This summer, I went to Oslo for a few days. The occasion was, that a friend of mine was doing Interrail through Europe, and as I am always looking for excuses to book a trip, this was perfect. I went for three nights and like that, I had two full days to explore the city. I flew from Zurich, Switzerland, to Oslo, Norway; you can read all about the flight here.
When I arrived at the airport in Oslo, I took the special airport train called “FlyToGet”, which takes you almost directly to the central main station in the middle of the city. It's super convenient and less expensive than a taxi.
On the third day, we decided to take the train out of the city to “Holmenkollen” a ski jump and museum. It’s not that I’m a fan of ski jumping or winter sport in general, but this was impressive anyway and the view from the top of the ski jump was great. In the afternoon, we went for a fjord cruise on a hybrid catamaran. While most happy being under the water, on the water is also “just fine”. The fact that the boat drove completely electric made it super peaceful without any motor sounds and smells.
After two fully packed days of exploring a new city, on Saturday it was already time to leave. While those days were great, I can also say, that you don’t need more time to explore Oslo. Three nights is perfect, I think if you want to do it in two, it’s also possible.
To sum it up here, is it worth it? Sure, traveling and exploring is rarely not worth it, but Oslo is the wrong country, if you expect it to be extremely different in nature and/or culture compared to Switzerland. Sure, there are a few small differences, but overall, there is nothing such as a culture shock. Would I go again? Probably not again Oslo, because “been there, done that”, but I would explore other northern cities or plan an extended Scandinavia trip, which includes not only cities.
