Santorini Beaches
Quick answer
Santorini’s beaches are volcanic. Lava and basalt eroded over thousands of years into dark grey and black sand, which is why a Santorini black sand beach looks nothing like a pale Mediterranean shore. The main ones are Perissa, Perivolos, Kamari, Vlychada, Monolithos and Exo Gialos, all on the south and east coasts. Perissa and Perivolos form the longest continuous stretch, Kamari is the most organised, and Vlychada is the most dramatic. Dark sand absorbs heat quickly, so bring water shoes in summer. Every beach in Greece is free to access; you pay only for sunbeds and umbrellas.
Red, Black, and Volcanic Shores Worth Exploring
Santorini’s beaches look different because the island formed through a massive volcanic eruption. That same history created coves, sea caves, and dramatic coastlines, along with beaches shaped in red, white, and black tones.
Each beach offers its own atmosphere. Some feel iconic and dramatic, others feel calm and practical for an easy swim.

Exo Gialos Beach (Karterados Beach)
Exo Gialos, also known as Karterados Beach, is black sand and pebbles directly below Karterados, about ten minutes from Fira. The quietest swim near the caldera villages.
Red Beach
Red Beach sits beside Akrotiri, with deep red cliffs and sand that make it the island’s most photographed shore. Access depends on rockfall conditions, so check before you go.
Perissa Beach (Black Beach)
Perissa is the best-known black sand beach, beneath Mesa Vouno, with the most facilities on the island. Fine sand and a lively strip of bars and tavernas.
Vlychada Beach
Vlychada is grey sand under pale cliffs carved by wind and rain, and it is usually the calmer choice when the meltemi blows.
Monolithos Beach
Monolithos has shallow, calm water a long way out and sits close to the airport. The family choice.
Kamari Beach
Kamari is smooth black pebbles and the island’s tidiest promenade, on the other side of Mesa Vouno from Perissa.
Stay Close to the Volcanic Coast
Karterados sits between Fira and the island’s eastern beaches, which makes it a practical base for beach days without the caldera-edge crowds. Emerald Collection Suites is a short drive from Monolithos, Kamari and Exo Gialos.
Why Santorini's Sand Is Black
Santorini is the rim of a collapsed volcano, and its beaches are made of ground-down basalt, pumice and lava rather than pale quartz and shell. That is why the sand runs from charcoal grey to near black, and why the grain changes from fine sand at Perissa to smooth pebbles at Kamari. Our guide to Santorini’s black sand beaches explains where the colour comes from and how each beach differs.
Kamari or Perissa? How to Choose
The two most compared beaches sit on opposite sides of Mesa Vouno, about 20 minutes apart by road. Perissa has fine black sand and the most facilities; Kamari has smooth black pebbles and the island’s tidiest promenade. See the side-by-side comparison in our black sand beaches guide.
What Black Sand Is Like Underfoot
Dark volcanic sand absorbs heat, and by midday in July it can be too hot to cross barefoot. Bring sandals or water shoes and a thicker towel. Our black sand beaches guide covers what to pack and how the water differs from beach to beach.
Getting to the Black Sand Beaches
The dark beaches sit on the opposite side of the island from the caldera villages, so nearly everyone drives, rides or takes the bus. Buses run from Fira to Kamari, Perissa and Perivolos through the summer, and beach parking fills by late morning in August. For routes, drive times and transfers, see our guide to getting around Santorini from Karterados.
When to Go
The sea is swimmable from roughly June to October. Which month you choose changes the crowds, the heat of the sand and the wind more than the water itself.
June and September
The sweet spot. The sea is warm, the beaches are open, and the crowds are thinner than midsummer.
July and August
The strongest heat and the busiest sand. Black beaches feel hotter than pale ones, so plan around the middle of the day.
May and October
Quieter and cooler. Many beach clubs run reduced hours or close, so check before you rely on facilities.
Watch the wind
The meltemi blows through summer and hits the east coast hardest. On gusty days Vlychada and the south coast are usually calmer.
Practical Details
A few things worth knowing before you go.
- Access is free. Greek law keeps the shoreline public. You pay only for sunbeds, umbrellas and service.
- Sunbed costs vary. Expect roughly 15 to 40 euros for a pair with an umbrella, higher at beach clubs in Perivolos.
- Facilities are seasonal. Showers, changing rooms and lifeguards run mainly from June to September.
- Take the sand seriously. Reflected heat and glare from dark sand increase sun exposure, so reapply sunscreen more often than you would elsewhere.
Frequently Asked Questions
Why are Santorini's beaches black?
Santorini is an active volcano, and its beaches are made from eroded volcanic rock. Lava, basalt and pumice from eruptions, including the major one around 1600 BC, broke down over millennia into dark grey and black sand.
Which is the best black sand beach in Santorini?
Perissa is the best known and has the most facilities. Kamari offers a tidier promenade and coarser pebbled sand. Vlychada is the most dramatic, set against wind-carved white cliffs. Monolithos is the best choice for families because the water stays shallow and calm.
Are Santorini's beaches sandy or rocky?
Both. Perissa, Perivolos and Vlychada are genuinely sandy, though the grains are dark and coarser than white sand. Kamari is closer to smooth black pebbles. Exo Gialos and several smaller coves are rockier.
Are Santorini beaches free?
Yes. Greek law keeps every shoreline publicly accessible, so walking on and swimming from any beach costs nothing. You pay only for sunbeds, umbrellas and service, typically 15 to 40 euros for a pair with an umbrella.
Is black sand hot to walk on?
Yes, noticeably. Dark volcanic sand absorbs much more solar heat than pale sand and can become too hot for bare feet by midday in July and August. Water shoes solve the problem.
What is the difference between Kamari and Perissa?
They sit on opposite sides of Mesa Vouno. Kamari has coarser pebbled sand, a paved promenade and a quieter feel. Perissa has finer black sand and a livelier atmosphere. The drive between them takes about 20 minutes.
Is there pink sand in Santorini?
Not truly. Travellers searching for pink sand are usually thinking of Red Beach near Akrotiri, where iron-rich cliffs and sand can appear rose-coloured in soft light.
