Athens sits at the edge of one of the most island-studded seas in the world, and the proximity of genuinely beautiful, genuinely Greek islands to the capital is one of the city’s best-kept secrets from international visitors. Within 35 minutes to 2 hours from Piraeus port, you can be on Aegina with its remarkable ancient temple and famous pistachio groves, on car-free Hydra where donkeys are the only transport and the harbor looks unchanged since the 18th century, on Poros with its pine forests and Venetian clock tower, or on the tiny island of Spetses with its horse-drawn carriages and revolutionary history. These are not tourist-built destinations — they are real Greek islands where Athenians have been escaping on weekends for generations, and they offer the authentic island experience that the famous Cyclades increasingly struggle to provide at a fraction of the cost and complexity.
This guide covers every island accessible as a day trip or overnight stay from Athens, honestly and completely — what each one actually offers, how long the crossing takes, what it costs, and who each island suits best. For the broader picture of Greek island travel including the Cyclades, see our best Greek islands guide. For ferry booking across all routes, our complete Greek ferry guide covers everything.
Aegina: Ancient Temple, Famous Pistachios, 35 Minutes Away
Aegina is the most visited island day trip from Athens and earns its popularity honestly. It combines one of the finest ancient Greek temples in existence with excellent beaches, the famous Aegina pistachios (PDO-protected, considered the finest in Greece), a pleasant harbor town, and a ferry crossing that takes just 35 minutes on the high-speed Flying Dolphin or about an hour on the conventional ferry. For a day trip that gives you genuine ancient history, good swimming, excellent food, and the feeling of an authentic Greek island rather than a tourist performance, Aegina consistently delivers.
The Temple of Aphaia is the island’s archaeological centerpiece — a remarkably well-preserved Doric temple from approximately 500 BC, perched on a pine-forested hill in the northeastern part of the island with extraordinary views over the Saronic Gulf toward Athens and the Peloponnese. The temple is contemporary with the Parthenon and shows the late Archaic/early Classical Doric order at its finest — the proportions are near-perfect, the sculptural pediments (now in Munich) were among the finest of the period. Entry is €6. The combination of excellent ancient temple, beautiful pine forest, and hilltop sea views makes this one of the most rewarding ancient sites accessible from Athens.
The pistachio groves covering the island’s interior produce the nuts that every Greek knows as “Aegina pistachios” — sweeter and more aromatic than Turkish or Californian equivalents, protected by PDO status. The harbor shops in Aegina Town sell pistachios in every form: raw, roasted, salted, in paste, in sweets. Buying a bag of fresh-roasted Aegina pistachios from a harbor vendor and eating them on the ferry home is one of the genuine pleasures of the trip.
Ferry from Piraeus: Flying Dolphin (35 min, €9-12 one way) or conventional ferry (1 hour, €8-9). Book through Ferryscanner — multiple daily sailings from early morning to late evening. For a day trip that includes the Temple of Aphaia with guided interpretation, GetYourGuide offers organized tours from Athens that handle the logistics. Book Athens accommodation for your Aegina base through Booking.com.
Hydra: The Most Beautiful Island Near Athens
Hydra is the island that consistently surprises visitors expecting a typical Greek island beach destination and finding instead one of the most atmospheric and architecturally distinguished places in Greece. There are no cars on Hydra — no motorcycles, no bicycles. The only motorized transport is the supply boats that bring necessities to the harbor. Everything else moves by donkey, on foot, or by water taxi. The result is an island that sounds and smells different from any other — the clip of hooves on stone paths, the absence of engine noise, the harbor reflecting the 18th-century stone mansions of the shipping families who built them.
Hydra Town is built around a horseshoe harbor lined with two-story stone captain’s houses (archontika) constructed by the ship captains who made Hydra wealthy in the 18th and early 19th centuries. The island played a significant role in the Greek War of Independence — its merchant fleet provided crucial naval capacity to the revolutionary cause. The cannon on the harbor promontory are not decorative. The architecture of the houses, with their Italianate influences and careful stone construction, is genuinely beautiful — more refined and more historically layered than the Cycladic whitewash of the more famous islands.
Hydra’s beaches are rocky rather than sandy — you swim from the rocks, from the small concrete platforms at the edges of coves, or from boats. The water is clear and the swimming is excellent. The best swimming spots are accessible on foot along the coastal path east of the harbor (15-30 minutes’ walk) or by water taxi to more remote coves. The island rewards walking — the interior paths to the monasteries above the town, the coastal path to Kamini and Vlyhos, the climb to the windmills above the harbor — all offer perspectives on the island that most day trippers who stick to the harbor never see.
Ferry from Piraeus: Flying Dolphin (1 hour 40 minutes, €25-30 one way) or conventional ferry (2.5 hours, €15-20). Book through Ferryscanner. Hydra is best as an overnight stay rather than a day trip — the island in the evening after the day boats leave, when the harbor belongs to the residents and the long-stay visitors, is a completely different and more beautiful experience. Book accommodation in Hydra through Booking.com — the historic mansions converted to small hotels are among the most atmospheric accommodation options in Greece. For organized Hydra day trips from Athens with a guide, GetYourGuide offers several options including sailing tours that combine Hydra with Poros and Aegina.
