This 3 days in Athens itinerary covers the city's unmissable ancient sites, its best museums and neighbourhoods, and a sunset finale at the Temple of Poseidon — with euro costs, seasonal weather and a Google Maps link for every stop. Athens is bigger than its ruins: each day groups one area together so you're not criss-crossing the city, starting before the tour buses at the Acropolis and ending with a swim on the Athens Riviera. Three days is the sweet spot — enough for the classics at an unhurried pace, with time left over for the taverna-and-neighbourhood Athens locals actually live in.
April to early June and September to October are ideal: warm, walkable weather and thinner crowds at the big sites. July and August are hot (often above 34°C) and busy — do the Acropolis at opening and siesta in the afternoon. Winter is mild, quiet and cheap, though some island ferries and Riviera beach clubs scale back.
The metro is fast, cheap and air-conditioned, and the airport line reaches Syntagma in 40 minutes. Most of the centre (Plaka, Monastiraki, Psyrri, Kolonaki) is walkable. The tram runs from Syntagma down the coast to the Athens Riviera, and buses or tours reach Cape Sounion — taxis and ride-hailing (FREE NOW) are affordable and plentiful.
Morning
€20 summer / €15 winter; €30 combined ticket
Be at the entrance when it opens at 08:00 (summer) and walk straight to the Parthenon before the heat and the crowds, then the Erechtheion's Caryatids, the Propylaea and the Nike Temple. The marble is polished and steep — grippy shoes and water are essential, and there's almost no shade.
Acropolis of Athens, GreeceAfternoon
€10 (covered by combined ticket); lunch €12–€20
Walk down through Monastiraki to the Ancient Agora, the commercial heart of the ancient city — the beautifully preserved Temple of Hephaestus and the rebuilt Stoa of Attalos are the highlights, and it's covered by the combined ticket. Lunch afterwards in Monastiraki's market streets or a rooftop taverna with Acropolis views.
Ancient Agora of Athens, GreeceEvening
Free; dinner €15–€30
Climb the whitewashed island-village lanes of Anafiotika tucked under the Acropolis, then wander Plaka's neoclassical streets as the lamps come on. Cross into Psyrri for dinner where tavernas spill onto the squares — order moussaka, grilled octopus and a carafe of house wine.
Anafiotika, Plaka, Athens, GreeceMorning
€12
Spend the morning with the world's greatest collection of Greek antiquities — the gold Mask of Agamemnon, the Antikythera mechanism, the bronze Zeus (or Poseidon) — in one of Europe's finest museums. Two focused hours beats trying to see everything; the sculpture galleries are the don't-miss rooms.
National Archaeological Museum, Athens, GreeceAfternoon
Free; lunch €12–€25
Time Syntagma Square for the changing of the Evzone guards at the Parliament (on the hour; the full Sunday ceremony at 11:00), then take the funicular or stroll up through chic Kolonaki, stopping at the Benaki or Museum of Cycladic Art if you have energy left. Lunch on a Kolonaki terrace is people-watching at its best.
Syntagma Square, Athens, GreeceEvening
€10 funicular return; dinner €15–€30
Take the Lycabettus funicular (or the 20-minute footpath) up the city's highest hill for the classic panorama: the Acropolis, the Saronic Gulf and, on clear days, the mountains of the Peloponnese at sunset. Head down to Exarchia or Kolonaki for dinner — the hilltop café is scenic but overpriced.
Mount Lycabettus, Athens, GreeceMorning
€1.20 tram; coffee €3–€5
Ride the tram from Syntagma down the coast to Flisvos Marina or continue to Vouliagmeni for a first look at the sea — a beach walk along the boardwalk and coffee at a marina café. The Riviera is how Athenians spend their weekends, and it resets the pace after two days of ruins.
Flisvos Marina, Paleo Faliro, Athens, GreeceAfternoon
€20 lake entry; lunch €20–€35
Swim in the Vouliagmeni Lake, a warm mineral lagoon in a rock-ringed crater that stays around 24°C year-round, or pick one of the organized beaches further along the coast. Have a late seafood lunch at a waterside taverna in Vouliagmeni — grilled fish and a Greek salad with your feet near the water.
Vouliagmeni Lake, Vouliagmeni, GreeceEvening
€10; tour with transfer €35–€55
Drive or take an afternoon bus/tour down the coast road to Cape Sounion, where the marble columns of the Temple of Poseidon stand on a cliff 60 metres above the Aegean — Byron carved his name here, and the sunset is the best finale in Attica. Get there 90 minutes before sundown and have dinner at a seaside taverna on the way back.
Temple of Poseidon, Cape Sounion, GreeceMid-range estimate: a central room in Koukaki, Exarchia or Psyrri, one taverna meal and one café meal a day, plus site tickets and public transport. Boutique hotels in Plaka or Kolonaki can double this; the €30 combined archaeological ticket spreads across several of the sites below.
Estimated daily total
€70–€160 per person, per day
