When you think of a white sand beach Santorini, you might picture powdery shores stretching beneath dramatic cliffs—but Santorini defies the ordinary. This captivating Greek island is not just about its iconic blue-domed churches or dreamy caldera sunsets. Its shores tell a different story—one shaped by fire, ash, and time. From jet-black volcanic sands to rust-red cliffs plunging into cobalt seas, Santorini beaches are a vibrant mosaic of nature’s boldest palettes. And while they may not resemble the typical Aegean postcard, their raw, elemental beauty is unforgettable. Whether you’re chasing romance, adventure, or serenity, exploring the best beaches in Santorini will show you a wilder, more unexpected side of this island paradise.
1. Vlychada
Tucked beneath towering pumice cliffs sculpted by time and wind, Vlychada is one of the most surreal stops along the Santorini beaches trail. Its long stretch of grey-white pebbles and lunar landscape creates a dreamy, off-the-map vibe that draws artists, adventurers, and sun-chasers alike. You can unwind at the mellow Theros Wave bar, find your own private patch of shore, or dip into the island’s best seafood at To Psaraki by the harbour.
For those with a free spirit, the far end of the beach is known for nude sunbathing and skinny-dipping. Just behind the beach, the Santorini Arts Factory surprises with its fusion of industrial charm and modern creativity. Stay nearby at Sea Breeze Santorini by Hilton Curio Collection—where bamboo-accented suites, a breezy beachside restaurant, and sweeping sea views complete the experience of exploring the most striking of Santorini beaches.
2. White Sand Beach Santorini
White Beach, or Lefki Ammos as locals call it, is one of Santorini’s most secluded and visually striking coves. Despite the name, the beach isn’t covered in white sand, but rather black pebbles and grey volcanic sand framed by towering chalk-white cliffs. This dramatic contrast is what makes it so captivating. The beach is tiny, offering only a handful of sunbeds and umbrellas, so come prepared with water, snacks, and sunscreen. Natural shade from the cliffs provides occasional relief from the sun.
Located near the village of Akrotiri and close to Red Beach, it’s not accessible by car. Adventurous visitors can hike in from nearby Kambia Beach, though the easiest and most scenic option is to hop on a boat. Daily water taxis depart from Red Beach, while private or semi-private catamaran and yacht cruises provide a more luxurious experience, often including food, drinks, and hotel transfers for a stress-free beach day.
3. Agios Nikolaos – Cliffside Charm and Caldera Dives
Down a steep flight of 250 stairs carved into Oia’s rust-red cliffs lies the former fishing port of Ammoudi Bay, now bustling with catamarans ready for sunset cruises. Beyond the seafront tavernas, a short scramble across volcanic rocks leads to a dramatic outcrop where you can leap into the deep-blue waters of the caldera. Swim to the tiny floating chapel of Agios Nikolaos, a unique spot for an unforgettable dip.
On your return, refuel at Dimitris taverna, a local favourite since 1989, known for tomato fritters, fried calamari, and lobster linguine served right at the water’s edge. Among the best beaches in Santorini, this hidden gem is more about the adventure and atmosphere than sand. For a relaxing stay nearby, Canaves Oia Epitome offers stylish villas and suites with uninterrupted views and a restaurant where chef Tassos Stefatos puts a refined twist on Greek classics—a luxurious retreat amid iconic Santorini beaches.
4. Koloumbos
When locals talk about the best beaches in Santorini, Koloumbos often tops the list. Tucked along the island’s north-east coast, this black pebble beach remains refreshingly undeveloped and uncrowded. A towering cliff of layered lava offers natural shade at the southern end, but it’s still smart to bring an umbrella. Thanks to an active underwater volcano just five miles offshore, the sea here is slightly warmer—ideal for long, relaxing swims.
On clear days, the silhouettes of Ios, Amorgos, and Anafi line the horizon, adding to the remote, almost mystical vibe. Just a short drive inland, you’ll find two of the island’s finest wineries, Vassaltis Vineyards and Sigalas—perfect for ending your beach day with a glass of crisp Assyrtiko. Stay at the adults-only Aenaon Villas, perched on a low ridge with six cave-style suites, an infinity pool, and panoramic sea views—just a scenic stroll away from one of the best beaches in Santorini.
