeon's Cave, and why is it special?

The Pigeon's Cave is a natural sea cave carved into the limestone cliffs of Sella del Diavolo over thousands of years by waves and wind. It's one of the most photographed spots on the Cagliari coastline, and the boat passes close enough for you to see its size and wild beauty from the water.

How many people are on the boat, and will it feel crowded?

The boat holds a small group, which keeps the experience intimate and gives everyone space to snorkel and relax. The skipper manages the pace and stops for the whole group.

What happens if the weather is rough or dolphins don't appear?

The tour runs as scheduled. Calamosca bay is naturally sheltered and calm. Dolphins are a bonus if you're lucky, not a guarantee, but the five snorkeling stops and the Pigeon's Cave are the core of the experience regardless.
