Exo Gialos Beach: Santorini’s Quiet Volcanic Shore Below Karterados
Santorini’s famous beaches come with a price. Perissa and Kamari deliver the black sand and the facilities, but in August they also deliver crowds, queues for sunbeds and a fight for parking. Exo Gialos beach offers the quieter alternative, and it sits closer to Fira than any of them.
Quick answer: Exo Gialos beach is a small volcanic shore on Santorini’s east coast, directly below the village of Karterados and about ten minutes from Fira. The sand is dark grey and pebbly, the water is clear and deep, and there are only a handful of tavernas. It has almost no organised facilities, which is exactly why locals use it. Come here for a quiet swim close to town, not for beach clubs or sunbed service.
Where Exo Gialos Is
Exo Gialos, sometimes written Exo Yialos, lies on the island’s east coast, below Karterados. It is often called Karterados beach for that reason.
Fira is a short drive inland and uphill. That proximity is the whole point: you can be swimming fifteen minutes after leaving the caldera path.
- By car: a few minutes down from Karterados, with free roadside parking near the shore
- On foot from Karterados: roughly 20 to 25 minutes downhill, and a steeper walk back up
- From Fira: about 10 minutes by car
There is no direct bus, so a car, scooter or taxi is the practical choice.

What the Beach Is Actually Like
Set your expectations correctly and Exo Gialos is a pleasure. Arrive expecting Perivolos and you will be disappointed.
The shore is dark volcanic sand mixed with grey pebbles, eroded from the lava and basalt catalogued in the Smithsonian Global Volcanism Program record for Santorini. Underfoot it is coarser than Perissa, so water shoes help, both for comfort and for the entry into the sea.
The water deepens quickly. That makes it better for confident swimmers than for toddlers paddling.
What you will find:
- A long, narrow strip of dark sand and stone
- Clear, deep water with good visibility
- A few tavernas set back from the shore
- Limited sunbeds, mostly tied to the tavernas
- Little shade, so bring an umbrella
What you will not find:
- Beach clubs, music or organised watersports
- Lifeguards
- Changing rooms or showers in most sections
Why Locals Choose It
Ask someone who lives in Fira where they swim after work, and Exo Gialos comes up often. Three reasons explain it.
It is close. Most of Santorini’s good beaches are a 20 to 30 minute drive from the caldera villages. This one is not.
It is calm in the right conditions. The east coast is sheltered from some of the summer meltemi wind that hits the south.
It stays quiet. With no beach club economy, the crowd stays small even in August.
The trade-off is honest: fewer facilities, less sand, no scene. For a swim rather than a day out, that trade is usually worth making.

Where to Eat
The tavernas along Exo Gialos are small, family run and focused on fish. They are not tourist restaurants with laminated menus in six languages.
Expect fresh catch, simple salads and Santorini staples like fava and tomatokeftedes, the island’s tomato fritters.
A practical tip: lunch here runs late by northern European standards. Arriving at 12pm often means an empty room; 2pm is the local hour.
The Best Time to Visit
Early morning is the finest time on this beach. The water is flat, the light is low across the dark sand, and you will often have long stretches to yourself.
Late afternoon works well too, once the day trippers have gone back to the caldera for sunset.
- June and September: warm sea, quiet shore, ideal conditions
- July and August: still far quieter than Perissa, though the sand gets hot
- May and October: peaceful, cooler water, most tavernas still open
- Winter: dramatic and empty, though swimming is for the brave
Note that the east coast catches morning sun and loses light earlier in the evening than the west. For sunset, the caldera side remains unbeatable.
What to Bring
- Water shoes. The pebbles and the hot dark sand both argue for them.
- An umbrella or shade. Natural shade is scarce.
- Water and snacks. There is no supermarket at the shore.
- A towel you do not mind on stones. A thicker mat beats a thin towel here.
- Cash. Small tavernas do not always take cards.
Other Beaches Within Easy Reach
- Monolithos: about 10 minutes, shallow and calm, the family choice
- Kamari: about 10 minutes, paved promenade and full facilities
- Vlychada: about 15 minutes, sculpted white cliffs and dark sand
- Perissa and Perivolos: about 15 to 20 minutes, the long social strip

The Short Version
Exo Gialos will not win a photo contest against Vlychada, and it will not out-entertain Perivolos. That is not its job.
It is the beach you use when you want to swim rather than plan an outing. Dark volcanic sand, clear deep water, a taverna lunch, and no queue for any of it.
For anyone staying in Karterados or Fira, it is the most practical swim on the island. Bring water shoes, go early, and let the crowds have Perissa.
