4 Best Sights in Frogner and Majorstuen, Oslo

A feat of world-class engineering, this beloved ski jump was first constructed in 1892 and has been rebuilt numerous times, remaining a distinctive part of Oslo's skyline. The cool, futuristic-looking jump you see today still hosts international competitions. The ski-jump simulator puts you in the skis of real jumpers, and the world's oldest ski museum presents 4,000 years of ski history. Guided tours of the museum are available.

A favorite hangout for locals, Vigeland Sculpture Park has 212 bronze, granite, and wrought-iron sculptures by Gustav Vigeland (1869–1943). The 56-foot-high granite Monolith is a column of 121 upward-striving nudes surrounded by 36 groups on circular stairs. The Angry Boy, a bronze of an enraged cherubic child stamping his foot, draws legions of visitors and has been filmed, parodied, painted red, and even stolen. Kids love to climb on the statues. There's an on-site museum for those wishing to delve deeper into the artist's work.
