One island, 99 beaches (and more)

Kythnos boasts more than 99 beaches – many of which remain unexplored by the tourist eye. Here, you won’t just find beach bars and sunbeds in a row. You will also find shade from the tamarisk trees, clear waters, and a calmness to leave the stress of the city behind you.

North Kythnos

Agios Sostis

Few people know about Agios Sostis beach, one of the northernmost on the island. It takes its name from the small church perched on the edge of the rock, completing a picturesque scene that looks as though it’s been painted. This serene, windless beach features crystal-clear waters and is primarily made up of sand and pebbles.

Potamia

Potamia Beach is located in the northeastern part of the island, just before Agios Sostis Beach. Upon arrival, you’ll be greeted by a breathtaking sandy beach with emerald waters, plenty of space, and… almost no crowds. It’s an ideal spot for families or couples who appreciate solitude.

Schinari

Schinari is one of the quietest and most beautiful beaches on the northeastern side of Kythnos. Located in front of the small settlement of the same name, near the popular Loutra, it features rocky formations at its edges, turquoise waters, and natural shade from tamarisk trees. This beach offers a sense of absolute tranquility. It is ideal for those looking to escape the tourist crowds and enjoy an authentic swim, with their gaze fixed on the endless blue and the sun dancing on the sea.

Agia Irini

In a bay sheltered from the winds, just 1.5 kilometers from Loutra, Agia Irini Beach stretches out serenely, as if inviting you to leave all your worries behind. Small and consisting of sand and pebbles, it offers easy access and calm waters, making it ideal for families or anyone seeking a peaceful morning swim. The chapel of Agia Irini stands quietly above the beach, adding a spiritual touch to the landscape. It is one of those places that will captivate you with its simplicity – an authentic piece of Kythnos, perfect for a moment of calm.

East Kythnos

Agios Ioannis Theologos

The beach of Agios Ioannis Theologos is one of those spots that will make you feel like you discovered it first. Tucked away in a small, quiet bay, with the simple chapel of the saint in the background, it’s perfect for those who love the simple, authentic Cycladic summer. This peaceful, spacious beach features pebbles, sand, and clear waters. You won’t find a beach bar or sun loungers—and that’s the whole point. Here, you’ll only hear the sound of the waves, and if you stay a little longer, you’ll be rewarded with a sunset that looks like it came straight out of a postcard.

Agios Stefanos

This beach is located on the eastern part of the island and, due to its position, is sheltered from the north winds and the meltemi. It’s a small bay with calm, shallow waters in shades of turquoise, offering a peaceful escape. The white chapel of Agios Stefanos in the background blends seamlessly with the landscape, resembling a painting. If you visit in the afternoon, you’ll feel as though you’re in a Cycladic dream. Perfect for relaxation, calm swims, and those who love summer, this spot also offers taverns serving fresh seafood and local dishes.

Antonides

Antonides is one of the most discreet yet charming beaches of Kythnos. Located in eastern Kythnos, behind some dirt roads and low rocks, this small natural haven reveals itself, with crystal-clear waters and complete silence. Οnly the cicadas and the waves accompany you. It has no trace of tourism, no beach bars or sun loungers, so it’s best to go prepared. However, it has exactly what makes it special: the tranquility you didn’t know you needed.

South Kythnos

Skylou Beach

Unless a local tells you, you’ll have a hard time finding it. Skylos is a small, secluded beach in southeastern Kythnos, tucked away among hills and seemingly accessible only to the luckiest of souls. Wild, unpretentious, and almost always empty, it offers an authentic landscape with clear waters, small pebbles, and a serenity that’s hard to find elsewhere. There are no shaded areas or facilities—but it’s the perfect place to feel free, dive without a second thought, and enjoy Kythnos in its purest form.

Gaidouromantra

Don’t let the name fool you—Gaidouromantra is one of the most impressive, almost cinematic beaches of Kythnos. Located in the southern part of the island, access isn’t the easiest, but it’s worth every minute of the journey. Wild beauty, dark rocks surrounding it, incredibly clear waters, and a sense of freedom that makes you want to stay for hours. It has no facilities, but it offers something hard to find elsewhere: the feeling of being alone in a small earthly paradise. Ideal for those who love adventure and solitude.

Alyki

It is located in the southwestern part of Kythnos and offers an almost minimalist setting: a mix of sand and pebbles, calm waters, and absolute tranquility. It’s neither crowded nor striking at first glance—but the longer you stay, the more it captures your heart. Perfect for peaceful swims, reading under the sun, and romantic afternoons with views of the Aegean.

West Kythnos

Kastellas

Hidden in western Kythnos, this beach boasts turquoise waters, a long stretch of sand, and clear, shallow seas along with a rare sense that time has slowed down with you. Ideal for those who love wide, open shores, it unfolds with fine, light-colored sand and sparse surrounding vegetation that lends it an earthy, understated beauty.

The surrounding landscape is bare and unmistakably Cycladic—gentle hills, dry stone walls, and a few scattered thyme bushes, fragrant under the sun’s warmth. And the best part? As the sun begins to set, the colors of the beach transform: the water glows golden, and the scenery takes on that magical melancholy only an authentic Cycladic afternoon can offer.
