Santorini diving is volcanic diving: black lava walls, the caldera face, sulphur vents at Palia Kameni and the Taxiarchis wreck, in water of 17 to 25 degrees with 20 to 30 metres of visibility. The season runs April to November, a two-tank boat dive costs 90 to 140 euros, and June and September are the best months.

Perhaps the most special island of the Cyclades is Santorini, or Thira for those who prefer it. There are 9 beaches you should swim in Santorini 2023 and you can visit them with Santorini Tours. Its beauties are infinite and famous enough: the volcano, the sunset, the white houses, the view from the caldera make up a scene that attracts visitors from all over the world like a magnet!
The beaches of Santorini are truly unique due to the peculiar geological landscape that in contact with the sea becomes even more impressive. The special waters of the volcano and the recently formed complex seabed create, in combination with the colorful rocks of the land, an almost out of this world scenery.
1. Red Beach
Let’s start from the most famous beach of the island located at the southern end of the island, the legendary Red Beach. Its immense fame no doubt also reflects its insurmountable beauty, an explosive combination of red and black rocks, dark blue crystal waters, red sand alternating with black pebbles and underwater hot springs. It is relatively small so it is usually full of people.
Don’t forget to take the appropriate sun and heat protection with you, as the temperature here is usually higher than the rest of the island. Among its disadvantages is the access ban issued by the authorities due to landslides, which is why those who visit it do so at their own risk.
2. White Beach
Very close to Red Beach is White Beach. It is a welcoming cove surrounded by tall, white cliffs, with black sand mixed with white pebbles and crystal clear waters. Its special feature is its white color which contrasts with the dark or reddish colors found on the rest of the beaches of the island.
Here you will find a canteen to get the necessary supplies. Do not miss under any circumstances to visit the nearby archaeological site of Akrotiri, one of the most important prehistoric settlements of the Aegean that was buried under the ash of the Thera volcano.
3. Vlychada beach
At the southernmost tip of the island is Vlychada, a long beach with characteristic yellowish rocks and caves that have been carved by time and waves. The coast has fine black sand and dark pebbles. Here you will find umbrellas and a picturesque beach bar built into the rocks, while above the harbor where small boats are moored there are taverns for food.
4. Kamari beach
A little further north, under the Mesa Vounos where the ancient Thera was built, is Kamari, the rival awe of Perissa. It brings together some of the most typical characteristics of Santorini beaches: black sand with pebbles, wonderfully clear and deep waters, cafes, taverns, clubs, mini markets, tourist offices, etc. Despite the crowds, Kamari remains one of the largest and most charming beaches in island.
5. Monolithos beach
We remain on the eastern coastline, where a little north of Kamari we will meet Monolithos. It is a beautiful beach with black sand – no pebbles this time – and relatively shallow waters, a true paradise for family outings. It also has all the amenities, taverns, cafes, hotels, mini markets and everything a bather could need.
6. Exo Gialos beach
Very close to Monolithos, after passing the village of Karterados, you will come across Exo Gialos, a coast with black fine pebbles, dark blue waters and tamarisk trees, a not so common feature of Santorini. It is organized and sometimes very secular and noisy, with often large parties that vibrate the area.
7. Columbus Beach
Approaching the northern part of the island, near Oia, you will find a beach different from the classic, tourist beaches of the island. It is Columbus, a secluded and wild beach in a lunar landscape of incomparable beauty. To the right of the coast, in the Seal Cave as it is called, there is also an underwater active volcano. The beach is a favorite choice for nudists and adventurous types.
8. Ammoudi beach
Passing by the beaches of the western coastline facing the caldera, we come across Amoudi, right at the port of Oia. It is a small cove with a wonderful view towards Thirasia, with rocks and steep, deep water, suitable for skilled swimmers. You will reach it if you go down the 214 steps from the famous Oia with the even more famous sunset. You can take a tour of Santorini!
9. Beaches in Thirasia
Opposite Santorini is the small island of Thirasia, a remnant of the prehistoric island of Strongyli that sank after the eruption of the volcano around 1600 BC. and created the caldera. Thirasia generally has small and steep beaches, the crystal clear waters and their magnificent view make swimming in them an unforgettable experience. For those who visit there is the Black Beach near the port of Riva, as well as the beach in the small port of Corfu with pebbles and pumice stones.

