Oslo Day Trips: 5 Days on a Budget
Five days is the 4-day plan plus one deliberate splurge: a guided Oslofjord sightseeing cruise, the priciest single ticket in this whole family, added on purpose rather than skipped. Still no rental car needed for any of the five days. Want more? The 6-day plan adds Lillehammer’s Olympic sites. See all six versions in the Oslo day trips guide .

Day 1: Land and take one cheap bite of the fjord
Land at Oslo Gardermoen (OSL) and take Flytoget (19-20 minutes, roughly NOK 268) or the cheaper Vy regional train (23-30 minutes, around NOK 124) into Oslo S. Drop your bags in Sentrum or Grünerløkka and load a Zone 1 ticket into the RuterBillett app, NOK 46 for a single fare, it covers the T-bane, trams, buses, and the Oslofjord passenger ferries for the rest of the trip. In the afternoon, walk to the Opera House and climb its free roof for the first proper look at the fjord you’ll cruise properly on day five. In the evening, take the standard Zone 1 ferry out to Hovedøya, the closest island, for a short walk among its ruins and beaches before the light fades. Back in Sentrum for dinner.
Day 2: Fredrikstad’s Gamlebyen, the best value day trip from Oslo
Trains from Oslo S run roughly hourly and take about an hour, with one-way fares clustering around NOK 200-390 depending on how far ahead you book. Don’t stop at the modern Fredrikstad train station and assume you’ve seen the sight; the actual draw, Gamlebyen, sits across the river. Walk to the ferry terminal and take the 2-minute crossing into the walled old town, built in 1567 and still home to roughly 350 residents behind its own ramparts, alongside the cafes, galleries and craft shops lining its streets. Details on the fortress and current hours are on Visit Fredrikstad & Hvaler . Train back to Oslo S for dinner in Sentrum.
Day 3: Nordmarka and Holmenkollen, the day trip your city ticket already covers
Line 1 of the T-bane runs straight to Holmenkollen and Frognerseteren stations, 30 to 40 minutes from Sentrum, on the same Zone 1 fare you loaded on day one. Climb the Holmenkollen ski jump tower and museum, roughly NOK 160-190 for the tower and exhibits, if you want the view and the history. Then walk into Nordmarka itself: in winter, the forest holds roughly 2,600km of groomed cross-country trails, including floodlit sections for after-dark skiing; in warmer months the same trails work as hiking routes past lakes like Sognsvann. T-bane back to Sentrum for dinner.
Day 4: Drammen, the cheapest regional fare on this list
A 30 to 40-minute regional train west of Oslo puts you in Drammen for roughly NOK 125-260 one-way, the least expensive of the three regional-train trips in this plan. It’s a genuine, working Norwegian city rather than a curated tourist stop, so walk the riverside promenade along the Drammenselva and treat the rest of the day as a slow, low-key half-day. Train back to Oslo S for dinner.
Day 5: The Oslofjord cruise, the one genuine splurge
Board a paid Oslofjord sightseeing cruise from Aker Brygge or Langkaia near the Opera House. Most run 50 minutes to 4 hours, and the first departure of the day typically starts around NOK 410, climbing with length and season, roughly nine times the ferry fare you paid on day one for a different stretch of the same fjord. What the extra money buys is commentary and a proper route past Akershus Fortress, not just water. Longer sailings add a stop on an outer island or a dinner service; shorter ones loop back to the harbor by mid-afternoon, leaving time to walk Tjuvholmen’s sculpture park before a final Aker Brygge dinner.
Is Five Days Enough to Justify the Oslofjord Cruise’s Price?
Yes, if you’ve already done the free ferry earlier in the trip and want a longer, narrated look at the fjord as a deliberate treat rather than the only way to see it. Skip day five and keep the NOK 410-plus entirely if the free ferry from day one already scratched the itch; add it back only when a longer sailing or a proper route past Akershus genuinely appeals.
How Much Does This 5-Day Version Cost in Total?
Figure roughly NOK 1,700-2,900 for the five day trips combined, per person: NOK 46 for the ferry, NOK 200-390 for Fredrikstad, Nordmarka on transit already paid for, NOK 125-260 for Drammen, and NOK 410-plus for the cruise itself, by far the single biggest line item in the whole family.
Book the cruise a day ahead rather than walking up; weekend afternoon sailings fill first, and the shorter open-deck routes are the first to cancel in rough weather.
