The Oslofjord, the Islands and Oslo's Maritime Life
The Oslofjord, stretching 100 kilometres from the city to the open sea, is Oslo's primary natural amenity and the source of a maritime culture that shapes the city's social life throughout the warmer months. The Oslomarka forest, which begins at the end of the city's tram lines and extends over 1,700 square kilometres, provides a counterpoint: hiking, skiing, and lakeside swimming within 30 minutes of the city center. The inner fjord islands — Hovedøya, Langøyene, Gressholmen, and others — are accessible by public ferry from the Aker Brygge and Rådhusbryggen piers throughout summer, providing free beaches and picnic areas used by Oslo residents as an extension of their own back garden. Langøyene has the most popular free beach in the fjord, while Hovedøya offers the ruins of a 12th-century Cistercian monastery on its wooded paths. The Viking Ship Museum on Bygdøy peninsula, home to three Viking Age burial ships including the Oseberg ship dated to 834 AD and the best-preserved Viking vessels in existence, is the most visited museum in Norway and documents a seafaring culture whose reach extended from North America to the Byzantine empire. The Fram Museum, housing the polar exploration vessel Fram — the ship that sailed further north and further south than any other wooden vessel in history — occupies a purpose-built hall on Bygdøy and presents the history of Norwegian polar exploration with an immediacy that few maritime museums can match.
