For fresh water swimming, Akerselva is considered clean north of Nydalen. The best spot may be at Frysja (bus 22-25-54 to Stillatorget). Don't forget that many of the lakes in "Oslomarka" are for swimming and recreation (Sognsvann lake for instance). Note that some major lakes (Maridalsvannet in particular) are drinking water for the city, restrictions on swimming and camping. Buy a map and bring your swimming gear!
Sognsvann lake is one of the most popular places in Marka (Oslo forest), nice meadows and easy path around lake, paths continue through the forest - metro line 5 to Sognsvann station. Surprisingly this lake is the geographical mid point of Oslo.
Marka
Oslo is surrounded by wide and partly dense forests, generally known as Marka, of which Nordmarka is the largest and most accessible section (in addition to Nordmarka there similar areas east, south and west of the city). There are lots of roads and trails criss-crossing these wide forests, but no cars, only skiers, hikers and bicycles. So it is essentially the largest park in town. There are countless lakes, many rivers and small waterfalls too. Small summits that rise above the city offers excellent panoramas. Entry points everywhere, usually 10-15 min from the centre. Access by bus, metro, tram, car or bicycle. There is a fine network of high quality foot paths (roads) suitable even for wheelchairs and baby strollers, as well as many "nature trails" for hikers and skiers only. Roads closest to the city have street lights. In winter used for cross-country skiing, also a small ski resort (alpine skiing). The Moose (elg), mainland Norway's largest animal, roam the forest and occasionally strolls into town. Note: the Oslo forest is drinking water supply for 1 million people. Restrictions on camping, barbecue and swimming.
Among Oslos best hidden secrets. Gustav Vigeland's not so well-known younger brother erected the building as a museum for his art in 1926, but later decided it should serve as a mausoleum, with his urn placed above the door. The main attraction in this museum with no windows is the 800 square meters fresco "Vita", (Italian for "life"), showing the human life from conception till death, but other examples of his art are also on display. Included in the Oslo Pass.
