People think of Luxembourg City as a flat little financial capital. It's built on cliffs. The old town sits high above the Grund and the Alzette valley, so you'll climb a lot, and with rain on 9 to 15 days every month, a good rain layer matters more than a nice coat.

What shoes should you pack for Luxembourg City?
The city is steep. Getting from the Ville Haute down to the Grund means stairs, cobbles and slopes, though the free Pfaffenthal lift helps. Wear waterproof walking shoes with grip, because wet cobbles are slippery and knit sneakers soak through here.
What do people wear in Luxembourg City?
It's a business town, and weekday crowds in the center dress smart, with dark coats, good shoes and not much athleisure. Evenings out are smart casual. Dark layers and a decent rain jacket will blend right in.
What plugs does Luxembourg City use?
Luxembourg uses type C and F plugs at 230V, the same as Germany. Travelers from the US, UK and Australia need an adapter. Most phone and laptop chargers handle 230V, but check any hair tools you bring from the US.
