Athens rewards an early start and a good pair of shoes. On my trip the whole center turned out to work as one loop you can walk in a single day: the Acropolis first thing before it gets hot, down through Plaka, up the market street for pies and coffee, then a quiet garden dinner to finish. The route is dense with shops the whole way, ceramics and leather and olive wood and little design stores, so it doubles as a wander.
This is exactly how I would spend one day in Athens, in the order I would walk it again, with the food, the shops, and the honest notes along the way.

Before you go
Athens is walkable and sunny for most of the year, with spring and fall the easiest times to walk it. Fly into Athens International (ATH); it is worth checking a few dates for the best fare, and a short travel-insurance line is smart for a trip that mixes a city with the islands.
Getting from the airport is simple: the X95 bus runs 24 hours to Syntagma Square (about 5.50 euros, buy the ticket at the kiosk before you board), and from there it is a short taxi to your hotel. More on taxis at the end.
Morning: the Acropolis before the crowds
The Acropolis
Start here at the 8am opening. It is the one unmissable thing in Athens, and the early slot is the difference between quiet photos and a crush. Enter at the South Slope Gate, the Theatre of Dionysus entrance across from the Acropolis Museum, which is far calmer than the main west gate. Head straight up to the Parthenon for 15 to 20 minutes to yourself before the tour groups arrive, then wander back down past the Theatre of Dionysus and the Odeon of Herodes Atticus, sights the main-gate crowd walks right past. Book a timed ticket ahead on hhticket.gr, since it sells out in summer.
If you would rather have the history brought to life, a small-group guided walk is worth it. A licensed guide takes you up through the monuments, the Theatre of Dionysus, the Odeon of Herodes Atticus, the Propylaea, the Temple of Athena Nike, the Parthenon, and the Erechtheion, and skips you past the ticket line, with an option to add the Acropolis Museum at the end. Book the early slot to stay ahead of the heat; budget about four hours if you include the museum.
Acropolis Museum
Right across from the South Slope gate, so it pairs naturally with the morning. Book a timed online ticket and give it an hour.
Midday: Plaka and the central market
Walk down into Plaka, the oldest part of the city, all narrow lanes and shops, then head up Athinas Street toward the market. This stretch is liveliest in the morning and early afternoon, so do not leave it too late.
Varvakios Central Market
The old meat and fish market, loud and real, with herb and spice stalls in the streets around it. Worth walking through even if you are not buying. Closed Sundays.

Creme Royale
Across from the market and one of the best Greek pie spots in the city. Get the spinach pie and a bougatsa, the phyllo pastry filled with warm cream. Have a proper bougatsa at least once while you are in Greece.

Mokka Specialty Coffee
Right by the market. Order the traditional Greek coffee brewed in a briki over hot sand, a small ritual worth stopping for.

The streets around the market are full of little food shops, honey and olives and spices, worth slowing down for. My exact favorites, down to the stall, are in the printable guide.
Afternoon: Monastiraki and Aiolou Street
Monastiraki Flea Market
Browse the stalls along Ifestou Street. Look for Olive Land Shop for olive-wood boards and utensils that actually last.

Ristorante Atlantikos
A short walk from Monastiraki square, this is affordable seafood done well. Order the fried small shrimp, some of the best bites of my trip.
Tylixto Greek Wrap
One of the best gyro spots, and it gets going in the evening. Honest take: the meat gyro was just okay for me, but the vegetarian one with roasted eggplant was genuinely delicious, so get that one.

Lukumades
Right next door to Tylixto, and one of the best places in Athens for loukoumades, the Greek fried donuts. Light, airy, not greasy. A must while you are in Greece.
The Pinnacle Athens Rooftop
Also on Aiolou. The rooftop is small and quiet, with a lovely Acropolis view at sunset, and I came up for dessert. If you want a livelier scene, plenty of other rooftops deliver it, but this one is calm.
Evening: Mitropoleos and a garden dinner
Walk south toward Mitropoleos for the last little cluster.
Yogu Lab
Thick, real Greek frozen yogurt, and an easy stop on the way to dinner.
Ergon House
Across from Yogu Lab, a hotel with a restaurant and a lovely little market inside. A good place to pick up pretty olive-oil tins and totes for gifts.

Yphes
Around the corner and my favorite dinner in Athens: modern Greek food in a quiet garden. It is known for dinner rather than breakfast, and it is worth booking ahead.
Two experiences worth booking
If you have more than a day, two things go deeper than the walk:
Athens food walking tour
A morning food walk through the market and the center, and the best orientation you can get to how Athenians actually eat. Book it early in your trip so the rest of your eating makes more sense.
The Greek Kitchen cooking class
A hands-on Greek cooking class with a market visit, a few minutes from the central market. You shop, then cook a full Greek spread and sit down to eat it.
Where to stay
Base yourself near Monastiraki or the central market and you can walk this whole loop from the door. I stayed at three hotels, and my favorite was Acropolis The Grid Athens Hotel, right by the market and in the middle of the route. The Pinnacle Athens has that quiet rooftop sunset view; honest note, I did not love the rooms, but the view is worth a drink even if you sleep elsewhere.
Getting around
The X95 bus runs 24 hours from the airport to Syntagma Square (about 5.50 euros, bought at the kiosk before boarding), then a short taxi to your hotel. For city taxis, always ask the driver to run the meter before you get in. A “1” on the meter is the day rate and a “2” is the night rate, and about 1.5 km should run around 5 euros. Most drivers were great; one tried to charge a flat 10 euros for a short ride with the meter off, so just confirm it is running before you start.
