The closest islands to Athens are the Saronic Gulf islands — Aegina, Hydra, Poros, Agistri and Spetses — all reachable by ferry from Piraeus in well under two hours. Plan the boats and island days alongside skip-the-line sightseeing tickets and tours from My Greece Tours.
Island escapes are one of the great pleasures of the Athens travel guide. The sections below cover the closest islands, how to reach them, which Saronic island suits you, the popular one-day cruise, and the Cycladic islands within day-trip range.
What are the closest islands to Athens?
The closest islands to Athens are the five Saronic Gulf islands: Aegina, Agistri, Poros, Hydra and Spetses. They lie in the gulf between Attica and the Peloponnese, and all are reachable by ferry from the port of Piraeus in roughly 40 minutes to two hours. Aegina is the nearest at under an hour by fast boat, while Hydra and Spetses sit further south. Their proximity makes them ideal for day trips and short stays from the capital.
When Athenians want sea and a change of pace, they look to the Saronic Gulf, the stretch of water that separates the Attica peninsula from the Peloponnese. Five inhabited islands sit within easy reach here, and together they form the most convenient island group for anyone based in the capital.
Aegina is the largest and closest, famous for its pistachios and its hilltop Temple of Aphaia. Tiny Agistri lies just beyond it, pine-covered and quiet. Poros is separated from the Peloponnese by a narrow channel only a few hundred metres wide. Hydra, car-free and elegant, is lined with stone captains’ mansions from the eighteenth century. Spetses, the southernmost, is wooded and refined. None of them requires an overnight stay, though each rewards one.
How do you get to the islands from Athens?
You reach the Saronic islands by ferry from the port of Piraeus, the main harbour serving Athens. Take Metro Line 1 (green) directly to Piraeus station, a journey of around 20 to 30 minutes from the centre, then walk to the gate for the Saronic boats. High-speed catamarans and conventional ferries run frequently through the day, with fast boats reaching Aegina in about 40 minutes and Hydra in around 90 minutes. Buy tickets online in advance in summer.
Getting to the Saronic islands is refreshingly simple. The gateway is Piraeus, the great port just southwest of the city, and the easiest way to get there is Metro Line 1, the green line, which runs from central stations such as Monastiraki and Omonia straight to the Piraeus terminus in twenty to thirty minutes.
From the metro station the Saronic departures leave from the gates around the eastern side of the harbour, a short signed walk away. Two kinds of boat serve the islands: fast hydrofoils and catamarans that prioritise speed, and slower conventional car ferries that cost less and carry vehicles. Fast boats reach Aegina in roughly forty minutes, Poros in about an hour, Hydra in around ninety minutes and Spetses a little beyond. Departures are frequent in summer, but seats sell out, so book online ahead and arrive at the gate fifteen minutes before sailing.
Which Saronic island should you choose?
Choose Aegina for the easiest trip, a working town, pistachios and the Temple of Aphaia; choose Hydra for car-free elegance, stone mansions and a chic harbour; choose Poros for a green, gentle island close to the Peloponnese; and choose Spetses or Agistri for quieter, wooded escapes. Aegina suits families and first-timers, Hydra suits romance and walking, and the others reward those wanting calm. Each has a distinct character despite the short distances between them.
The five islands are close together yet markedly different, so the right choice depends on what you want from the day. Aegina is the all-rounder and the simplest target: a lively port town, good tavernas, the celebrated pistachio groves, and the well-preserved Doric Temple of Aphaia on a pine-clad hill, all within a short bus ride.
Hydra is the showpiece, a car-free island where donkeys and water taxis replace traffic, and grand grey-stone houses built by wealthy sea captains climb the slopes around a horseshoe harbour. Poros is the greenest and gentlest, divided from the mainland by a channel you can almost swim, with a clock-tower hill and easy swimming. Spetses, ringed by pine forest and old mansions, has a genteel, yachting air, while little Agistri offers clear coves and a slow pace. For a first visit, Aegina or Hydra rarely disappoints.
What about a one-day island cruise?
The classic option is the one-day Saronic cruise that visits three islands — usually Hydra, Poros and Aegina — in a single day from Athens. These cruises depart from the coast near Piraeus or Flisvos, run roughly 9 to 12 hours, and include time ashore on each island, on-board meals and often live music and dancing. They suit travellers who want a taste of several islands without arranging separate ferries, though time on each island is limited to a couple of hours.
If you cannot decide between the islands, the popular one-day cruise solves the problem by visiting three of them in a single outing. The standard itinerary calls at Hydra, Poros and Aegina, giving a generous sampler of the Saronic Gulf in one relaxed day at sea.
