Quick answer: Three days in Athens covers the Acropolis and ancient sites, the Plaka and Monastiraki, and a sunset day trip — here’s the plan.
Athens’ ancient core is compact and walkable. This 3-day plan balances the must-see ruins with the city’s lively neighbourhoods.
The itinerary, day by day
Day 1 — The Acropolis & Plaka
Visit the Acropolis and Parthenon early to beat crowds and heat, then the Acropolis Museum. Wander the Plaka and tiny Anafiotika, and have dinner under the lit-up Acropolis.
Day 2 — Ancient Athens & Monastiraki
Explore the Ancient Agora and Roman Agora, browse Monastiraki’s flea market, catch the changing of the guard at Syntagma, and stroll the National Garden.
Day 3 — Views & a day trip
Climb Lycabettus Hill for the best views, see the National Archaeological Museum and the Panathenaic Stadium, then head to Cape Sounion for sunset at the Temple of Poseidon.
Where to stay & when to go
Stay in Plaka or Monastiraki to walk everywhere, or Koukaki near the Acropolis Museum. Visit in spring or autumn to avoid the summer heat, then pair Athens with the islands.
