Catania: Gulf Scuba Diving Tour with Marine Biologist
Catania’s best underwater scenery comes from its volcanoes. This small-group scuba outing takes you across the Gulf of Catania and around the Cyclopean Isles, where ancient lava flows form basalt columns, lava ropes, underwater faults, and sandy patches alive with fish. The marine biologist guide adds meaning to what you see, rather than leaving you to stare at rocks and guess.
I like two things especially: the calm instruction from guides such as Andrea, and the chance to see the volcanic seabed at close range. The team gives first-timers time to settle in, checks on you underwater, and may point out octopus, starfish, crabs, bream, sponges, and gorgonians. The main drawback is that conditions can affect the plan, and the underwater portion may feel short if you want a long technical session.
Key points
- Volcanic seabed: Swim beside basalt columns, lava ropes, pillows, canyons, and faults in the Gulf of Catania.
- Strong beginner support: Andrea and the team explain the equipment step by step and stay close in the water.
- Marine life sightings: Look for octopus, bream, starfish, crabs, sponges, gorgonians, and schools of young fish.
- Cyclopean Isles setting: The boat ride adds views of Aci Trezza and the protected waters around the islands.
- Half-day commitment: The activity is listed at 3.5 hours, with the Cyclopean Isles portion described as lasting about four hours.
- Price and flexibility: At $82 per person, equipment and a professional guide are included, while hotel transport is not.
Lava, fish, and the Cyclopean Isles

The appeal here is not simply breathing underwater. It is seeing how Mount Etna and Sicily’s volcanic past continue below the sea.
From the boat, you head toward the Cyclopean Isles near Aci Trezza, a striking coastal area known for its dark volcanic rock. Below the surface, the lava becomes a maze of hard edges and rounded forms. You might pass basalt columns, pillow lava, rope-like flows, white sand, and openings shaped by old volcanic faults.
That mix gives the seabed more character than a flat reef. One moment you are looking into a narrow canyon. The next, your guide may draw your attention to a fish sheltering beside a sponge or an octopus tucked between rocks. The scenery changes in small, close-up ways, so you need to slow down and keep your eyes open.
The Cyclopean Isles are also part of a marine protected area. The setting matters because the trip is not only a lesson in scuba technique. It is a gentle introduction to how geology, fish, and marine plants fit together along Sicily’s coast.

Meeting the Etna & Sea Excursions team

The activity begins at Etna & Sea Excursions. Hotel pickup and drop-off are not included, so you need to make your own way to the starting point.
Andrea is the guide name that comes up repeatedly in the experience details, and he works with a wider team that includes instructors such as Jerry and Rosario. The team speaks English, French, Italian, Portuguese, Spanish, and German. An audio guide is also available in French, Spanish, Portuguese, and German.
The instruction is a major part of the value. You do not simply receive a tank and step off the boat. The team explains the equipment and basic underwater rules before entering the sea, then goes over the process again in the water. If you are anxious, that second explanation can make the difference between a tense outing and an enjoyable one.
Small groups are used to give the instructors more time to watch each person. That is particularly useful for a first attempt, when clearing your mask, breathing through the regulator, or adjusting to the weight of the equipment can feel unfamiliar.
What the boat trip adds

The boat ride carries you toward the Cyclopean Isles and provides the setting for the activity. It also gives you time to look at the Sicilian coast from the water and hear about the islands, the volcanic rock, and the area around Mount Etna.
The trip includes a sailing element, marine life viewing, and an aperitif. Some outings have also included time to relax on the boat or snorkel after the scuba session, but these extras should not be treated as guaranteed features unless they are confirmed for your departure.
The boat ride is not the main event, and that matters if you are booking this strictly for underwater time. One person found the ride longer than necessary. I can understand that view, especially if you already have scuba experience and want maximum time below the surface. For first-timers, though, the boat gives you a slower start and lets you become familiar with the guides before entering the water.
Getting comfortable with scuba gear

The equipment is included, which makes the $82 price easier to assess. You do not need to arrange a separate rental package for the basic gear supplied by the operator.
The first stage is practical. You learn how the equipment works, how to breathe, and what to do underwater. The instructors also cover basic signals and safety procedures. You should expect the team to take this slowly if you are new, rather than rushing you onto the boat’s edge.
Several beginners have felt nervous before entering the water. That is normal, and the team’s approach is built around steady reassurance. Andrea is described as patient and clear, with frequent checks once people are below the surface. A nervous member of your group may receive extra help, while a more confident participant can receive a little more independence once comfortable.
This is best understood as an introductory scuba experience, not a certification course. It gives you a first taste of moving underwater with a tank and seeing marine life at close range. The activity also suits people with prior experience, but experienced divers may find the guided format and relatively short schedule less demanding than a dedicated scuba day.

