Is August worth it in Athens?
Peak weather and peak crowds — the classic trade-off; you pay for the season in queues, not in the weather. For better value, come in May or October.
Book beds and the big-ticket sights well ahead, and start your days by eight — in a month this full, the early hours are the only uncrowded ones.