5. Katharos
As cruise crowds fill Oia’s postcard-perfect streets, those in the know slip away to Katharos beach—a tranquil hideaway just a 15-minute walk from the village centre. Tucked beneath wind-sculpted limestone cliffs, this black pebble stretch feels worlds apart, with sweeping views across the straits to Thirasia island. It’s an ideal spot for a quiet swim or a peaceful sunset, though it can get breezy when the meltemi wind blows.
At the cliff’s edge, Katharos Lounge offers plant-based dishes, sunset cocktails, and laid-back live music from local bands that spill into the night. The vibe is mellow, the views magnificent. For a stylish retreat nearby, Santo Pure Oia is a short walk away. This boutique sanctuary features spacious suites arranged around six domed clusters, each with its own pool—making it a serene and sophisticated base just minutes from the soulful calm of Katharos beach.
6. Mesa Pigadia
Tucked near the famed Red and White Beach, Mesa Pigadia—also called Black Beach—is one of the quieter Santorini beaches worth discovering. Reached via a gentle dirt road or by boat from Akrotiri beach, it’s a perfect post-ruins swim stop. The beach is lined with colourful fishermen’s shacks carved into limestone cliffs, adding charm to its rugged beauty. Sheltered from northern winds, the calm waters here are ideal for snorkelling, and a short swim through a sea cave even leads to White Beach. For peaceful caldera views, Astarte Suites offers 13 romantic rooms, each with a plunge pool or hot tub perched above the cliffs near Mesa Pigadia.
7. Monolithos
Among the best beaches in Santorini, Monolithos stands out with its long stretch of iron-grey sand framed by chalk-white cliffs sculpted by the wind. One towering rock, visible even from landing planes, lends the beach its name—Monolithos, meaning “one rock.” This breezy, spacious beach offers plenty of sunbeds and umbrellas, ideal for a relaxing day by the crystal-clear waters. Across the road, traditional tavernas serve up satisfying local fare, while further along the shore, Gaia Winery invites wine lovers to sample vintages inside a converted tomato factory. For luxury stays nearby, Nikki Beach Santorini blends beachside glam with indulgence—featuring 62 stylish rooms, a chic farm-to-table restaurant, and a vibrant Beach Club just steps from Monolithos beach.
8. Thirassia
Just a ten-minute boat ride from Ammoudi Bay, Thirassia offers a serene escape from Santorini’s crowds. Once part of the same island before the 1600 BC eruption, this untouched gem feels like Santorini decades ago. Rustic fishing houses dot dusty tracks, and pumice-strewn beaches welcome swimmers—and even the odd seal. The main village, Manolas, sits above the harbour, connected by 270 weathered steps, and mirrors the charm of Fira without the price tags. Local tavernas serve generous Greek salads, fried saganaki, and caper-laced dishes in a laid-back setting. Stay at Thirasia Paradise Suites, where three spacious rooms and a large pool offer front-row views of Oia glowing across the water—a perfect beachside retreat.
9. Red Beach
One of the most visually arresting Santorini beaches, Red Beach sits just a short walk from the ancient ruins of Akrotiri, famously buried by a volcanic eruption in 1628 BC. Named for the towering ochre-red cliffs that rise above its pebble-strewn shore, the beach feels almost otherworldly. Accessible only via a dirt path from Akrotiri or by boat, it stays relatively calm by day—until golden hour, when sunset-seekers and Instagrammers arrive to capture the fiery hues. Facilities are minimal, so pack water, sunscreen, and snacks.
For a luxurious stay nearby, Phōs Hotel offers elegant villas and suites with private plunge pools and sweeping caldera views—bringing Oia-level indulgence to this wild corner of Santorini beaches.
10. Exo Gialos
Just a 10-minute drive from Fira, Exo Gialos is one of the best beaches in Santorini for those seeking peace away from the crowds. Curving along the island’s east coast, this black-pebble beach is backed by camel-coloured cliffs pocked with old boat caves. Locals call it ‘Fira beach’ and come here to watch the sun rise in blazing colour over the Aegean. It’s a refreshing spot to unwind after a day of sightseeing.
As the heat fades, head to Yalos Beach Bar for seafood grilled to perfection, craft cocktails, and sunset DJ sets. For an indulgent stay nearby, Grace Hotel offers sleek rooms and suites with plunge pools and sunset views, plus gourmet dining at Varoulko by Michelin-starred chef Leftheris Lazarou— a stylish finale to a perfect day exploring Santorini beaches.
