Oslo is the capital and largest city of Norway, and the third largest city of Scandinavia. Although well into the northern latitudes, Oslo’s climate is fairly temperate thanks to warm air being wafted across the Atlantic from the Gulf Stream. Summer weather in Oslo is mild and pleasant, with frequent hot spells, and plenty of long sunny days. In winter temperatures hover just above or below freezing. Snow is most often plentiful in the forested areas and also often in the city in winter, making it a great winter sports venue.
There are plenty of things to visit, like The Royal Palace, Opera House, Oslo Cathedral, Kirkeristen (the old bazaar surrounding the church is now used by artisans and craftsmen, and holds a couple of cafes and restaurants), Akershus Festning (a medieval castle and fortress built in 1299, located close to the city center) and many more. Oslo also has amazing museums. If you are planning on seeing several of the expensive attractions in a short period of time, then the most cost effective way to do this is to buy an Oslo Pass. It includes unlimited entry to most of the museums. Some of the most notable museums are Henrik Ibsen Museum, Munch Museum, National Gallery, Nobel Peace Centre and Emanuel Vigeland Museum. There are also some nice parks that you should definitely visit, like Frogner Park, Slottsparken and Sofienbergparken.
