Is NiN worth it if it is all you are going to do in Norway?

You still have to arrive and depart to Norway via Oslo and/or Bergen, so I hope you'd at least allow a day for each city you transit through. If you have 4 nights not yet written "in ink," what other stops are "in pencil" or under consideration?

Hello Laura! The idea was to fly in Oslo in the morning, spend night there in order to take the early train for NIN. So I am thinking half a day in Oslo doesnt seem like a lot to do. Then arriving in Bergen in the late evening, spending the night there and taking a flight to Billund the next day. Not a lot of time in Oslo or Bergen, so I was wondering if I really want to spend these 3 nights basically to do NiN. Thanks for your help.

I guess I miscalculated. I will one full day for either Oslo or Bergen, which would you suggest?

The other "in pencil" would be to spend those days either just Oslo or just Stockholm.

Oslo is worth two full days, with at least one full rushed day just to enjoy the highlights:

My favorites:

▲▲▲ City Hall Oslo's artsy 20th-century government building, lined with huge, vibrant, municipal-themed murals, best visited with included tour.

▲▲▲ National Gallery Norway's cultural and natural essence, captured on canvas.

▲▲▲ Frogner Park Sprawling park with works by Norway's greatest sculptor, Gustav Vigeland, and the studio where he created them (now a museum).

▲▲▲ Norwegian Folk Museum Norway condensed into 150 historic buildings in a large open-air park.

▲▲ Norwegian Resistance Museum Gripping look at Norway's tumultuous WWII experience.

▲▲ Viking Ship Museum An impressive trio of ninth-century Viking ships, with exhibits on the people who built them.

▲▲ Fram Museum Captivating exhibit on the Arctic exploration ship. (Three diamonds in my opinion).

▲▲ Holmenkollen Ski Jump and Ski Museum Dizzying vista and a schuss through skiing history.

▲ Nobel Peace Center Exhibit celebrating the ideals of the Nobel Peace Prize and the lives of those who have won it.

▲ Akershus Fortress Complex and Tours Historic military base and fortified old center, with guided tours, a ho-hum castle interior, and a couple of museums (including the excellent Norwegian Resistance Museum, listed above).

And Bergen is worth at least a full day:

Day 9: Historic and Artistic Oslo
We'll greet the sun as we glide up the Oslofjord — one of the most scenic parts of our tour — and into Norway's capital. Once ashore, we'll take a walking tour around the harbor and through the heart of Oslo, learning about Norway's history and politics along the way. With your Oslo Pass, you'll have plenty of free time to visit the Norwegian Resistance Museum, or your choice of the city's other fine museums. Before tonight's dinner, we'll gather for a visit to Frogner Park, home to Gustav Vigeland's whimsical, lifelike sculptures. Sleep in Oslo (2 nights). Bus: 1 hour. Walking: moderate.

Day 10: Norway's Seafaring Past
Today we'll cruise across the harbor to Bygdøy peninsula for a treasure trove of nautical history. We'll visit the Viking Ship Museum to learn about Scandinavia's best collection of Viking vessels and artifacts. Nearby, you'll also have time to see the impressive Maritime Museum — as well as special museums devoted to the innovative Fram polar explorer and the ocean-crossing rafts of adventurer Thor Heyerdahl (Kon-Tiki and Ra II). Inspired by Norway's seafaring history, you'll be free to sail back to Oslo's harbor. From there, armed with your Oslo Pass (giving you free admission to most museums and public transportation), you'll have the rest of your afternoon and evening free in this vibrant city. Boat: ½ hour. No bus. Walking: moderate.

My favorite part of the Norway in a Nutshell was the one hour Flam Railroad ride down into the fjords. If you have extra time, spend it in Bergen. The people there are very sweet and absolutely the most beautiful (and tall) I have ever seen.

Thank you for all your excellent suggestions. I am now of the mind to end the NiN tour at Voss and return to Oslo the same day. It seems like the Voss - Bergen part of the trip is not as picturesque as the preceeding legs. This also allows us to keep the room in Oslo and not have to travel with our carry-on bags.

Unless ofcourse, a day in Bergen is better than a day in Oslo :)

I did Norway in a Nutshell two weeks ago.

The train ride from Oslo to Myrdal gets scenic the closer to you get Myrdal. The railway from Myrdal to Flam, ferry from Flam to Gudvangen, and bus from Gudvangen to Voss are very scenic. The train from Voss to Bergen was nice but a let down after the rest of the tour.

While it can be done in one day, I did it in two and spent the night in Flam. I glad I did.

I liked Bergen much more than Oslo. But i liked cruising the fjord most of all.
