Athens in 3 days

Cape Sounion sits at the southern tip of the Attica peninsula, a 65-metre limestone headland above the Aegean, 70km south of Athens. The Temple of Poseidon was built 444–440 BC during the same Periclean building programme that produced the Parthenon; its architect — the same who designed the Temple of Hephaestus in the Ancient Agora — left his name to history unrecorded. Of the original 34 Doric columns, 15 still stand, the marble worn nearly white by two and a half millennia of sea wind. The site opens daily at 9:00 and closes at sunset (around 20:30 in summer, 17:00 in winter); admission is €10, reduced to €5 for students. The KTEL bus from Pedion Areos Park runs roughly hourly at €7 each way. The coastal Route 91 along the Attica Riviera — coves, pine slopes, low-key beach clubs — is half the pleasure of the trip; rent a car if you can manage it. Byron visited in 1810 and scratched his name into the marble. It's still legible on the inner face of the pronaos wall near the entrance, low on the stone — worth finding before anyone tells you where to look. Aim to arrive by 17:00 in summer. The temple faces west, and as the light drops the columns go amber then deep orange against the water — the same silhouette Greek sailors watched for on the voyage home from the east. Afterwards, walk down to the small harbour at Sounio for grilled octopus and cold Assyrtiko at one of the fish tavernas. Better and cheaper than anything sold on-site. Insider tip: before the temple, take the perimeter path around the headland. On a clear day, Athens shimmers at the far end of the Saronic Gulf — a perspective most visitors miss entirely.

Founded in 1829 and housed since 1893 in a neoclassical building designed by Ludwig Lange and completed by Ernst Ziller, the National Archaeological Museum sits on Patision — a grittier, lived-in Athens well north of the Plaka circuit, bookended by anarchist Exarcheia to the west and the Polytechnic to the south. The collection runs from Neolithic (7,000 BC) through to the Byzantine era across 11,000 objects. The Gold of Mycenae gallery anchors the visit: the Mask of Agamemnon (1550–1500 BC), the golden death mask Schliemann misidentified in 1876 — it predates the Trojan War by three centuries — alongside inlaid bronze daggers, golden cups and grave goods that make the Shaft Grave civilisation suddenly tangible. The Antikythera Mechanism, retrieved from a Roman-era shipwreck off Crete in 1901, sits in its own darkened case: 37 interlocking bronze gears that computed solar and lunar cycles and predicted eclipses, assembled around 150–100 BC. The Bronze Age Thera frescoes from Akrotiri — sealed by the Santorini eruption c.1627 BC — are the finest Minoan murals outside Crete, their colours intact after three and a half millennia underground. Open Tuesday–Sunday 08:00–20:00, Monday 13:00–20:00. Admission €12, reduced €6. Arrive at opening: the Mycenae room is yours alone before tour groups descend around 10:30. Eat afterwards on Themistokleous in Exarcheia — grilled fish, horiatiki, carafe wine, no laminated menus in sight.

Buried half a floor below street level in the Athinas Market district, Diporto tis Athinas has been feeding Athenians since 1887 — butchers, merchants, and market traders who have eaten here for generations, and still do. The name means "the two-doored"; there is no sign to help you find either of them. Look for a narrow staircase descending from Sokratous 9, a weathered door, and the smell of garlic and olive oil. Inside: rough stone walls, wine barrels stacked to the ceiling, bare wooden tables, and light so dim your eyes need a moment. There is no menu. The owner moves between tables and tells you what exists that day. Expect gigantes — giant baked beans slow-cooked in tomato sauce, a version that makes every other rendition in the city feel approximate — revithia (chickpea soup), tirokafteri (spicy feta dip), boiled greens dressed with olive oil and lemon, and whole grilled fish when it is available. Order the house wine by the carafe; it arrives in a clay jug and costs almost nothing. A full lunch with multiple dishes, bread, and wine comes to around €12–15 per person. Open Monday to Saturday, roughly 08:00 to 17:00; arrive before 13:00 if you want a seat, since the surrounding Varvakios meat and fish market empties into these benches at noon. Cash only, no reservations. The neighbourhood is working Athens at its most unvarnished — wholesale butchers, spice traders, the smell of the fish hall two streets over. Diporto sits at the centre of it, unchanged in a way that has nothing to do with preservation and everything to do with the fact that nobody has found a reason to improve it.