Exploring the lava seabed

The underwater route is the heart of the outing. You follow the guide through volcanic formations and along sections of white sand. The contrast between pale sand and dark basalt makes the seabed easy to read, while the cracks and overhangs create places for marine life to hide.
The guide can point out schools of fish, young fish in nursery areas, and animals that are easy to miss. Bream are among the species you might see. Octopus are another highlight, often blending into rocky spaces. Sponges and gorgonians add texture to the rock, and some outings have included starfish and bright crabs.
Do not expect a tropical aquarium. The attraction is the local Mediterranean environment, with its dark lava, modest colors, and creatures adapted to the rock. The pleasure comes from spotting life that is already there, not from being surrounded by theatrical displays.
The volcanic formations are also worth your attention. Basalt columns, lava pillows, and rope-like flows show how molten rock cooled and hardened. Underwater canyons and faults make the route feel more varied than a simple swim over open sand.
How the experience works for beginners

This outing has a strong record as a first scuba experience, largely because the instructors keep close watch and explain each step clearly. You receive support before entering the water, during the descent, and while moving across the seabed.
If you are not a strong swimmer, you should be honest with the team before starting. People with little swimming confidence have still found the close supervision reassuring, but you need to follow the instructor’s directions carefully and tell them if you feel uncomfortable.
The underwater checks are frequent. Guides watch your breathing and comfort, use signals to make sure everything is fine, and remain available if you panic or need help. That makes the activity less intimidating than an independent rental experience.
You may also have a short period to settle in before moving farther. The aim is not to test how fast you can descend. It is to help you breathe normally, control your movements, and notice the seabed around you.
What experienced divers should expect

If you already have scuba experience, you will probably appreciate the volcanic formations and the local marine biology more than the training. The guide can tailor the outing to your comfort and experience, but the trip remains a guided, recreational session.
The underwater period has been described as around 30 minutes by one participant, while the overall activity lasts 3.5 hours according to the booking information. The exact underwater time can depend on conditions, group needs, and the day’s plan. If you want a long bottom time or a more technical route, ask the operator before booking.
Experienced divers may also prefer to use the boat ride as a chance to see the coastline and learn about the area. The trip is not designed as a serious expedition. It is a compact way to combine a boat outing, marine interpretation, and a first or gentle return to scuba.
Weather, jellyfish, and changing plans

Sea conditions matter. One outing was moved to a different location after jellyfish made the original afternoon plan unsuitable. The team offered a boat trip instead and suggested returning the following morning, when conditions were safer.
That example is useful because it shows the trade-off with a sea-based activity. You cannot control visibility, currents, wildlife, or jellyfish. A flexible schedule helps, particularly if this is one of the most important activities during your stay.
The team’s willingness to change the plan for safety is a good sign. You should not pressure an instructor to enter poor conditions simply because you have limited time. If you have only one available morning, keep the cancellation terms in mind: you can cancel up to 24 hours ahead for a full refund.
Is $82 a fair price?

At $82 per person, the cost is reasonable for a half-day outing that includes a professional guide and scuba equipment. You are paying for instruction, boat access, supervision, and a guided look at a protected marine area, not just for equipment rental.
The value is strongest for beginners. A first scuba session can be stressful when you must organize gear, find a suitable site, and manage the safety side alone. Here, those responsibilities are handled by the team, and the marine biologist adds a learning element.
For experienced divers, the calculation is different. If your priority is maximum time underwater, you may find the cost less attractive than a full scuba excursion. If you want an easy coastal outing with volcanic geology and marine life, the price remains fair.
Remember to budget for your own transport to Etna & Sea Excursions. Hotel pickup and drop-off are not included.
Who should book this Catania scuba outing?

I would recommend it most strongly to first-timers, couples, families with older children who meet the operator’s requirements, and anyone curious about scuba but not ready for a full course. The steady instruction and close supervision make it a friendly starting point.
It also suits a mixed group. One person can take part in scuba while another may snorkel, depending on the day’s arrangements and the team’s approval. People who prefer a relaxed pace will enjoy the boat ride and marine explanation as much as the time below the surface.
This is not suitable for pregnant women or people with heart problems or high blood pressure. If you have a medical concern, check with a qualified medical professional before booking.
Should you book it?
Book this tour if you want a safe, guided introduction to scuba in a distinctly Sicilian setting. The best reasons are the volcanic seabed, Andrea and the team’s patient instruction, and the chance to spot animals such as octopus, starfish, crabs, and bream in their natural surroundings.
Think twice if you want a long, technical scuba session or need a fixed schedule with no chance of weather changes. For most visitors, though, this is a well-priced way to get below the Gulf of Catania and see a side of the Cyclopean Isles that you cannot experience from shore.
