Take a stroll along Aker Brygge, a waterfront area known for its lively atmosphere and array of shops and restaurants.
Begin the day with a visit to the Viking Ship Museum, where you can see Viking ships and artifacts up close. Continue to the Fram Museum and explore the world's first polar ship. Then head to the Vigeland Sculpture Park to see more than 200 bronze, granite, and cast iron sculptures. The park is perfect for a picnic or a peaceful walk.
Start with the Oslo Opera House, a stunning piece of architecture with a massive roof that doubles as a public space. Next, head to the Munch Museum to view works by Edvard Munch, Norway's most famous artist. End the day with a visit to Mathallen, a food market with an array of culinary delights from around the world.
If you have more time, consider taking a ferry to one of the nearby islands like Hovedøya or Gressholmen for a scenic hike. For those with less time, consider skipping the Munch Museum or Mathallen. Don't forget to try some traditional Norwegian food like smørbrød (open-faced sandwiches) or fårikål (lamb and cabbage stew).
