Frederiksborg Castle is included on the Discover card, not Hop. Adult entry is €17 (125 DKK) without one. It opens every day of the year, including Mondays.
The Discover card covers the castle and the train to Hillerød. The castle's own site states card holders pay 0 DKK with no need to book.
Christian IV's castle on three islets in a lake, rebuilt after fire by the Carlsberg brewer and reopened as the national portrait collection. Allow two to three hours.
One of the few interiors that survived the 1859 fire — the coronation church of Danish absolute monarchs, with the original organ from 1610 still in place and still played.
The full length of the upper floor, with a carved and gilded ceiling and tapestries below it. Rebuilt after the fire from the original drawings rather than reimagined.
Terraces stepping down to the lake with the castle reflected in it, restored to the 1720s layout. Free to walk, and the view back at the castle is the one the building was designed for.
Two things make this the easiest of the big day trips on the card. Both confirmed against frederiksborg.dk.
Hillerød is about 40 minutes north of Copenhagen on the S-train, then a short bus. The Discover card covers the whole journey; the Hop card covers none of it.
It covers Frederiksborg Castle along with 80+ other attractions and all public transport.
No one sells Frederiksborg entry on its own. This is a full-day minibus tour that also takes in Kronborg, Roskilde Cathedral and the Viking Ship Museum, with a guide and hotel pickup. The card covers all four — €67 at the doors — and the trains there, for less. You are paying for the guide and the driving. The tour gives Frederiksborg about two hours, which visitors say is not long for a castle this size.
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.
The house at Rungsted where Karen Blixen grew up, returned to and wrote, kept as she left it, with a bird sanctuary in the grounds and her grave under a beech tree.
Rudolph Tegner's own museum and statue park set in open heathland at Dronningmølle — a concrete rotunda surrounded by bronzes in a field.
Hamlet's Elsinore, guarding the narrowest point of the Øresund, with casemates below and a 62-metre ballroom above. A UNESCO World Heritage Site.
Entry is €17 per adult (125 DKK) and the return train is about €8 — €25 for one day out. The Discover card covers both, along with 80+ more attractions and unlimited public transport.
Entry is free on the Copenhagen Card Discover, and the castle's own site states card holders pay 0 DKK with no advance booking. The ticket is valid all day and covers every special exhibition. The Hop card does not include it. Adult entry is €17 (125 DKK) without a card.
Frederiksborg opens every day of the year, Mondays included, which makes it one of the few dependable Monday options alongside Copenhagen Zoo, Experimentarium and the Viking Ship Museum. Rosenborg, by contrast, closes on Mondays through the winter.
Nothing needs booking at all — the castle states card holders pay 0 DKK with no need to book in advance. Show the QR code in the Copenhagen Card app at the desk and walk in. This is the simplest entry of any card attraction.
One scan per attraction applies, so Frederiksborg is a single visit per card. The ticket is valid for the whole day though, so going out to the Baroque Garden and coming back in is fine — that is one visit, not two.
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.
