Oslo is tucked in between the hills and the sea and during the summer the locals gravitate down towards the water, where they can sunbathe, eat, drink and generally be beautiful.
If you want to experience the whole span of seaside life in Oslo then the recently opened Oslo Promenade is a winner. It’s a 9km marked path and covers the center of town, from the rich suburbs of Frogner to the formerly industrial docks on the east. There are 14 posts in all, bright orange industrial containers with information on the area and some old photos. I recommend starting west by Frognerkilen and working your way towards downtown where you can stop for some food or a beer before continuing out past the Opera to Vippetangen and Sørenga. The eastern tip takes you a bit into no-man’s land (and up a hill) so most of the time I stop at Sørenga.
I like to cycle the route as there are some long gaps between the posts and it’s nice then to be able to zip along. The whole route is actually covered by the city bike scheme but the max rental time is 45 mins so you might need to deliver the bike back and wait a few minutes before picking up a new one to continue on.
Combining exercise with being social – now you are really a local!
