hi there,
Here are some popular sights in Oslo:
- The Akershus Festning is a great place where you can sit for a picnic and observe the Fortress and get perfect views over the Oslo
Fjord.
- The Islands in the Oslo fjord such as Langoyene or Hovedoya islands are two great places to explore and they're only a ferry away from downtown
Oslo.
- The Vigeland's Park is a lovely park to stroll by with the family and observe some of the statues.
Hope this helps