These cruises typically leave from the coastal embarkation points near Piraeus or the southern suburbs in the morning and return in the early evening, a full day of around nine to twelve hours. Lunch is usually served on board, often with live music and Greek dancing as the boat crosses between islands, and you get a couple of hours ashore at each stop to wander the harbour, swim or climb to a viewpoint. The trade-off is time: a few hours per island is enough for a stroll and a coffee, not for exploring in depth. For that, a dedicated ferry to one island serves better. As a scenic, sociable overview, though, the three-island cruise is hard to beat.
Timing shapes a Saronic day trip. The islands are busiest and warmest from June to September, when the ferries run most often and the sea is ideal for swimming, while spring and autumn bring milder weather, thinner crowds and lower prices, making May, June, September and October arguably the loveliest months to go. Even in winter the closest islands stay accessible by daily boats, though some tavernas and shops close out of season, so off-peak visitors should check ahead before setting out.
Many travellers combine two nearby islands in one outing, since inter-island boats link them in twenty to forty minutes. A popular pairing is Hydra and Poros, which sit close together on the same ferry line, or Aegina with tiny Agistri just across the water. Whatever you choose, build in time for the essentials of an island day: a swim in clear water, a long lunch of fresh fish at a harbour taverna, a walk to a viewpoint, monastery or temple, and an unhurried coffee by the boats before the ferry back to Piraeus.
Packing for a Saronic day trip is simple: swimwear, a towel, sun protection, comfortable shoes for cobbled lanes and steps, and some cash for the smaller tavernas and shops that may not take cards. The islands are well organised for visitors, with maps at the ports, local buses or water taxis on the larger ones, and English widely spoken, so independent travel is straightforward, safe and rewarding for first-timers and returning visitors alike.
Which Cycladic islands are within reach?
Beyond the Saronic Gulf, the nearest Cycladic islands — Kea, Kythnos and Andros — are reachable in roughly one to two hours by ferry, mostly from the smaller Attica ports of Lavrio and Rafina rather than Piraeus. Kea (Tzia) is the closest, about an hour from Lavrio, and is popular with Athenian weekenders. These islands are quieter and less touristy than Mykonos or Santorini, making them feasible for an ambitious day trip or, better, a short overnight stay.
The Saronic islands are the obvious day trips, but a few Cycladic islands also lie within reach if you are willing to use the smaller Attica ports. The two alternative harbours are Rafina, east of Athens near the airport, and Lavrio, at the southern tip of Attica, both connected to the city by bus.
Kea, known to Greeks as Tzia, is the nearest Cycladic island, only about an hour from Lavrio, and it fills with Athenian weekenders because of that proximity. Kythnos, with its thermal springs and quiet coves, sits a little further on the same route, while Andros, a large green island with good walking trails, is reached from Rafina in around two hours. These islands are calmer and more authentic than the famous Cyclades, and although a same-day return is possible to Kea, an overnight stay turns any of them into a proper escape. The questions below cover what travellers ask most.
For travellers with more time, the Saronic islands also reward an overnight stay. Spending a night on Hydra or Spetses lets you experience the islands after the day boats leave, when the harbours quieten and the tavernas fill with locals, and it opens up quieter beaches and longer walks beyond the main town. Even one night turns a rushed day trip into a relaxed mini-break, and ferries are frequent enough to make a two-island, two-night loop from Athens entirely practical in the warmer months, when the long evenings are perfect for a harbour-side dinner under the stars before you sail back to the capital.
Frequently Asked Questions
Which is the closest island to Athens?
The closest island to Athens is Aegina, in the Saronic Gulf. Fast catamarans reach it from the port of Piraeus in about 40 minutes, and conventional ferries in around an hour. Tiny Agistri lies just beyond Aegina and takes a little longer. Aegina’s proximity, frequent boats and easy harbour town make it the simplest island day trip from the capital.
Can you do an island day trip from Athens?
Yes, a day trip to the islands from Athens is very doable. The Saronic islands — Aegina, Poros and Hydra especially — are close enough for an independent return by ferry from Piraeus in a single day. Alternatively, organised one-day cruises visit three islands with lunch and time ashore on each. Reach Piraeus on Metro Line 1, and book fast-boat tickets ahead in summer.
Do you need a car on the Saronic islands?
No, you do not need a car on the Saronic islands, and on Hydra cars are banned entirely, with donkeys and water taxis used instead. Aegina, Poros and Spetses have buses, taxis and rental scooters or bikes for getting around, but their main towns and harbours are walkable. For a day trip you can comfortably explore on foot and by local transport without bringing a vehicle on the ferry.
