Oslo is made for walking - in fact, you can walk from the Central Station all the way to the Royal Palace in a straight line.
Except for excursions to the museum-loaded Bygdøy peninsula and the Holmenkollen Ski Jump, most attractions can be covered on foot. Oslo is not neatly divided into separate neighborhoods or districts.
It consists mainly of central Oslo, with the Central Station to the east of the city center and the Royal Palace to the west. Karl Johans Gate, the principal street, connects these two points.