Poros: Pine Forests and a Pretty Harbor Town
Poros sits separated from the Peloponnese mainland by a narrow channel just 200 meters wide — the passage between island and mainland is so narrow that the ferry seems to thread between buildings. The island consists of two parts: the small volcanic cone of Sferia, covered entirely by Poros Town, and the larger pine-forested Kalavria connected to it by a narrow isthmus. The town itself, climbing the hillside above the harbor with its pastel houses and the famous clock tower, is genuinely pretty without being spectacular — Poros is the most modest of the Saronic islands but consistently pleasant.
The island’s great asset is the pine forest of Kalavria, which covers most of the larger part of the island and provides shade, walking trails, and a cool fragrance that the more exposed Aegean islands lack. The forest roads and paths are excellent for cycling or walking. Scattered through the forest are the remains of the ancient Sanctuary of Poseidon — modest ruins, not worth a special trip, but atmospheric in the forest setting. The beaches on Kalavria’s northern coast (Askeli, Kanali, Neorio) are sandy and calm — better for family swimming than the rocky Hydra alternatives. Ferry from Piraeus: 2 hours, €15-20 one way through Ferryscanner.
Spetses: The Most Stylish of the Saronic Islands
Spetses is the furthest of the Saronic islands from Athens (2.5 hours by Flying Dolphin from Piraeus) and rewards the extra journey time with the most sophisticated and beautiful of the Saronic island towns. Like Hydra, Spetses has restricted motor vehicles — only residents can use cars on the island, and visitors move by horse-drawn carriage, bicycle, or water taxi. The result is a similar peacefulness to Hydra but with a slightly different architectural character: the old town (Dapia and the old harbor area) has Venetian-influenced two-story mansions, a small archaeological museum in a fine old house, and a harbor with working fishing boats alongside the tourist infrastructure.
Spetses has excellent beaches — more varied and sandier than Hydra — particularly on the southern coast accessible by water taxi. Agia Paraskevi beach is long and organized; Xilokeriza is wilder and more beautiful. The island’s Bourtzi headland, with its seafront path and views back to the town, is excellent for evening walks. Spetses played a crucial role in the Greek War of Independence, particularly through the naval commander Laskarina Bouboulina — one of Greece’s most celebrated revolutionary heroes, a woman who commanded her own fleet. Ferry: Flying Dolphin from Piraeus 2 hours 15 minutes; conventional ferry 3.5 hours. Book through Ferryscanner.
The Combined Island Tour: Aegina, Poros, and Hydra in One Day
The classic organized day trip from Athens visits all three islands — Aegina, Poros, and Hydra — in a single day on a cruise boat that departs Piraeus in the morning and returns in the evening. This format gives you 1-2 hours on each island: enough to walk the harbors, eat lunch on one, swim briefly on another, and get the general impression of each. It is not enough to understand or properly experience any of them. But as an introduction to the Saronic islands — particularly for travelers on a tight itinerary who want to see more than Athens alone — the combined tour is genuine value. Book through GetYourGuide for the best-reviewed operators, or through Viator which also has good options. The TripAdvisor reviews for specific boat tour operators are worth reading before booking.
Practical Information: Getting to the Saronic Islands
All Saronic island ferries depart from Piraeus port — specifically from Gate E8/E9 (the Saronic gulf departure area, separate from the Cyclades gates). From central Athens, take Metro Line 1 (Green Line) to Piraeus station, then walk or take a taxi to the Saronic ferry gates (10-15 minutes). See our Athens transport guide for full metro and Piraeus navigation details.
Two ferry types operate the Saronic routes: Flying Dolphins (high-speed hydrofoils, no outdoor deck, faster and slightly more expensive) and conventional ferries (slower, cheaper, outdoor deck space). For day trips where time matters, the Flying Dolphin is worth the premium. For leisurely overnight visits, the conventional ferry is fine. Book all tickets through Ferryscanner — multiple operators serve these routes and prices vary.
For staying connected throughout the islands without worrying about roaming charges, an eSIM from Airalo covers Greece and works seamlessly across all the Saronic islands — activate before you leave home. For accommodation on any of the islands for an overnight stay, search through Booking.com — Hydra and Spetses in particular have excellent boutique hotel options in historic buildings.

Aegina — 35 minutes by Flying Dolphin from Piraeus. It’s the most accessible island day trip from Athens and one of the most rewarding, combining the Temple of Aphaia, good beaches, and excellent local products.
Can you do a Greek island as a day trip from Athens?
Yes — Aegina (35 min), Poros (2 hours), and Hydra (1 hour 40 min) are all easily doable as day trips. Aegina is the most practical day trip. Hydra is worth an overnight stay to experience the island after the day boats leave. Book ferries through Ferryscanner.
Is Hydra worth visiting from Athens?
Absolutely — Hydra is one of the most beautiful and distinctive islands in Greece. No cars, no motorcycles, historic mansion architecture, excellent swimming, and an authenticity that the famous Cyclades increasingly lack. Worth at least one night rather than just a day trip.
How much does it cost to visit the islands near Athens?
Ferry to Aegina: €9-12 one way (Flying Dolphin). To Hydra: €25-30. To Poros: €15-20. To Spetses: €30-35. Combined day tour (Aegina + Poros + Hydra): €60-80 per person including boat, guide, and sometimes lunch. See current prices on Ferryscanner.
Are the islands near Athens worth it compared to the Cyclades?
For different reasons — yes. The Saronic islands (particularly Hydra) offer authenticity and historical character that the most famous Cyclades have partially lost to mass tourism. They’re also significantly cheaper, much closer, and easier to combine with an Athens visit. For the postcard Aegean aesthetic, the Cyclades win. For genuine Greek island character, Hydra competes with anything.
