The Closest Islands by Ferry
The Saronic Gulf islands, just south of Athens, are the quickest escape from the city, with frequent departures from Piraeus throughout the day. By fast ferry, the rough journey times are: Aegina in about 40 minutes, Poros in around an hour, Hydra in about an hour and a half, and Spetses in roughly two hours. Conventional ferries take roughly double, but are more comfortable and, where available, carry cars. Several operators run these routes, with services most frequent in summer, and Aegina in particular can see departures as often as every half hour or so in peak season. That reliability is a big part of why the Saronic islands appeal to people who want an island they can reach easily and often.
Aegina, the Easiest Of All
Aegina is the clear winner for accessibility. The short hop from Piraeus makes it almost a suburb of Athens, yet it keeps a genuine island character, with traditional architecture, good beaches, and the famous Temple of Aphaia. Its closeness brings practical benefits too. The port town has shops, restaurants, and services on the doorstep, and utility and internet connections tend to be better than on remote islands. That mix of convenience and real island life draws weekend owners and year-round residents alike, which supports a steadier market than purely seasonal spots.
Reaching the Bigger Islands by Air
For islands further out, flying is often the easier route. Athens airport has year-round flights to Crete, with several services a day to Heraklion and Chania, plus seasonal flights to popular spots like Mykonos, Santorini, Rhodes, and Corfu. Flights typically take somewhere between 45 minutes and an hour and a half, which puts even distant islands within reach for a short visit. It's worth remembering that many of these routes are seasonal, busiest and most frequent in summer and thinner in winter, which matters if you'll use or let the property out of season. For somewhere like Crete, where the ferry from Athens is an all-day or overnight trip, flying makes a real difference.
Why Access Is Worth Weighing
How easily you can reach a property affects more than convenience. Good links widen the appeal, both for you and, if you let it, for guests, which tends to mean steadier use across the year. They also help when you come to resell, since buyers value easy access. And on a personal level, an easy journey means you're far more likely to use the place often, which is rather the point of owning it. One honest aside: if the very easiest access from Athens is the goal, it's worth remembering the mainland too. The nearer parts of the Peloponnese are reached by road in a couple of hours, with no ferry or flight to plan around at all.
