5 Days: Oslo and Norway Day Trips

July 20, 2026

Five days takes the 4-day plan above and adds a full day in Nordmarka, the forest behind Holmenkollen that doubles as Oslo’s easiest ski trip in winter. Going longer? See the 6-day or 7-day version, or the full Oslo day trips guide .

Day 1: Land and Take One Real Bite of the Fjord

Morning

Land at Oslo Gardermoen (OSL) and take Flytoget (19-20 minutes, roughly NOK 240-270) or the cheaper Vy regional train (23-30 minutes, around NOK 124) into Oslo S. Drop your bags in Sentrum or Grunerlokka and load a Zone 1 ticket into the RuterBillett app, about NOK 46 for a single fare, it covers the T-bane, trams, buses, and the public ferries you’ll use for the rest of the trip.

Afternoon

Walk to the Opera House, the white marble roof is free to climb any time and gives you the first real look at the fjord you’re about to spend day two on. Cross to Aker Brygge for a look at tomorrow’s cruise dock.

Evening

Take the standard Zone 1 ferry out to Hovedoya, the closest Oslofjord island, for a short walk among its ruins and beaches before the light fades. Back in Sentrum for dinner.

Day 2: The Oslofjord Sightseeing Cruise

Morning

Board a paid Oslofjord sightseeing cruise from Aker Brygge or Langkaia near the Opera House, most run 2 to 4 hours and cost roughly $35-90 depending on length and operator, with commentary and a route past Akershus Fortress that the free DIY ferry doesn’t give you.

Afternoon

Longer cruises add a stop on one of the outer islands; shorter ones loop back to the harbor by mid-afternoon, leaving time to walk Tjuvholmen’s sculpture park before dinner.

Evening

Dinner at Aker Brygge or Tjuvholmen.

Day 3: Fredrikstad’s Gamlebyen Fortress Town

Morning

Trains from Oslo S run roughly hourly and take about 56 to 65 minutes, with fares typically clustering around NOK 290-390 depending on how far ahead you book. Don’t stop at the modern Fredrikstad train station itself, the actual sight sits across the river, walk to the ferry terminal and take the 2-minute crossing into Gamlebyen.

Afternoon

Walk the ramparts of the walled old town, built in 1567 and still home to roughly 350 residents, then browse the cafes, galleries, and craft shops lining its streets. Details on the fortress and current hours are on Visit Fredrikstad & Hvaler .

Evening

Train back to Oslo S, dinner in Sentrum.

Day 4: Drammen

Morning

A 30 to 40-minute regional train west of Oslo puts you in Drammen, a genuine working Norwegian city rather than a curated tourist stop. Walk the riverside promenade along the Drammenselva.

Afternoon

Treat it as a slower, low-key half-day: a museum stop or a long riverside walk is enough. There’s no must-book attraction here, and that’s the point after three busier days.

Evening

Train back to Oslo S for dinner.

Day 5: Holmenkollen and the Nordmarka Forest

Morning

T-bane line 1 runs straight to Holmenkollen and Frognerseteren stations, 30 to 40 minutes from Sentrum. Climb the Holmenkollen ski jump tower and museum, roughly NOK 160-190 for the tower and exhibits, details at Holmenkollen .

Afternoon

Walk into Nordmarka itself, the forest holds roughly 2,600km of groomed cross-country trails in winter, including floodlit sections for after-dark skiing. In warmer months, the same trails work as hiking routes past lakes like Sognsvann. Tryvann, 18 alpine runs about 25 minutes further by T-bane, covers downhill skiing in winter.

Evening

T-bane back to Sentrum for a final dinner before the longer trips ahead in a 6 or 7-day version.

Can You Ski at Holmenkollen on a Single Day Trip From Oslo?

Yes, and it’s the simplest ski trip in Scandinavia to fit around a city base. The T-bane puts you at the trailhead in well under an hour from Sentrum, rental gear is available near the station, and the groomed Nordmarka network is large enough that a single afternoon barely scratches it.

Transportation

Flytoget or Vy from Gardermoen, see Day 1 for the fare difference
Ruter covers the T-bane, trams, buses, and the Oslofjord passenger ferries on one ticket, and reaches Holmenkollen directly
Regional trains to Fredrikstad and Drammen both run on Vy, book a day ahead for the best fare

Tips

Norway runs on the krone (NOK), not the euro, Schengen and EEA territory but not EU
Neither the Oslo Pass nor a standard Ruter ticket covers the Fredrikstad or Drammen trains, though Ruter does reach Holmenkollen and Nordmarka
Pack real footwear for Nordmarka even outside ski season, the forest trails get muddy fast after rain

Rent ski gear near Holmenkollen station rather than hauling your own, most shops there are used to fitting day visitors in under 15 minutes.
