A sample week from Kifisia

One idea mixing city, nature and rainy-day backups — swap cards freely. Delphi + Arachova (1 night) can replace Fri–Sat.

Minivan transfer ATH → Kifisia. Evening stroll in Kefalari Square.

Morning Wednesday laiki market; Goulandris museum (09–16); afternoon rest.

Metro to Akropoli: Acropolis Museum (or Acropolis 08:00 if elevator OK); Journey of Wool workshop; ~17:00 Strofi rooftop dinner; taxi/metro back.

Tatoi grounds walk + picnic (dry day) or Parnitha cable car. Rain? Hellenic Cosmos (open Fri 10–20).

Marathon Tomb/museum, Lake Marathon dam view, Schinias walk, fish lunch in Rafina. (Goulandris free entry if not yet visited — verify.)

Monastiraki flea market (busiest Sunday), Ancient Agora, Plaka Happy Train. Or Allou Kidom from 10:00.

Planetarium or Benaki Toy Museum (Thu–Sun only — so Mon = Planetarium); Kifisia organic market 14–18.

Attica Zoo near the airport (09:00–sunset) if the flight allows.

Hours and facts come from each linked card’s sources.
