The Danish Museum of Science and Technology is included on the Discover card, not Hop. Adult entry is €17 (130 DKK) without one. It is in Helsingør, and the train is covered.
The Discover card covers entry and the fifty-minute train each way. The Hop card covers neither.
Denmark's national collection of technology, in hangar-scale halls on the edge of Helsingør. Allow two hours, plus the journey.
Full-size aircraft, including early Danish machines, in a space with the height to show them properly. This is the part that justifies the building being where it is rather than in the city.
The vehicles and machinery that carried Danish industry, laid out at a scale a city-centre museum could not hold. It is a museum about how things worked rather than who owned them.
Fifty minutes each way is a real commitment for one museum. Kronborg is in the same town, on the same card, and the two make a full day that neither justifies alone.
The Monday rule here follows the school calendar rather than the seasons, which makes it the hardest one on the card to predict. Confirmed against tekniskmuseum.dk and the 2026 Copenhagen museums folder.
Helsingør, about fifty minutes north by train. The whole journey is on the Discover card.
All three are included on the same card, so the only cost of adding them is the time. For the full list, see every attraction the Copenhagen Card covers.
Hamlet's castle guarding the narrowest point of the Øresund, with the casemates and Holger the Dane beneath the courtyards.
Denmark's maritime history built into the old dry dock next to the castle, below ground level.
The marine life of the Øresund, at the university research station on the coast.
Entry is €17 per adult (130 DKK) without a card, and the train to Helsingør is covered too. The Discover card includes both, along with 80+ more attractions.
Entry is free on the Copenhagen Card Discover, which also covers the 50-minute train to Helsingør. Adult admission without a card is €17 (130 DKK) and under-18s are free. The Hop card does not include it — Helsingør is a day trip.
Monday opening follows the Danish school holidays rather than the calendar: the museum closes Mondays for most of the year but opens on them during school holiday periods. Check tekniskmuseum.dk before a Monday trip, since a date alone will not tell you.
Nothing needs booking. Show the QR code in the Copenhagen Card app at the desk and walk in. The train to Helsingør is covered on the same card, so nothing needs buying at either end.
One scan per attraction applies, so this is a single visit per card. At fifty minutes each way, most people pair it with Kronborg in the same town rather than making two trips to Helsingør.
Show the live QR code in the Copenhagen Card app at the entrance and let staff scan it. Your booking confirmation email is not your card, and a screenshot of the QR code will not scan — it has to be the app itself, which works offline once activated.
