The Oslo Winter Park at Tryvann (Norwegian: Oslo Vinterpark) is a ski resort in Oslo, Norway. It is the most used ski resort of Norway. In the 1930s, the ski slope Tryvannskleiva was constructed, and the first race was held in 1933. The ski slope was later expanded with Tommkleiva, Wyllerløypa and finally with Tryvann Ski Resort. As of winter of 2010, the resort has 14 slopes and 7 lifts. There is only 1.2 km (0.75 mi) walking or bus distance from the Voksenkollen metro station.

Tryvann stadion was a speed skating rink located at Tryvannshøyden in Oslo, Norway. Traditionally the main speed skating venues in Oslo was Frogner stadion and Bislett stadion. In 1933, the city council decided to build a skating rink at Tryvann to allow for a longer season. Unlike the city-center venues which were just above mean sea level, Tryvann stadion was located at 517 meters (1,696 ft) above mean sea level. This allowed the skating season to last from 1 November to 1 April. Transport was available via the Holmenkollen Line. During the 1952 Winter Olympics, the venue was designated as a reserve venue for Bislett, but never used. During the 1970s, the venue was demolished to make room for parking.

Øvresetertjern is a lake in Oslo, Norway. It is located 477 metres (1,565 ft) over sea level between the top of the hill Tryvannshøyden and Frognerseteren. From 1916 to 1938, the station Tryvandshøiden was located north of the lake, but it was never served by regular passenger trains.

It is also the second highest station on the network, 460 meters (1,510 ft) above mean sea level. The station was opened on 16 May 1916 when the line was extended from Besserud (then called Holmenkollen) to Frognerseteren.The station is the one closest to the transmitting tower and tourist attraction Tryvannstårnet. Also near the station are a number of hotels and conference centres, including Soria Moria, where the Stoltenberg's Second Cabinet had their preliminary discussions in 2005.

Tryvann is a small lake in Nordmarka, the forest area just north of Oslo city, near the Holmenkollen ski jump. By the water lies a cabin called Tryvannstua, in which there is a café open regularly during both summer and winter. On a hill above the lake looms the television tower Tryvannstårnet ("The Tryvann tower"), visible from most of Oslo. Tryvann is the entry and beginning of Nordmarka. It is used all year around. The key purposes of this area in the winter are skiing and cross-country skiing, whereas in the summer it is more commonly used for walks in the forest and biking. When referring to Tryvann, it is mostly referred to as the Tryvann vinterpark.

Frognerseteren is the end station of the Holmenkollen Line of the Oslo Metro, located in the Marka section of Oslo, the capital city of Norway. It the northernmost station in Oslo Metro, and is the station after Voksenkollen. The line to Frognerseteren was completed on 16 May 1916. The station has two platforms which, like other stations on the Holmenkollen Line, only accommodate two-car trains. The elevation of the station is 469 meters (1,539 ft) above sea level, the highest of all the stations in Oslo. The elevation difference between this station and the lowest in Oslo Metro (Stortinget), 478 meters (1,568 ft), is the highest elevation difference within a metro network in the world. The area around Frognerseteren has very little population, but is popular for recreation, with a restaurant and hiking trails or, during the winter, skiing. Tryvannstårnet is also within walking distance although Voksenkollen station is slightly closer.

Rødkleiva is a hill located in Nordmarka in Oslo, Norway. It was taken into use as a slalom hill in 1947 and was used for the combined event of the Holmenkollen Ski Festival eleven times between 1947 and 1963. It hosted the slalom events for the 1952 Winter Olympics, which saw a crowd of at least 25,000 spectators. The Olympic course was 422.5 meters (1,386 ft) long and had a drop of 169 meters (554 ft). The course gradually fell into disrepair and was closed in 1988. The hill has several times been launched as a potential location for a ski jumping hill. The first idea came in 1912; later options to replace Holmenkollbakken resurfaced during the 1930s and the 1970s, but were quickly rejected. With the closing of Midtstubakken, Oslo's normal hill, in the late 1980s, Rødkleiva was again launched as a jumping hill. Vikersundbakken—Northern Europe's only ski flying hill—was in the late 1990s proposed replaced by a new hill in Rødkleiva. The plans received support from the Norwegian Ski Federation, but the municipality and state were not interested in issuing grants and the proposal was finally laid to rest in 2006.
