Every day at noon, the Royal Guard marches from Rosenborg Castle to Amalienborg Palace, and when the monarch is in residence, the band plays too.

Several companies run pay-what-you-wish walking tours of the historic centre, technically free, tip what you think it was worth. Even more unusual: GreenKayak, a non-profit with stations at Svanemøllehavnen and Arsenalvej, lends out two-person kayaks completely free for two hours in exchange for collecting floating rubbish from the canals, life jackets, paddles and a trash grabber included. It's a genuinely different way to see the harbour, and it comes with a good conscience attached.

Tip: Book GreenKayak slots via their app, they go fast on sunny weekends. For a guided, paid alternative with deeper storytelling, see my private walking tour.
