Suppose you find yourself with an extra day in Athens: not quite enough for a break to Mykonos or other Aegean island, but too tempting to not make a breezy break from the pavement. Try Aegina: it’s just 35 minutes from Piraeus port by hydrofoil and a world away from the urban congestion. The first must is a visit to the Temple of Aphaia ; amazingly well-preserved. You’ll feel like you’re on a private tour of the Parthenon. The second thing is pistachios: Aegina is famous for ‘em, so stock up. And of course, for those picturesque coastlines that no place does quite as well as Greece can.
