There is a strange thing that happens when people visit Athens. They see the Acropolis, they eat souvlaki in Monastiraki, they wander around Plaka, and then they either fly to Santorini or Mykonos, completely ignoring the fact that there are gorgeous islands less than an hour from the city.
The Saronic Gulf islands sit right off the coast of Athens. You can literally see some of them from the shore. They have pine forests, turquoise water, ancient temples, and pistachios so good they have their own protected status. And yet most international tourists have absolutely no idea they exist.
This is either a tragedy or a gift, depending on how you feel about sharing a beach.
Aegina: The Pistachio Island With a Surprise Temple
Aegina is about an hour from Piraeus by regular ferry, or 40 minutes by the fast one. It is close enough that Athenians go there for lunch on weekends, which should tell you something about how easy the trip is.
The first thing you will notice about Aegina is the pistachios. They are everywhere. Shops on the waterfront sell them roasted, salted, candied, turned into ice cream, baked into pastries, and blended into spreads. Aegina pistachios have been cultivated on the island since the late 1800s and they have a protected designation of origin, which is the food equivalent of a really fancy diploma. They taste noticeably different from the pistachios you buy at the supermarket. Better. Much better.
But the real surprise is in the northeast corner of the island. The Temple of Aphaia, built around 500 BC, sits on a hilltop surrounded by pine trees with views across the sea to both Athens and the Peloponnese. It is one of the best-preserved ancient temples in Greece, and on a clear day, you can see the Acropolis from it. This creates what is sometimes called the Sacred Triangle: three ancient sites (the Acropolis, the Temple of Poseidon at Cape Sounio, and the Temple of Aphaia on Aegina) forming a near-perfect triangle across the water.
The town of Aegina is charming in the way that places are charming when they are not trying to be. Fishing boats line the harbor, old men argue about politics in the cafes, and the fish restaurants serve whatever was caught that morning. There is a quietness to it that feels increasingly rare in the Aegean.
Agistri: The Tiny Green One Nobody Talks About
Agistri is either 90 minutes from Piraeus by slow ferry or about 15 minutes from Aegina by local boat. It is a very small island. You can walk across it in about 40 minutes. And roughly 80% of it is covered in pine and olive trees, which gives the whole place a smell that is half forest, half sea.
The main settlement, Skala, has a small beach right in front of it that manages to be both convenient and beautiful, which is a combination that usually only exists in travel brochures. The water is the kind of clear where you can see fish swimming around your feet while you are standing in it, and the pine trees come right down to the shore, providing actual natural shade. No umbrellas needed. The trees have you covered. Literally.
Walk south from Skala and you will reach Aponisos, a small bay with water so clear it barely looks real. The further you go around the island, the quieter it gets. Dragonera, on the southwest side, is a rocky beach with excellent snorkeling and approximately zero crowds, even in August.
What makes Agistri special is its scale. Because it is so small, you can explore the entire island in a day and still have time to spend three hours doing nothing on a beach. There are no major historical sites, no museums you feel obligated to visit, and no nightlife to speak of. It is just trees, sea, and the kind of quiet that makes you wonder why you live in a city.
Moni: The Uninhabited One With the Best Water
Just off the southwest coast of Aegina, near the village of Perdika, sits Moni, a small uninhabited islet that you can only reach by boat. There is no port, no village, no infrastructure beyond a small beach with some natural shade. What there is, however, is some of the most absurdly clear water in the entire Saronic Gulf.
Moni is the kind of place that makes you question whether you have been swimming in the wrong places your whole life. The water is turquoise, transparent, and calm, protected by the surrounding islands from the open sea. The snorkeling is excellent. Fish, sea urchins, and the occasional octopus going about its business as if you are not even there.
Small boats from Perdika on Aegina make the crossing to Moni regularly in summer, or you can arrive by your own private sailing trip from Athens. Approaching by boat is actually the ideal way to experience Moni, because you can anchor in the bay, swim directly off the boat, and have the kind of afternoon that looks like it belongs in someone else’s Instagram but is actually happening to you.
The island has some walking paths through the scrubby vegetation, and there are free-roaming peacocks, deer, and kri-kri goats living there, introduced decades ago and now very much at home. Even without the wildlife, Moni is worth the trip purely for the water.
How the Saronic Gulf Compares to the Cyclades
Here is the honest comparison. The Cyclades (Mykonos, Santorini, Paros, Naxos) have the iconic whitewashed architecture, the dramatic volcanic landscapes, and the Instagram moments. The Saronic Gulf islands have none of that, and they are better for it in certain ways.
The Saronic islands are green. Covered in pines, olive trees, and wildflowers. They smell like a forest next to the sea. The Cyclades are beautiful but often dry and rocky. If your idea of a perfect island involves shade, green hills, and the sound of cicadas, the Saronic Gulf is your place.
The proximity to Athens is the biggest advantage. No flights, no five-hour ferry rides, no airport transfers. You can be swimming off Aegina before tourists on Santorini have finished their airport coffee. And because these islands attract mostly Greeks and very few international tourists, the prices are lower, the restaurants are more authentic, and the beaches are less crowded.
The flip side is that the Saronic islands do not have the Cycladic villages, the blue-domed churches, or the sunset views over volcanic calderas. They are a different kind of beautiful. More subtle, more lived-in, more like discovering a secret than arriving at a destination.
The Best Way to See Them
You can absolutely take the ferry from Piraeus and island-hop the Saronic Gulf on public transport. The connections are good, the ferries are frequent, and it is all very affordable.
But here is the thing. The Saronic Gulf was essentially designed for sailing. The islands are close together, the waters are protected, and the coastlines are full of small coves and beaches that you cannot reach by road. Arriving by boat means you get to see the islands the way they were meant to be seen: from the water, with the freedom to stop wherever looks good.
A day trip from Athens that combines Aegina, Moni, and Agistri is one of the best things you can do with a day in the Greek summer. You swim in three completely different settings, eat fresh fish on a harbor, taste the best pistachios of your life, and get back to Athens in time for dinner.
Why Nobody Talks About This
The Saronic Gulf islands do not have marketing budgets. They do not appear in travel magazines next to photos of sunset cocktails. They do not have influencer partnerships or viral TikTok moments. They are just quiet, beautiful islands sitting in plain sight, an hour from one of Europe’s most visited cities.
Part of the reason international tourists skip them is simple geography. Everyone assumes you need to take a long ferry or a flight to reach “real” Greek islands, so they look right past the ones that are closest. The irony is that the Saronic islands often have better swimming water, fewer crowds, and more authentic Greek island life than the famous ones.
The secret is not really a secret. Greeks know about these islands. They have been going to them for weekends and holidays for generations. It is mostly foreign visitors who have not caught on yet.
And honestly, that might be the best part.
