🇩🇰 Kastrup Sea Bath

Jørn Utzon's masterpiece-level bathing pavilion in Kastrup — a sinuous white ring of bleached oak hovering above the sea. No sauna here, just the Baltic in all its icy glory: a ramped walk down into the water at whatever temperature the season dictates. Breathtakingly beautiful architecture. Free, open year-round, and an essential Copenhagen experience.