Lake Vouliagmeni sits 25 kilometres south of central Athens, where a seismic collapse opened the roof of an ancient sea cave to the sky. The result is a brackish pool, connected to the Saronic Gulf by an underground channel and held at 22–29°C year-round by a thermal spring. The Greek state organised it as a therapeutic resort in the 1930s; Athenians had been treating skin and joint conditions here considerably longer. Entry costs around €15 for adults, with reductions for children and over-65s. Gates open at 8:00 and close around 8:00 PM in summer, shorter hours from October to April. Float toward the far end where the thermal channel runs warmest — the slight salinity lifts you higher in the water than you expect. The resident grey mullet will investigate motionless legs within minutes; it's less gimmick than it sounds and works noticeably well on dry skin. The lakeside café handles cold drinks and a basic mezedes plate. For a proper meal, the marina strip five minutes up the road has small tavernas doing grilled tsipoura at honest prices — order the octopus if the board shows it. The neighbourhood is the quietest stretch of the Athens Riviera: umbrella pines and old-money villas rather than the beach-club noise further north toward Glyfada. The A2 bus from Glyfada reaches the stop outside in about 20 minutes, making a car unnecessary. On summer weekends arrive before 9:30 or sunbeds go fast; Tuesday mornings, the place is nearly empty.

Plaka (Πλάκα) spreads across the northern slope of the Acropolis, continuously inhabited since at least the Bronze Age. Its street plan is largely Ottoman (1458–1833) — a layering visible on every block: Byzantine chapels embedded in later stonework, neoclassical mansions from the Bavarian period, Roman column bases jutting from taverna courtyards. The quietest quarter is Anafiotika, a Cycladic village transplanted here in the 1840s. Craftsmen from the island of Anafi — recruited to build King Otto's palace — invoked an Ottoman-era law permitting islanders to build freely and constructed whitewashed cube houses on the near-vertical rock face exactly as they would at home. Climb the stepped lanes off Stratonos before 9am to have the bougainvillea and chapels entirely to yourself. The Roman Agora (Pelopida Street entrance; daily 8am–8pm in summer, €8 or included in the €30 Acropolis combined ticket) holds the 1st-century BC Tower of the Winds: an octagonal marble timepiece by the Macedonian astronomer Andronikos of Kyrrhes, its eight carved wind gods still crisp enough to identify — Boreas (north) at twelve o'clock, Notos (south) opposite. On Adrianou, skip the tourist cafés: Scholarchio (Tripodon 14) serves honest mezedes — stuffed vine leaves, taramosalata, grilled halloumi — at €10–14 a head. The sesame koulouri cart at the Lysikratous corner charges €0.50 for breakfast. Insider: the Lysikrates Monument (334 BC, Lysikratous Street) is the world's oldest surviving exterior with Corinthian capitals and almost always unattended — free to walk around at any hour.

