Copenhagen is packed full of beautiful buildings. Watch the changing of the guard (11.30am) at Amalienborg Palace – the winter home of the Danish royal family. From here, take a walk along the waterfront to the star-shaped Kastellet, one of the best-preserved fortresses in Northern Europe, with picturesque berry red barracks and cobbled streets. Close to here is the underwhelming but must-see Little Mermaid statue of Hans Christian Andersen’s most famous character. Walk thorough neighbouring Østre Anlæg Park to the fairytale Rosenborg Castle with its green turrets and symmetrical gardens. Finally, head down Gothersgade street to Nyhaven and spend the evening in Copenhagen’s most famous spot. Pitch up like the locals, legs dangling above the canal, can of beer in one hand, hotdog in the other, and gaze at the reflection of the multi-coloured houses in the water.
