TRAVEL GUIDES & INSPIRATION
Practical tips, island guides and local stories to help you plan your perfect day at sea from Athens.
Athens gives you about three days of temples and museums before it starts asking for something back. Here is how to actually spend a day on the water.
Ask ten people for the best day trip from Athens and you will get ten answers, most of them ruins. For a first trip, the right answer is simpler.
You have seen the Acropolis, or you have it booked for tomorrow. Here is what to do with the two or three days sitting on either side of it.
Almost every Athens itinerary makes the same mistake. It packs the city so tightly that the sea, twenty minutes away, never makes the list.
Packing for a day cruise sits somewhere between a beach day and a flight. Here is what to bring, and more usefully, what to leave in the hotel.
Almost everyone booking their first day cruise worries about the same handful of things, and almost none of them turn out to matter. Here is what actually happens.
Same route, same destinations, different experience. Here’s an honest breakdown of what each package includes and who each one really suits.
Agistri is the Saronic island that never got around to overdeveloping itself. Here is what you actually see, do and eat in two hours at the port.
You can’t reach it by ferry and you won’t find it on most maps — but this uninhabited islet offers some of the clearest water in the Saronic.
If Agistri is the quiet stop, Aegina is the one with something to say. Neoclassical facades, a working waterfront, and pistachios sold on every second corner.

Whether you’re planning your first trip to Greece, adding a day at sea to a longer Athens itinerary, or simply looking for a break from the summer crowds, Athens Swimming Cruise helps you experience the Saronic Gulf the way it’s meant to be enjoyed — slowly, generously and with plenty of time to swim.
The Saronic Gulf offers the most accessible island destinations from Athens. Agistri welcomes visitors with golden beaches, crystal-clear waters and a charming port lined with local shops and cafés. Aegina brings neoclassical streets, a lively main port and its famous pistachios — with a walking tour through the town that once served as Greece’s first capital. Between them lies Metopi, an uninhabited islet reachable only by boat, where you swim in some of the clearest turquoise water in the region. All three sit within easy sailing distance of Private Marina Delta Kallithea.
It depends on what you’re after. Agistri is smaller and more relaxed — perfect for swimming at golden beaches, exploring coastal shops and cafés, or simply soaking up the atmosphere of a peaceful Greek island. Aegina is larger and more historic, with neoclassical streets from its time as Greece’s first capital and the world-famous pistachios grown across the island. Most travelers don’t have to choose — our day cruise stops at both main ports, along with a private swim stop at Metopi in between.
Ferries are a great choice if you’re staying overnight on one island. For a single day, though, Athens Swimming Cruise is the better option — you visit three destinations in one trip, avoid juggling ferry timetables, and get extras like a Mediterranean lunch cooked fresh on board, a free 1-hour guided walking tour in Aegina, and a private swim stop at Metopi. Ferries don’t stop at Metopi at all — the uninhabited islet is only reachable by boat.
The main season runs from May through October. June and September offer the best balance of warm weather, calm seas and fewer crowds. July and August are the busiest and hottest months but also the most vibrant on the islands. Water temperatures stay swimmable well into October, making early autumn a favorite for repeat visitors.
Absolutely. Swimming is one of the highlights but never a requirement. The vessel has plenty of deck space to relax, shaded lounges to enjoy the views, and safe entry points for those who prefer a gentle dip near the boat. Life vests are always available on board, and swim stops happen in calm, sheltered waters rather than open sea.