Psiri (Ψυρρή) sits directly north of Monastiraki, wedged between the Ermou tourist strip and the neighbourhood of Gazi — a former leather-working and metalworking quarter with artisan roots reaching back to the Ottoman period. The creative transformation began in the early 1990s, when Athenian artists and bar-owners moved into crumbling workshops around Plateia Iroon (Heroes' Square), the neighbourhood's central piazza; the process accelerated sharply after Athens hosted the 2004 Olympics. Enough of the original trade survives to feel genuine: working smiths and shoe-repair shops still occupy the backstreets between the bars. The standout daytime stop is a Kriti (Κρήτη) Cretan pastry shop — typically open 07:00–17:00 — selling spanakopita and tiropita by the slice for €1.80–2.50 each. Still warm from the oven in the morning, sold cold and perfectly good by noon. For souvlaki, local preference runs to kalamaki: skewered pork or chicken served without pita, eaten standing at the counter for around €2–2.80 a skewer. Order grilled peppers and a small tzatziki on the side; avoid the chips. Most souvlaki shops run 12:00–22:00, with a lull around 16:00. After dark, Psiri shifts register entirely. The same streets fill with mezedopolia (small-plates tavernas) and cocktail bars from 21:00 onward; Agion Anargyron Street has the densest concentration of pavement tables. Insider note: come for lunch on a weekday — weekend evenings draw enough tourist overflow from Monastiraki that both the atmosphere and the quality of attention noticeably thin out.

Lycabettus Hill (Λυκαβηττός) rises 277 metres from central Athens — pine-covered limestone standing a hundred metres above the Acropolis. The whitewashed Chapel of Agios Georgios at the summit dates to the 19th century, built on a site sacred since Byzantine times. The cable car (τελεφερίκ), opened in 1965, departs from upper Aristippou Street in Kolonaki — Athens's smartest neighbourhood, worth exploring for coffee and boutiques — and reaches the top in three minutes. Daily 09:00–00:00 in summer, shorter hours October–March; return €7. The stepped footpath takes 25 minutes and is the better approach. At the summit: Orizontes restaurant serves modern Greek food with the most dramatic table setting in the city — book a window seat for dinner, when the Acropolis is floodlit and the crowds have thinned. The open-air Lycabettus Theatre below the summit has hosted international concerts since the 1960s, running June–September. The panorama places the Acropolis directly southwest, close enough to read individual columns; beyond it, the Saronic Gulf and on clear days Aegina and Hydra. Attica's plain spreads in every direction, ringed by Hymettus, Penteli and Parnitha. Arrive 30 minutes before sunset, then stay. The cable car crowds disperse the moment the sun drops; 45 minutes later the hilltop is nearly empty, the city lighting in waves below — that second hour is the real reward.

Greek coffee (ελληνικός καφές — the same as Turkish coffee, though no kafeneio owner in Athens will thank you for the comparison) arrives preceded by a glass of cold water: always the water first, to clear the palate. The coffee itself is finely ground Arabica boiled in a long-handled copper pot — a briki — over a gas flame, with sugar worked into the brewing rather than added after. You specify your sweetness before the pot goes on: sketos for none, metrios for one heaped spoon dissolved into the boil, glykos for two. It is poured unfiltered and left to settle for a full minute before the first sip. The grounds stay in the cup. The ritual is unhurried by design. The kafeneios of Kolonaki occupy a specific register of Athenian life. This neighbourhood — climbing the lower slopes of Lycabettus, its streets threaded with embassies, contemporary galleries, and boutiques that don't display prices — is not the coffee culture of Monastiraki or the Plaka. It is the daily social infrastructure of a district where architects, journalists, and constitutional lawyers have been conducting the same arguments since the postwar decade. Tables overflow onto narrow pavements; tavli boards materialise without being asked; a radio plays something nobody is actively listening to. The kafeneio typically opens around eight in the morning and does not close before midnight, the afternoon extending, characteristically, well past itself. A Greek coffee here runs €2.50–3.50 depending on the house. Order metrios if uncertain — it meets the bitterness of the roast halfway. Come between ten and noon when the morning papers are still being parsed at adjacent tables, or after nine in the evening when the same chairs fill again. If the kafeneio keeps trigona — the honey-and-cream pastries from northern Greece — order one; if not, the koulouri vendor passes most mornings with sesame rings for a euro. Insider note: the grounds remaining in your upturned cup are readable. Leave the cup inverted on the saucer for five minutes, hand it to the right person, and you will receive an interpretation. Whether you believe it is beside the point.
