Athens as a Base: 3 Days on a Budget
Three days: settle in, one island, one sunset
Three days buys you a real Greece-gateway sampler: a logistics day, a Saronic island, and Cape Sounion at sunset. Athens itself is the base here, not the destination; the in-city 3-day itinerary covers the Acropolis and museums if that is what you actually want. Other lengths of this trip: 2 , 4 , 5 , 6 , and 7 days .
Book these before you go:
- Piraeus-Aegina ferry ticket , 9-20 EUR one-way; peak-season sailings fill up.
- Athens hotel near Monastiraki or Omonia , both sit on the Piraeus-bound Metro Line 1.
- Cape Sounion sunset tour if you would rather not manage the KTEL bus schedule.
| Day | Focus | Distance / travel time from Athens |
|---|---|---|
| 1 | Athens: arrival and logistics | base |
| 2 | Aegina (Saronic island) | ~40 min-1h15 by ferry |
| 3 | Cape Sounion sunset | ~1-1.5h by bus/car |
Day 1: Athens, logistics only
Land at Athens International Airport, about 27km southeast of the center. Metro Line 3 reaches Syntagma or Monastiraki in about 40 minutes for 9 EUR full fare; the X95 bus covers the same route for roughly 5.50 EUR in 60-90 minutes depending on traffic. A single transit ticket is 1.20 EUR, valid 90 minutes across metro, bus, and tram.
Base yourself near Monastiraki or Omonia, both on Metro Line 1 to Piraeus, so tomorrow’s ferry morning does not eat an extra 20 minutes of crosstown transit. Buy your Aegina ferry ticket online tonight, and check the OASA transit site for any service disruptions before you commit to a schedule.
Day 2: Aegina, an actual island in a day
Aegina is the cheapest, most frequent Saronic crossing: a conventional ferry runs 70-75 minutes for roughly 9-14.50 EUR, or a catamaran covers it in about 40 minutes for 15-20 EUR. Check current Saronic route schedules before you commit to a sailing. Walk the harbor town, buy a bag of local pistachios, and see the Temple of Aphaia if the schedule allows. Confirm your return sailing before you leave the dock; Sunday and off-season schedules thin out fast.
Day 3: Cape Sounion, the closest real day trip
KTEL Attikis runs a public bus to Sounio from the Mavromateon Street terminal, roughly 7-9 EUR one-way, about 2 hours each way. A sunset tour costs several times that and the roughly 20 EUR site entrance is usually charged separately either way. Go for sunset, not a midday visit: the Temple of Poseidon over the sea at dusk is the entire point, and Lord Byron’s carved graffiti is still visible on a column. The ruins themselves take 30-45 minutes; the coastal drive and the wait for the light are the real trip, so plan to leave Athens by mid-afternoon.
Is the Sounion bus worth the extra hour over a tour?
Yes, on a budget trip. The KTEL bus costs a fraction of an organized sunset tour and covers the same coastal route via Glyfada, Vouliagmeni, and Varkiza, just without a guide narrating it. The only real advantage of the tour is fixed timing built around sunset; if you can read a bus schedule and plan your own departure, the public bus gets you the same view for far less.
Can you add Santorini or Mykonos to a 3-day trip?
No. Santorini’s fastest catamaran alone runs 4h50-5h one-way; Mykonos averages roughly 3h49 at best. Either eats most of a day each direction by sea, and flying, about 45 minutes, still only buys a rushed single afternoon. With just 3 days already split between Athens, Aegina, and Sounion, treat the Cyclades as a reason to come back with at least 2 extra nights, not a stop to squeeze in here.
Carry cash for Aegina’s smaller tavernas and the Sounion snack stands; card readers are not universal outside central Athens.
