Amsterdam

The bike is the thing to understand about Amsterdam before anything else. There are more registered bicycles than people in the city, and the infrastructure reflects it — dedicated lanes with their own traffic signals, running alongside and sometimes taking priority over car lanes. Pedestrians who drift into a bike lane without checking get a bell, and sometimes a shout, and the cyclist is not going to be the one who slows down. Renting a bike for a day is less a novelty activity here than the actual normal way to see the canal ring the way residents do.

The canals themselves date to the 17th century, built during the Dutch Golden Age as the city expanded outward in concentric rings — Prinsengracht, Keizersgracht, Herengracht, roughly translating to Prince's, Emperor's, and Gentlemen's canals. The whole ring is a UNESCO World Heritage site now, and it's genuinely one of the few places where the postcard view and the everyday experience of walking around are the same thing.

Anne Frank House deserves a specific warning: tickets release exactly six weeks in advance and sell out within days, sometimes hours, particularly for summer dates. This is the one booking in Amsterdam that cannot wait until you land — if it matters to your trip, set a reminder for six weeks out and book the moment the window opens.

One distinction trips up a lot of visitors: a "coffeeshop" in Amsterdam sells cannabis, not coffee, and typically doesn't serve alcohol or much of a food menu. A regular café or "koffiehuis" is what most people mean when they picture grabbing a coffee. The signage is different enough once you know to look for it, but the naming overlap catches people off guard on day one.

The Red Light District is centuries old, not a modern tourist construction, and it's worth understanding rather than just gawking at — but photographing the sex workers visible in the windows is illegal and enforced, and treating the area as a nightlife spectacle rather than a real neighborhood with real history tends to land badly with locals. A daytime walk with some context is a better approach than a rowdy night one.
