Oslo has a great location at the head of the Oslo Fjord, surrounded by forested hills. The city is a great destination for those who enjoy outdoor activities. Even in the city centre, the nearest park is never more than a few blocks away. A ten-minute boat ride from the centre takes you to lovely beaches on the Oslo Fjord islands. In the winter Oslo has hundreds of kilometers of cross-country trails within the city boundries, in addition to eight ski centres.
