A protected Marine Park, Portofino is renowned for offering the best diving in Italy for all levels of experience; reefs, walls and shipwrecks are surrounded by big snappers, damselfish, sea bass, sea bream and moray eels. In certain locations you will find lobster, tuna, sun fish, octopus, coral fans and rare black coral branches. Due to the abundance of marine life, it’s not uncommon to see both whales and dolphins in the park. Another favourite site in Portofino Marine Park is Christ of the Abyss, the original of the famous sculpture which can be found in the small bay of San Fruttuoso.
As either a recreational or technical diver, you will have an abundance of choice in Portofino Marine Park.
These dive sites differ in topography and depths (there are plateaus, pinnacles, steep walls and overheads) as well as they have the greatest biodiversity in the whole Mediterranean Sea. In particular, you will get to observe many big groupers, snappers, barracudas and beautiful coral reefs.

Shore dives in Portofino Marine Park by car:

We also provide service diving by car. Our pick up is ideal and designed for scuba diving equipment safe transportation. That give us the flexibility to have always a near by entry-exit option in case of bad weather, if number of divers do not make affordable a long transfer by boat or simply to explore areas not accessible by boat.

In the area there are many interesting wrecks, full of history, where you could dive in Tech Configuration!!!

Most of those wrecks are in perfect navigation trim and in really good conditions and a good number of them are OK for a nitrox use as bottom gas so ideal for advanced recreational or entry technical training dives or either to get familiar with this area.
Those are many different wrecks from the 1st and 2nd World war which have now turned in an amazing nurse for many species of fish, anemones and corals.
The Haven, the biggest wreck in the Mediterranean Sea, takes about 45 minutes navigation from “Il Grande Blu”.

A shallow, ancient artificial reef developing towards East in confined open waters area became an amazing nursery for bait fish, breams; small creatures, cray fish, octopuses sponges and especially loads of nudibranchs, which all together makes it an incredible night dive.
It is not uncommon coming across with eagle rays, sting rays, predators like tunas, barracudas, groupers, marlins and dolphins during day time.
A line connection to Motozzattera Wreck (35 mt deep) is easily reachable by scooter for DPV, wreck or technical dives and exploration.

Before you start your preparation we highly recommend to have a proper orientation of the dive site even though it is really an easy and safe environment where you can have training or non-guided exploration. An underwater map of this area is available by the reception or below.

An off shore dive is directly reachable and ideal for confined water training sessions only a few meters away from the classroom and so from the entire facility. That is what makes of Il Grande Blu the ultimate spot for training. You will actually take full advantage of your time that you are investing as a student or as a trainer as there is NO time waist due to transfers to the dive site or to the bar-restaurant or to the classroom.

Dedicate your morning to your water sessions, lunch to your debriefing and feed backs then finally your afternoon to classroom session without having tiring and long days is reality here at IGB.

Entry – exit is ideal also for CCR, side mount, stage cylinders, DPV courses, or whatever else configurations.

Free divers have the perfect place for shallow training session as the confined open waters area quickly slopes to 18-20 mt on cable or DPV, but also in the shallow part they can easily practice static apnea sessions, breathing techniques, relaxation and yoga.

In the confined open waters area you will find an artificial underwater “gym”, ideal for fundamental and advanced levels to practice buoyancy & propulsion drills, a flat platform for emergency and safety drills and tie off to practice reeling during overhead protocols courses.

A submerged webcam and an Underwater wireless communication system provided by Ocean Reef might also be used from the surface as an observatory, supervision or training tool.
We also provide a wide flat screen TV in the classroom where students can observe themselves during their performance, by only connecting a video or photo camera.

Come and see how your learning curve can improve by this!

Handy tips:
Make sure you know the difference between a boat launch & board lane, confined waters area and confined open waters area, where they are located on the maps and how to best navigate underwater to find the way out and the way back to the entry point.
Even though boats are not allowed in the line marked area – especially from May till September – due to international laws (http://www.guardiacostiera.gov.it/en) you must always dive safely by carrying a dive buoy (with flag incorporated) and stay within 50 mt on a circular line from it. In any circumstances, boats will have to navigate at least 100 mt away from it on a circular line.
Il Grande Blu will provide you one in case you don’t have it with you.

Try to avoid ascents to surface (unless an emergency occurs) in the moment you hear an engine noise close by; if you practice ascents to surface from deeper waters, do so next by an ascent line given by your dive buoy or your surface maker buoy and learn first how you reach back to shore, so only once you are familiar with this area or by using natural reference (current, sun, wind or terrestrial formations) and your navigation compass.
Mind the surge and tides! Feel free to ask to our staff the best entry point or technique in case you find Southern winds making the sea choppy.
Keep refreshed your rescue skills, respect the rule of thirds if you dive on DPV and stay within your bail out limits considering the total linear distance from the shore when you dive on CCR.
