Athens and one island: five days that actually work
Three days in Athens and two on an island you can reach before lunch — with the Acropolis timing that avoids both the queue and the heat.

Athens is a three-day city with a two-day island attached, and the mistake most people make is doing it the other way round: a week on a famous island and a rushed afternoon at the Acropolis on the way home.
Five days splits cleanly. Three in the city, which is genuinely enough, and two somewhere you can reach on a morning ferry.
The Acropolis: price, cap, and the hour that matters
The Acropolis now costs €30 for adults and €15 reduced, the same price all year. Entry is timed, the site admits a maximum of 20,000 people a day, and in July and August the slots sell out five to seven days ahead. This is the one thing to book the moment your flights are confirmed.
Take the first slot of the day, at eight. Three reasons: the marble is not yet hot, the light on the Parthenon's east face is better, and during recent heatwaves the site has closed in the early afternoon when temperatures climbed — a first slot is the one that never gets cancelled.
The €30 also buys you the archaeological site, not the museum. The Acropolis Museum, at the foot of the hill, is a separate and much cheaper ticket, and it is the better building: the top floor is laid out to the exact dimensions of the Parthenon, aligned with the real thing through the glass.
Getting in from the airport
Athens airport is 33 km east of the city and there are two sensible ways in.
| Option | Where it goes | Time | Price |
|---|---|---|---|
Metro line 3 (blue) | Syntagma and Monastiraki, direct | About 40 min, every 30 min | €9 single, €16 return |
X95 express bus | Syntagma, 24 hours a day | 60–90 min in traffic | €5.50 |
Taxi | Flat fare to the centre | 40 min | Fixed day and night rates |
The metro runs roughly 06:30 to midnight. Outside those hours the X95 is the only public option, and it runs all night, which is why it exists.
Day one: the rock, the old town and the hill at sunset
Acropolis at eight, Acropolis Museum at eleven, lunch in Koukaki — the neighbourhood behind the museum, where Athenians eat.
In the afternoon walk the Ancient Agora, which is where the city actually happened: Socrates, the law courts, the stoa. It is included in the multi-site ticket if you buy one, and it is far emptier than the Acropolis above it.
End on Filopappou Hill, ten minutes' walk and free, for the sunset view back at the Parthenon. This is the photograph everyone wants and almost nobody queues for.
Day two: the museum most people skip
The National Archaeological Museum, north of the centre, is one of the great museums of the world and is routinely skipped by people who have already "done" the Acropolis. The Mycenaean gold, the Antikythera mechanism and the bronze of Poseidon are all here. Give it two hours.
Spend the afternoon in Psyrri and Monastiraki — the flea market on Sunday morning, the coffee culture the rest of the week — and the evening in Exarchia or on a Petralona rooftop.
Day three: pick your version of Athens
- Cape Sounion — the Temple of Poseidon on a cliff over the Aegean, 90 minutes by bus down the coast, best in the last two hours of light.
- The Riviera — the tram south to Glyfada and a swim at one of the organised beaches, which is what Athenians do in summer.
- Kerameikos and the Gazi district — the ancient cemetery, then the industrial quarter that became the nightlife.
Days four and five: which island
The distinction that matters is the port. Most ferries leave from Piraeus, 30 minutes from Syntagma on metro line 1. Rafina is smaller, closer to the airport, and serves Andros, Tinos and Mykonos.
| Island | Time | Good for |
|---|---|---|
Aegina | About 40 min by fast ferry | A day trip; pistachios and a temple |
Agistri | About 55 min | Pine forest and swimming, almost no cars |
Poros | About 1 hour | Close, green, walkable town |
Hydra | About 1 hour 30 | No cars at all, donkeys and stone lanes |
Paros or Naxos | 3 to 4 hours | A proper two-night island with beaches |
For two nights, Hydra is the one that feels furthest from a city you left ninety minutes ago: vehicles are banned, the harbour is an amphitheatre of stone houses, and there is a swimming platform on the rocks beyond the town.
If you want sand, take Naxos instead — bigger, cheaper, with a mountain village interior and the best beaches within reach of Athens.
Book ferries in advance in summer, and check the forecast. The meltemi, the north wind that blows through July and August, cancels sailings — mostly the small fast boats, rarely the big car ferries. Do not plan a same-day return connection to a flight.
Practical notes
Athens transport is one ticket system: €1.20 buys 90 minutes on the metro, buses and the tram, with transfers included. The airport is the exception and needs its own ticket. Validate at the gate or the machine on board.
August is the hottest month and the month Athenians leave. Many neighbourhood tavernas close for two or three weeks. April, May, late September and October are warm, cheap and half-empty — and the sea is still swimmable into October.
Tipping is rounding up, not a percentage. Tap water in Athens is safe to drink; on the islands it often is not, and everyone drinks bottled.
