4 Days in Copenhagen: The Gateway Itinerary

Four days runs the same Malmo-Roskilde-Kronborg spine as the 3-day version and adds Denmark’s grandest Renaissance palace on day four. Base near Central Station, all four trips leave from the same platform. Tighter schedule? Drop to 2 or 3 days . More time? Step up to 5 , 6 , or 7 days .

Day 1: Base Yourself, Then Cross Into Sweden

  • Check into a hotel within walking distance of Copenhagen Central Station, every trip on this itinerary departs from the same platform
  • Buy tickets via the Rejsebillet app or tap a contactless card at the gate, the plastic Rejsekort is retired for good on 28 May 2026
  • Catch an Oresundstag train to Malmo Central, 35-41 minutes, fares from around 150 SEK (roughly 110 DKK/€14/$15), carry ID for the random Oresund border checks
  • Walk Malmo’s Old Town (Gamla Staden) and Lilla Torg, compact enough for a couple of hours, and remember it’s Swedish kronor here, not Danish kroner
  • Train back to Copenhagen by mid-afternoon, a relaxed dinner near your hotel closes the day

Day 2: Roskilde, Viking Ships And A Royal Cathedral

  • Regional train to Roskilde, 25-27 minutes, fares from about 84 DKK, over 100 departures a day
  • Viking Ship Museum , 160 DKK adult, five actual excavated Viking-age vessels, plus a 120 DKK sailing add-on May-September
  • Walk or ride bus 203 the 1.5km/20 minutes to Roskilde Cathedral , 80 DKK as of July 2026, the Danish royal burial church holding 20-plus monarchs across 800-plus years
  • Best single day trip on this whole list, give it the full day

Day 3: Kronborg Castle, Hamlet’s Castle At Helsingor

  • Kystbanen coastal train, every 20 minutes, about 46 minutes, fares from around 78 DKK
  • 10-minute walk along the harbor to Kronborg Castle , entry roughly 135-150 DKK depending on season
  • No evidence Shakespeare ever visited Denmark, “Hamlet’s castle” is a literary legend on a genuinely stunning 16th-century UNESCO fortress, go for the castle, treat the Hamlet tag as the hook
  • Train back to Copenhagen in the late afternoon

Should I rent a car for these day trips? No. Every trip on this itinerary, Malmo, Roskilde, Kronborg, and Frederiksborg, runs on frequent direct trains from Copenhagen Central, and Danish train stations sit closer to each town’s actual sights than any parking lot would. A car adds cost and complexity for zero benefit here.

Day 4: Frederiksborg Castle, Denmark’s Grandest Renaissance Palace

  • S-train Line A from Copenhagen Central, 35-40 minutes, frequent departures every 10-20 minutes
  • 15-minute walk from Hillerod station to Frederiksborg Castle , entry roughly 125 DKK, home to the Museum of National History across Denmark’s grandest Renaissance palace and gardens
  • This is deliberately a solo-focus day, Frederiksborg and the Louisiana Museum sit on opposite train lines from Copenhagen and I wouldn’t combine them, each earns its own unhurried 2-3 hours
  • Train back to Copenhagen in the early evening for a final dinner near your hotel

Things worth knowing for this route

None of these four trips need an advance ticket, buy your train fare and entry same-day. Pack a downloaded train schedule for whichever route you’re doing, Danish trains run frequently but a missed connection can still cost real time.
