Athens is an immensely walkable city. Still, should you decide you want to ride—or should Mother Nature not be as accommodating to your desires as you’d like—you’ll do well to check out bus #400, OASA‘s (the public bus system’s) “sightseeing line.”
You can buy your ticket for €5 on the bus itself. Your ticket will be good for 24 hours, so you can get on and off the bus wherever you like. You can even start your tour on one afternoon and continue it the following morning if you find yourself shifting into “chilling-for-five-hours-at-a-local-café-and-then-heading-to-the-taverna” mode. We’ve been there.
The bus makes stops at many popular sites and cruises through neighborhoods of greatest interest to most tourists, including the National Archaeological Museum, Monastiraki, the Benaki Museum, and Plaka. No, there is no Vince Vaughn character on the bus offering funny asides about the city’s history and people, but bus #400 provides easy and inexpensive access to places you’ll want to go.
