Acropolis at Sunrise
Book the first ticket slot (8am) and climb the Acropolis before the heat and crowds arrive. The Parthenon in morning light is one of the great experiences in world travel.
Acropolis Museum
One of Europe's finest museums, built directly above archaeological remains — the Parthenon Gallery on the top floor shows the surviving frieze with views of the actual hill through floor-to-ceiling glass.
Athens Street Food Tour
Souvlaki at Thanasis in Monastiraki, spanakopita from a bakery, loukoumades (honey doughnuts), and Greek coffee at a traditional kafeneion — Athens feeds you well for almost nothing.
Cape Sounion Day Trip
The Temple of Poseidon at the edge of the Attica peninsula, where Byron carved his name. The sunset over the Aegean from the clifftop temple is extraordinary.
National Archaeological Museum
The finest collection of ancient Greek artefacts in the world — the Antikythera Mechanism, the Mask of Agamemnon, and countless objects that reframe everything you thought you knew about antiquity.
Plaka Neighbourhood Walk
Athens' oldest neighbourhood — a maze of narrow, pedestrian lanes beneath the Acropolis, lined with neoclassical houses, bougainvillea, tavernas, and small museums. The most charming part of the city to wander.
