Scoglio Grosso

Thisrockunmistakablefor its shapewith two points,is the northernmostamong therocky outcropsnorthof Ponza,after Gavi, theScoglitelleandPianadi Mezzo.It risesin the directionof Zannoneand is clearly visibleeven from a distance, especially whenthefoamingwavescrashing against. Thanks to thediversifiedconfigurationof therockyseabed, there are different typesof divesdepending on the experienceof divers.

As a rulegivesthe anchorin front ofthe rockabout 30 metersaway,inthe south-east, where you can see thetop of abankthatrises up to3metersbelow the surface.Thesuggested itinerariesarebasically two, and both have asstart / end,thetop of the bank in 3meters.

The firstleadson the north-west of ScoglioGrosso.Descending from thetop of the bank towardthe north, flying over asloping bottomstoneswithpatches ofsea grass, we reach a stunning drop off, which is locatedat a depthbetween 25 and37 meters. Themost significantmorphological elementconsists of a natural arch passage, richlydecorated with theclassicMediterraneansessileforms. To reach it,keeping the wallon the left, you pass through a tunnelwith double openingand at the exit, go right until you find outthe Arch. In the shadows, the eye fallseasilyon variousspecies of crustaceans: theSlipper Lobster(Scyllarus arctus), theBlack Squat Lobster (Galathea squamifera), theSleepy Crab(Dromia personata), the Spider Crab(Lissa chiragra), Stenopus Spinosus (Shrimp), but obviously thevariety oflife formsis highlydiversifiedandcovers everysystematic group, from algae tofish. Keeping the wallto the leftuntil youreach,around10-13meters, a narrow passagebetween tworock wallsfullycovered withYellow Cluster Anemone (Parazoanthus axinellae).


Regarding thesecond itinerary, starting from the mooring pointwe proceedin a southerly directionuntil you reach thedrop offthatgoesfrom 25to 42meters, with plenty of hiding placesand longcracks. On thissidethere is a cavepassingat 38m,further evidenceof the variability ofmorphology. In this part ofseabedis notdifficult to seelobsters(Palinurus elephas) and several speciesofreeffish: among the moststriking, there are moray eels(Muraena helena) andconger eels(Conger conger), and a beautifulwrasse(Labrus bimaculatus) thatchangesexfrom female to male, when they exceed24-28centimeters,they both haveflashycolorsandwell differentiated. As thewater heats,begin to appeargroupers(Epinephelusguaza) and Golden Groupers(Epinephelusalexandrinus). In shaded areas, we find largeorange sponges, encrusting violet algaeandevensea anemones,tunicates,fakecoral.Youcan seeseveralexamples ofsea stars(Hacelia attenuata), and the even morewidespreadpurpleseastar(Ophidiaster ophidianus), sometimes spottedwithorange, attracted by thesubstratesexposed todirect sunlight.

In this areaof seabed, located offshore, and oftenexposedtostrong current, theoverall impression is thatof beingin a particular place, where you can expectanysurprise,thereforefrom time to timehave a look in the bluefor special sights.Forfurtherinformation, let's add, thaton the sand, 45 m deep,in the outside of thewall, there is a groupof wonderfulmonolithsrich in color,butfor the depthand distance,we recommend the useofan underwater veichleorplan a specificdive.
