Oslofjord vs Geirangerfjord: An Honest Comparison

Geirangerfjord sits about 450 kilometres from Oslo by road, close to seven hours of driving before you stop for anything. The Oslofjord starts nineteen minutes from the airport, at the bottom of the city. Past the word "fjord" the two have very little in common, and choosing between them is mostly a question of how many days you have.

Geiranger is the postcard: 15 kilometres of glacier-cut water under mountain walls of 1400 to 1700 metres, on the UNESCO list since 2005 (Store norske leksikon on Geirangerfjorden). The Oslofjord is a hundred kilometres of drowned fault line with a working capital at the head of it. With a week in Norway you can have both. A long weekend in Oslo leaves one of them reachable.

How each one was made

Geirangerfjord is a fjord by the textbook: a narrow inlet cut by glaciers, running 15 kilometres in from Hellesylt, between 500 and 1500 metres wide, 258 metres deep at the deepest point, ending at the village of Geiranger.

The Oslofjord was made twice over. The crust dropped along fault lines in a rift zone that opened in the Permian, and the ice ages later dug the basin out (Store norske leksikon on Oslofjorden). That is why it is broad where Geiranger is tight: 3 to 5 kilometres across in the inner fjord behind the kilometre-wide narrows at Drøbak, and 10 to 20 kilometres across further out, with islands scattered through it. What is the Oslofjord takes the geology further.

Getting there

From Oslo Airport, the airport express train reaches the city centre in 19 minutes, and our boats leave from Tjuvholmen a short walk on from there. Geiranger is roughly 450 kilometres away: close to seven hours behind the wheel, or a flight to Ålesund and then about 110 kilometres of road, which takes a good two hours. For most visitors flying into Oslo, Geiranger is a two-day commitment before it is worth doing at all.

It is seasonal too. The mountain road over Trollstigen is closed from October to May, and Hurtigruten calls at Geiranger from May to September (Store norske leksikon on Geiranger). The Oslofjord itself is open all year, though our own boat comes out of the water in October and goes back in for the spring. Winter on the fjord is met from the shoreline.

What you actually look at

Geirangerfjord is vertical. Cliffs close in on both sides, the Seven Sisters comes off the top of one of them, and the abandoned mountain farms sit on ledges that look unreachable: Skageflå is 270 metres above the water. The car ferry between Hellesylt and Geiranger sails several times a day and takes a little over an hour each way, which is the standard way to see the fjord.

The Oslofjord is horizontal, and most of what you look at is inhabited. You pass the Opera House at sea level, then Akershus Fortress, begun by Håkon V around 1300 (Store norske leksikon on Akershus), then the Munch museum at Bjørvika and the galleries on Tjuvholmen, and after twenty minutes you are out among the islands. Hovedøya has the ruins of a Cistercian monastery founded in 1147 (lokalhistoriewiki on Hovedøya). Gressholmen held Oslo's first airport: Oslo Flyvehavn, established in 1926, inaugurated on 16 July 1927, overtaken by Fornebu in 1939, with the last plane leaving the hangar in 1952 (lokalhistoriewiki on Gressholmen). Lindøya is covered in painted wooden cabins that people still summer in. The islands of the Oslofjord has the rest of them.

White-tailed eagles are back on this fjord as well. A chick fledged on Håøya in the Drøbak narrows in the summer of 2008, the first successful breeding by the Oslofjord in 126 years (BirdLife Norge). What else is out there depends on the month, and the seasonal wildlife guide goes through it.

Crowds

Around 800,000 tourists come to Geiranger in a year, more than 40 per cent of them by sea. In 2018 that meant 188 cruise ships and close to 250,000 cruise passengers; 178 ships called in 2022. The village itself has 215 residents (Store norske leksikon on Geiranger, 2023 figure). From 1 January 2026, passenger ships under 10,000 gross tonnes in the World Heritage fjords have to run on energy sources that emit no CO2 or methane, with ships of 10,000 tonnes and above following on 1 January 2032 (forskrift om miljømessig sikkerhet for skip, § 10b).

Oslo carries more visitors and shows it less. The county recorded 6.9 million overnight stays in 2025, the highest of any county in Norway (SSB), and they spread out across a city and a hundred kilometres of water. Cruise ships dock at Søndre Akershuskai and Vippetangen, the island boats run from the City Hall piers, and a boat with seven people on it vanishes into that. We can still find an empty bay in mid-July.

Which one fits your trip

Two or three nights in Oslo, and it is the Oslofjord. No Geiranger round trip fits inside that window. The three-hour private cruise from Tjuvholmen costs NOK 16,688 for the whole boat and covers the inner fjord, the islands, the historic harbourfront and a swim stop.

A week or more, and you want the image everyone recognises: go to Geiranger, most easily as part of the Bergen, Flåm and Nærøyfjord loop. Most people who do that loop put Oslo at one end of it, which is where the Oslofjord fits, on the day you land or the day before you fly home. Each is worth a day, and a week in Norway has room for both.

Guests sometimes apologise for asking us about Geiranger. They should not. We tell them to go, and then to come back and take an evening cruise here. You live on the Oslofjord for a few days. You travel to Geiranger to look at it. They are not the same trip.

The other west-coast fjords

Geiranger is not the only candidate for the trip west. Sognefjorden is the longest in Norway at 205 kilometres and the deepest at 1303 metres (Store norske leksikon on Sognefjorden). Nærøyfjord went onto the UNESCO list in 2005 alongside Geiranger and is narrower than it. Lysefjorden has Preikestolen standing over the water. Hardangerfjord is the orchard one, in blossom in May. If Geiranger does not fit your route, Nærøyfjord out of Flåm is the easiest fjord day from Bergen.

If you only have one day in Oslo

The Ruter island boats leave from the City Hall piers and reach Hovedøya and Gressholmen on an ordinary transit ticket. A single-zone ticket runs out 60 minutes after you activate it, so a round trip with time ashore needs a 24-hour ticket or a second single (current Ruter fares). A three-hour private cruise covers more ground, anchors in bays the scheduled boats do not enter, and includes a swim stop. Either way you get the fjord. Compare tour options.