Santorini Diving: The Short Answer
Santorini diving is volcanic diving: black walls, lava arches, a sunken caldera floor and water that stays 18 to 25 degrees depending on the month. It is not a coral destination and nobody comes here for the fish. What it offers is underwater geology no other Greek island can show you, plus a couple of wrecks and very good visibility.
The santorini diving season runs April to November, most dive centres are based at Vlychada, Perissa or the caldera side, and a two-tank boat dive costs roughly 90 to 140 euros. Discover Scuba sessions for beginners run 70 to 110, and full PADI Open Water courses 400 to 500.
Visibility on santorini diving trips is typically 20 to 30 metres, and the caldera itself drops to nearly 400 metres, so almost all santorini diving happens along the walls and the shallower coastal sites rather than out in the middle.
The Main Dive Sites
Palia Kameni. The old volcanic islet, with black rock walls, warm-water vents and the yellow-orange staining of sulphur on the stone. The signature site of santorini diving.
Nea Kameni. The other volcanic santorini diving site: lava formations, dramatic drop-offs and the occasional warm current rising from the seabed.
The Caldera Wall. The most dramatic santorini diving site of all: a near-vertical volcanic face falling away below you, and the closest thing here to flying.
The Taxiarchis wreck. A cargo ship at around 18 to 40 metres off the south coast, broken but intact enough to be interesting, and the best wreck for santorini diving at recreational depth.
Adiavatos reef. Rocky reef with swim-throughs and good numbers of fish by local standards.
Indian Rock and the south coast sites. The santorini diving fallback when the meltemi is blowing, and the sites most used in July and August.
The hot springs area. Shallow, warm, strange, and better snorkelled than dived.
What You Will Actually See
Geology, which is the point of santorini diving. Black lava, pumice banks, vertical walls and volcanic vents. This is the reason to dive here.
Fish. Modest. Damselfish, breams, groupers, octopus, moray eels and the occasional barracuda. The Aegean is not the Red Sea and santorini diving is honest about that.
Visibility. Usually 20 to 30 metres, and among the better visibility in Greece because there is almost no river runoff.
Water temperature for santorini diving. 17 to 18 degrees in April, 22 to 24 in July, 24 to 25 in September, and around 20 in November. A 5mm wetsuit covers the season.
Depths. Most recreational santorini diving sits between 10 and 30 metres. The caldera floor is far beyond any recreational limit.
Currents. Generally mild, and the wind matters far more than the current when a dive is called off.
Practical Details
Santorini diving season. April to November, with the best conditions from late May to early October.
Where the centres are. Vlychada, Perissa and the caldera side, most running two-tank morning boat trips.
Cost of santorini diving. 90 to 140 for a two-tank boat dive with equipment, 70 to 110 for a Discover Scuba session, 400 to 500 for a PADI Open Water course over three or four days.
Certification. Bring your card and your logbook. Most centres will ask when you last dived and will insist on a check dive after a long gap.
Beginners. Discover Scuba runs from a boat or a shore site in shallow water, and santorini diving is a perfectly good place to try it for the first time.
Snorkelling. Cheaper and genuinely worthwhile at the hot springs and along the south coast, with the same volcanic scenery in the first few metres.
Booking santorini diving. A few days ahead in the shoulder months and a week or more in July and August.
Flying. Leave at least 18 to 24 hours between your last dive and your flight home, which on a short trip means diving early in the week.
When to Dive and What Can Stop You
The meltemi. The strong northerly of July and August is the main reason a day of santorini diving is cancelled. The south coast sites stay workable when the north is not.
Best months for santorini diving. June and September: warm water, calm mornings and full schedules.
Worst months. December to March, when most centres close and the sea drops to 16 or 17 degrees.
Mornings. Almost all boats leave between eight and ten, which fits neatly around everything else on the island.
How it fits a week. Half a day, so it slots into the same slot a catamaran would take, and you keep the afternoon. Do not book santorini diving on the same day as a boat tour or a long walk.
Where to stay for it. Perissa, Perivolos or Vlychada put you within ten minutes of most dive centres, and they are the cheaper places to sleep anyway. See where to stay.
