Enjoying Fresh Shrimp off the Boats -- In the morning, head for the harbor in front of the Rådhuset and buy a bag of freshly caught and cooked shrimp from a fisherman. Although this may not be everyone's idea of a good breakfast -- sales begin around 7 or 8am and may end in late morning -- shrimp fans will love it.

Experiencing Life on the Fjords -- In the summer, head for the harbor, where boats wait to take you sightseeing, fishing, or to the beach.

Hanging Out in the Students' Grove -- Summer is short in Oslo, and it's savored. Late-night drinkers sit in open-air beer gardens, enjoying the endless nights.

Listening to Street Musicians -- Hundreds of musicians flock to Oslo in the summer. You can enjoy their music along Karl Johans Gate and at the marketplace Stortorget.

Taking the Ferry to Bygdøy -- The Bygdøy peninsula offers a treasure trove of attractions including Viking ships, Thor Heyerdahl's Kon-Tiki, seafood buffets, a sailboat harbor, and bathing beaches. At the folk museum are old farmsteads, houses, and, often, folk dancing.
