Central OsloCentral Oslo is small enough that the entire area can be traversed on foot. King Harald V lives in Det Kongelige Slott (Palace), but 15 rooms are open for tourists to visit. The palace is surrounded by a public park. Akershus Slott has both dungeons and ballrooms on view. The Mini Bottle Gallery on Kirkegata shows off an enormous collection of booze from a wealthy brewer.
ToyenToyen is northeast of both central Oslo and the main train station and is situated within walking distance of most major tourist sites. To its south sits Oslo University's botanical garden. The Munch art museum is east of the garden on Ringgata. The Slottsparken is a mile from the botanical garden's southernmost point and a half mile from the postal museum.
The tourist attractions of Bygdoy are easily accessible by ferries leaving from Pipervika.
Uranienborg-MajorstuenWhen it comes to parks in Oslo, Uranienborg-Majorstuen is the place to be. Sandwiched between Vigelandsparken to the west and the Palace Park to the east, here tourists are easily poised to see both the city's palace and the human sculptures on display near Frognar Stadium.
Several consulates are in the neighborhood and most tourist sights in central Oslo are within easy walking distance from here.
