Oslo is so beautiful! Still, a rather expensive city to visit, explore and fully enjoy. But, thankfully, magical fjords sightseeing, delicious Norwegian food and art museums can all come with a discount when using Oslo Pass.
Considering that on Mondays most museums are closed, we used the Oslo pass at the beginning of our trip. More specifically, from Friday to Sunday. And kept a bunch of free things to do and see in Oslo (without a pass) for a Monday morning.
