Santorini Beaches: Every Beach, Ranked and Explained

A volcano made these beaches

Santorini is the rim of a flooded volcanic caldera. The Minoan eruption of circa 1600 BC blew the centre out of the island and buried the Bronze Age town of Akrotiri, which you can still walk through today. Everything east and south of the caldera rim is volcanic rock, and the beaches are made of it. Waves and time grind the black lava into the dark grains you walk on at Perissa and Kamari.

This is why there is no natural white-sand beach on the island. The colour comes from the ground itself, not from algae or pollution. On the caldera side, where the cliffs drop straight into deep water, there are few beaches at all, which is why swimmers there use boat platforms, rock ledges at Ammoudi and the harbour at Fira's Old Port.

• Black sand heats up fast in the sun. Shoes are worth packing.
• The sand is coarser than imported sand. It clings less and rinses off easily.
• The same volcanism made Red Beach's iron-red cliffs and Vlychada's grey pumice.

What the black sand means for your day

Practical differences follow. Barefoot walking at noon is genuinely painful, so pack sandals or water shoes and leave them at the sunbed line. A dark towel on dark sand is easy to lose track of, so pick a bright one. The dark surface also warms the shallows quickly, which is one reason the east coast swims feel warmer than the calendar suggests.

Swimming itself is excellent. The east coast shelves gently and the water is clear, with the dark bottom making it look deep where it is not. Sunbeds and umbrellas rent by the row at Perissa, Perivolos and Kamari, and tavernas sit right behind the beach. Our pick for a first beach day is Perissa: the longest stretch, the most space, and Ancient Thera on the cliff above if you want to add a ruin to the afternoon.

Perissa and Perivolos

Perissa runs about the length of a small town along the foot of Mesa Vouno, the mountain that separates it from Kamari. The bus from Fira costs $3.02 (€2.70) and takes you to the northern end, where the tavernas are thickest. Walk south and the rows spread out until Perivolos takes over, a calmer continuation where beach clubs replace family tavernas. The water is clear, the entry is pebbly in patches, and the swell is usually gentle in the morning.

Perissa is our pick of all the Santorini beaches for a full day. You can swim, eat, rent a sunbed and climb Ancient Thera from the same spot. Ancient Thera, a Dorian city from the 9th century BC, sits on the summit above. Entry is $11.19 (€10), summer hours are 08:30-15:30 and it closes on Wednesdays, so do the ruin first and the beach after.

Kamari

Kamari sits on the other side of Mesa Vouno and trades space for convenience. A paved promenade runs the length of the beach, so pushchairs and wheelchairs manage here where Perissa's soft sand is harder work. The bus from Fira costs $2.46 (€2.20), the shortest fare of the big beaches, and the same line continues to the airport and Monolithos. Rows of sunbeds, beach bars and a long strip of Santorini restaurants make it the simplest place to organise a day.

Families choose Kamari for that reason. The promenade gives shade and stroller access, the entry is gentler than Perissa's in most spots, and everything is close. The trade-off is that it is the most crowded of the big beaches in July and August. Come before 10:00 or after 17:00 (our estimate) and you get the best of it. Between Kamari and Perissa there is no coastal path over the mountain, only the winding road up to Ancient Thera, so pick one beach per trip rather than planning to hop.

Vlychada

Vlychada is the beach that looks least Greek and most lunar. Decades of wind have sculpted the tall grey banks of volcanic ash into soft curves, towers and caves, and the sand below is a fine dark grey. A small marina sits at the south end, home to the catamarans that sail past the coast every morning, and the beach stretches north from there with fewer rows of sunbeds than Perissa or Kamari.

The bus from Fira costs $3.13 (€2.80), the priciest beach route on the island, and it is exposed. When the summer meltemi blows, Vlychada feels it first, and swimming gets choppy. Our advice: go on a calm day, take the photos early while the light is flat, then settle in the northern corner out of the wind. Catamaran passengers see these cliffs from the sea on the way out of the marina, which is a fair second option if you dislike wind.

Red Beach and White Beach

Red Beach, near Akrotiri, is a wall of deep red cliff above grey-red shingle, and it is the single most photographed shoreline on the island. It is also closed by land. The municipality has banned access because of rockfall danger, restrictions that go back years and were tightened after a rockfall following the February 2025 earthquake. Reports since describe it as reachable only by boat. Do not climb down. The official line is simple: see it from the viewpoint above or from a boat, and our Red Beach guide explains the viewpoint.

White Beach, next door, has no land access at all and never did. Both are standard stops on the south-coast catamaran route from Vlychada marina, where the boats slide close to the cliffs for photos before a swim stop. If red and white cliffs are your reason for a beach day, book a boat rather than a bus. Combine the trip with the Akrotiri archaeological site inland, whose entry is $22.40 (€20) and whose Bronze Age streets were buried by the same eruption that made these cliffs.

Ammoudi Bay

Below Oia's cliffs sits Ammoudi, a tiny red harbour where fishing boats tie up beside waterfront tavernas. Round the point to the right and you find rock platforms with ladders into deep, clear water, the best fixed-entry swimming on the caldera side. You reach it from Oia by a long staircase or by the road, and the step count is not officially published, so allow real time on the way back up in the heat.

The rhythm here is lunch, swim, sunset. Eat at the waterline, swim off the rocks in the late afternoon, then climb back up and take your place for the Santorini sunset above. Ammoudi is also a departure point for boat trips to Thirassia and the volcano, and it is one of the few places where you can swim and watch the caldera glow without ever getting on a boat.

