Oslo Day Trips: 3 Day Itinerary (No Traps)

Three days is enough for the two best day trips out of Oslo plus a third that costs nothing beyond a metro ticket: the Oslofjord ferry on day one, Fredrikstad’s fortress town on day two, and the Nordmarka forest on day three. Only have 2 days? Drop day three and see the 2-day version . Got a 4th day? The 4-day plan adds Drammen, the one on this list that’s genuinely optional.

Book these before you go

Day 1: Land, settle in, and take the cheap ferry

Base yourself in Sentrum or Grünerløkka, both covered in visitoslo.com’s neighborhood guides and within walking distance of Oslo S and the ferry terminals at Aker Brygge. Buy a standard Ruter ticket, NOK 46, and take the public ferry out to Hovedøya, about 12 minutes across the water, for Cistercian monastery ruins and rocky swimming spots. Bring food from a Rema 1000 or Kiwi rather than relying on the island’s limited cafe, and be back in the city for an easy first evening in Grünerløkka.

Day 2: Fredrikstad’s walled old town

The Vy train from Oslo S to Fredrikstad runs just under an hour, close to hourly and every 30 minutes at rush hour. Gamlebyen, the walled old town across the river from the modern station, is the largest and best-preserved fortress town left in northern Europe, still lived in behind its 1567 ramparts; visitfredrikstadhvaler.com covers the exact connection, a short walk plus a 2-minute ferry crossing gets you inside. Budget the whole day between transit and the town itself.

Day 3: Nordmarka and Holmenkollen, free on the metro

T-bane Line 1 reaches Holmenkollen station in about 25 minutes on the same standard ticket, no extra fare. Climb to the ski jump tower and museum (roughly NOK 160-190, verify current pricing) for a fjord view that rivals anything you’d pay for elsewhere in the city, then walk into Nordmarka itself, a groomed trail network running to roughly 2,600 kilometres. If the weather and season allow it, Sognsvann lake at the end of T-bane Line 5 is the classic free summer swim spot to finish the day.

Which day trip should you cut if the weather turns?

Nordmarka. Fredrikstad’s old town and the Oslofjord ferry both hold up fine in light rain, since most of what you’re doing is walking through a historic town or riding a covered ferry, but Nordmarka’s appeal is largely the forest itself and a swim, neither of which improves in a downpour. Swap it for a museum day in the city instead.

Can you do the Oslofjord ferry and Fredrikstad on the same day?

Technically, but don’t. The ferry alone with any time on Hovedøya takes a half day, and Fredrikstad needs the better part of a full day once you count the hour each way on the train. Combining them means rushing both; spreading them across two separate days, as this plan does, gets you more out of each.

Day trip From Oslo Travel time Typical cost
Oslofjord islands (ferry) Aker Brygge / Vippetangen 12-15 min each way NOK 46, standard Ruter ticket
Fredrikstad (Gamlebyen) Oslo S by Vy train about 1 hour each way Verify current one-way fare on vy.no
Nordmarka / Holmenkollen Oslo S by T-bane Line 1 about 25 min each way Standard Ruter ticket, no extra fare

Pack real shoes for day three. Nordmarka’s trails are genuine forest paths, not paved city walkways, and the ski jump viewpoint involves a short uphill walk from the station that isn’t kind to sandals.
