The first and perhaps most important DIVE SITE in Kythnos is "Agios Sostis".
It is not only one of the most beautiful places on the island, but also a cove with at least 7 different dive sites.
The first dive site is the “Northern Inner Wall”. A dive suitable for divers of all levels, a wall that begins at the surface, very close to the beach and heads east, reaching a depth of approx. 30 meters.
Plenty small fish and the beautiful scenery characterize this wall. The countless colors hiding between the rocks require a torch to show up. Deeper we will see small dusky groupers, and a few Mediterranean morays.
In the shallow, we will see red mullets, white breams and big schools of damselfish. The huge spirographs and the pretty seastars are also noteworthy. The most observant of you will also see octopuses, corals, common soles, pipefish and many more.
If we continue eastwards and turn left just before the end of the wall, at a depth of about 30m. we come to another step that marks the next dive site, the famous by now …. “Abyss”.
At that point the wall turns to the north and vanishes at 84+ meters. A magnificent hanging balcony emerges at 32 meters where human constructions that nature has assimilated with its incomparable powers are dangling. Ropes, fishing nets and fishing lines supplement the picture that only really experienced divers will be lucky to see. At 40 meters a steep cliff with negative gradient begins, which is full of abundant colors, sponges, corals and plants that are impossible to describe. This balcony ends at about 50 meters where the wall continues straight to the abyss. Down there marine life is naturally the expected one. Huge dusky groupers and giant groupers weighing tenths of kilos, and morays of sizes only few have come across. In our return to shallower waters we meet a huge red sponge. Our friend “Gogo” (a dusky grouper) perhaps is hanging out there too.
Moving northwards along the wall and remaining at shallower waters we can take a course along the “Outer Wall”, where the third dive site starts.
There are usually strong currents against our course to the north. Our depth may range from 10-22 meters. There are no colors here but there are large schools of fish. This is where we will see big white breams and schools of saddled breams. Don't be taken by surprise if several small fish swim furiously after you! They are get used to divers. Here you will often meet large pelagics like yellowtail amberjacks and northern bluefin tuna.
Returning to the inner part of the cove we reach a spot suitable for experienced divers who seek truly rare scenery.
“The Crater”. Starting from 6 meters and moving along the “posidonia algae” seagrass we come across a literally unique picture. An almost cyclical crater is in the middle of nowhere at 35 meters deep. A small moray lives there and a local octopus often plays with a cooking pot. We ascend towards the northern side to reach the inner wall after several minutes.
If we move eastwards we get to the steps that lead off Agios Sostis, and another dive site, Mimi's Place.
The first step is from 18-25 meters, the second from 35 meters to … Dusky and golden groupers at their best. A dive for the experienced, with plenty lobsters and wonderful scenery.
But Agios Sostis is not only about deep diving.
The “South Wall”, at a depth of 5-22 meters, has many fish and a very nice and colorful seascape and of course the beach where novice divers and students enjoy their first experience in the shallow, in the company of wrasses, breams, common soles, red mullets and often cuttle fish and schools of damselfish.
“Vouvoxera” (Silent Reef) is our pride and joy, a reef swarming with life. Weather permitting, divers of all levels can enjoy phenomenal experiences. The number of fish is infinite. Black, white, red and all kinds of color, size and type are here. Big dusky and golden groupers prevail in the northern side “The Temple”, and among the amphora the colors of our sea. Rays, saddled breams, and others as we head south, towards the great single rock. We then start to ascend and wander among plenty of pearly razorfish, scorpion fish, young dusky groupers and big triton shells. At least three dives are possible in
The northern and deeper side, the east, and the south side with the great drop-offs and the groupers. While diving here we should not forget to look up. Only then will we be able to realize nature's grandeur and how lucky we are to be here.
Words are really unnecessary.
To the north of Loutra and before we reach “Katakefalo” there is a less protected site, the “Mamakou cove”. We dive at the southern “Lobster reef”, where the name speaks for itself.
A dive for all levels and, weather permitting, sufficient marine life, lobsters, Mediterranean morays and often rays.
“Potamia” (Rivers) are closer to Loutra. There are three dive sites here for divers of all levels. Our “swimming pool”, as the name suggests, is ideal for courses and discover scuba sessions at depths down to 12 meters.
The “Agios Sarantis wall”, where the depth changes gradually and reaches 45 meters. Here we will see everything! Octopus, countless nudibranches and a lot of small fish in the shallow, Mediterranean morays and golden groupers further down, remains of amphora and young dusky groupers among them, until we reach the lobster wall later on. Major points of interest are the rock in the shape of a heart, the curved up rock, the house of dusky groupers and of course the lobster wall.
On the opposite side we have “Mikra Potamia” (Little Rivers) and a shallow wall for a calm and enjoyable dive or courses.
At the north of the Potamia we will find “Ypovrichio” (Submarine). A rock which really reminds you of a submarine, with the typical long cylindrical shape and turret. A beautiful dive for all levels and many surprises. Technical divers will have a chance to see the submarine anchor deeper. This is a real anchor of vast dimensions at 54 meters, surrounded by the indescribable.
Moving further north we come to the dive site “Babakou”. A pyramid- shaped reef suitable for an easy multiple level dive and an interesting bottom. In the blue waters we might often meet big pelagics.
The dive at “Katakefalos” (North n Wild) is a difficult dive, due to the weather. If the weather helps, don't miss the chance.
Incredible rock formations, a variety of fish and many surprises, at a site where the weather plays the major role. Note that the biggest waves of the Aegean Sea have been recorded at Cape Kefalos, where this dive takes place.
The last and furthest dive in the northern part of the island is “Glyfada”. A wonderful reef with a mild or at times stronger current. Big fish swim everywhere here, but it's the seascape that attracts your attention. Rock formations such as “The Gate”, “The Canyon”, corals at the “Coral Garden” and many more...
Close to Loutra there is a dive site which is suitable for diving both from the beach and a boat. “The Love Reef” is a nice reef with different routes and a lot of marine life. Everything is possible here, but you will definitely find yourself among jars and small creatures.
“The Bridge “accommodates most of our night dives or day dives from the beach. What can be found here cannot be described. From small treasures to lonely crabs, octopuses and other interesting stuff. Diving at the Bridge is always fascinating.
Those are only several of our dive sites.
More dive sites closer of further are awaiting for you to discover.
Starting from the North just 10 minutes boat ride from our dive center we have:
The stairway and Scout’s are two very beautiful sites for all certification levels.
On the way to South:
Agia Irene’s lighthouse with many remains of ancient wrecks and diversity of subaquatic life.Another place is The Cross, a deep vertical wall, that offers at least 4 different dives. One in The Wall, one it The North Reef, the South Wall and the Deep Reef.
Even southern we have:
The Small and the Great Lagoon, Ai Lias’ reef, No Name Reef, the Shoe's Wreck.
On the East coast of the island Poseidon's Gardens and Vathy Avlaki and on the SouthEast of the island:
The Gun, The Airplane, Pirate's Cave, Pepe Michalis Wreck and Spaleta's Caves.
Kythnos island has countless beauties and the see is full of magic landscapes and rich in underwater life.
What you have to do, just relax discover and enjoy