The hot springs and the Old Port

Palea Kameni, the older volcanic islet in the middle of the caldera, holds a bay of warm, iron-rich water. Boats anchor offshore and you swim in from the side, emerging smelling faintly of sulphur and, if you wore a light swimsuit, wearing an orange stain that mostly washes out. The water temperature is not officially published, but it is noticeably warmer than the surrounding sea. Most catamaran itineraries include the stop, as does the classic volcano boat from Fira Old Port, which pairs 1.5 hours on the Nea Kameni crater trail with the springs swim. Landing on Nea Kameni carries the €5 volcano park fee, paid on the island on top of the boat ticket.

Fira's Old Port itself is a swim option of last resort: cruise tenders, the cable car and water taxis share it. The proper caldera swims are the ones above. Note that the Santorini cable car from the port up to Fira costs $11.19 (€10) one way, or you take the several hundred steps of the Karavolades path on foot.

Bus fares and routes

Fira's bus station is the hub for the whole island. To Kamari the fare is $2.46 (€2.20) and the same line continues to Monolithos beach by the airport. To Perissa and Perivolos it is $3.02 (€2.70) for the 20.4 km run down the east coast. To Vlychada it is $3.13 (€2.80), and to the Akrotiri village and beach stop it is $2.46 (€2.20), from where Red Beach's viewpoint is a walk (our estimate). Oia, for Ammoudi, costs $2.46 (€2.20) on the 11.8 km northern line.

Departure times are seasonal and only published in the KTEL PDF, so check it on the day rather than trusting a fixed timetable. Pay the conductor on board. Reduced fares of about half price apply to large families and disability, and a student discount exists. For Ammoudi specifically, remember the last stretch is the Oia staircase or road, and coming back up after dark is slower than the ride down.

When a car or boat beats the bus

The bus wins on price, but it has two limits: frequency drops in the evening, and nothing reaches White Beach or the water-level view of Red Beach, because no road does. A rental car or ATV gives you the south coast at your own pace and lets you chain Akrotiri, the lighthouse and Vlychada into one loop. Read our guide to getting around Santorini for the full picture, including why a licence valid for the engine size matters on a quad.

The third option is the boat, and for the south coast cliffs it is the only real one. Catamarans out of Vlychada pass Red Beach, White Beach and the Akrotiri lighthouse with swim stops and lunch on board. Cruise passengers moored off the Old Port can also book shore tours that include the black beach without touching the cable-car queue. If the beaches are your priority and your time is short, one boat beats three buses.

Sea temperature by month

The sea around the island rarely gets cold. Averaged over recent years, it sits around 17.8 °C in January and dips only to about 17.1 °C in February and March, then climbs steadily: about 19.3 °C in May, 22.7 °C in June, a peak of 25.9 °C in August, and still 23.1 °C in October. In practical terms, June to October is the comfortable swimming window, and hardy travellers swim into November when the water is around 21.1 °C.

Air and sea peak at different times. Air temperatures top out in July and August, but the sea is warmest into early autumn, which is why September is our pick for the best beach month of the year. The water is at its warmest, the crowds have thinned, and the Santorini weather is still reliably dry. Full month-by-month figures are in our sea temperature guide.

Wind, waves and the meltemi

The thing that actually ends beach days here is not cold, it is wind. Mean daily maximum winds run 28-37 km/h all year, and in July and August the summer meltemi blows hard across the Aegean. On the east coast the black-sand beaches take it on the nose, sand flies, and umbrellas strain. On the exposed south coast, Vlychada gets choppy. Boat trips are the most affected of all, and operators' weather clauses allow cancellations when conditions turn.

Practical responses: in high summer, swim in the morning when the wind is usually lighter, pick the northern corner at Vlychada, and book boats early in your stay so a weather cancellation can be rebooked. If a boat day is cancelled, the caldera-side rock swim at Ammoudi, which is sheltered by Oia's cliffs, is a decent fallback (our estimate). See the best time to visit Santorini for how this plays out across the year.

Our picks by traveller

Families: Kamari. The promenade, the shortest bus fare at $2.46 (€2.20), gentle entry and food within sight of the water make it the lowest-effort day. Swimmers and couples: Perissa, for length, clear water and the option to climb Ancient Thera afterwards. Photographers: Vlychada for its carved grey cliffs, with Red Beach's viewpoint a close second. Anyone on a cruise or a short stay: the boat. One catamaran passes more colour in five hours than two days of buses.

What is the single nicest beach in Santorini? Our answer is Perissa, and it is not close. It combines the longest swim-friendly stretch, real infrastructure and a headline ruin on the cliff above. Vlychada is more beautiful and Kamari more convenient, but Perissa is the one we would send a first-time visitor to. If you only have one day on the island, our one-day itinerary shows how to fit a beach hour in.

Pairing beaches with the rest of the island

Beaches work best as one half of a day. Perissa pairs with Ancient Thera above it, whose summer entry is 08:30-15:30 and closed Wednesdays, so climb first, swim after. Kamari pairs with the same ruin from its side, or with a morning at the airport-adjacent Monolithos if you have a late flight. The south coast trio of Akrotiri, Red Beach's viewpoint and Vlychada makes a natural loop by car, ending at the Akrotiri lighthouse for sunset.

On the caldera side, Ammoudi slots into any Oia afternoon: bus over, lunch on the water, swim off the rocks, climb up for sunset. And if you would rather see the beaches without choosing, the full-day group tour that includes a beach stop plus the villages and the Oia sunset does the stitching for you.
