Kolsås

Kolsås is a wooded mountain ridge in the municipality of Bærum, Norway. Geologically, Kolsås belongs to the Oslo Graben area. Its two peaks consist of hard rhomb porphyric lava covering softer rocks, forming steep cliffs to the east, south and west.

The name

An old farm beneath the mountain has the name Kolsberg. The first element in this name is the genitive case of the old male name Kolr, and the last element is berg n 'mountain'. The parish and municipality of Bærum (Old Norse Bergheimr) is probably named after this prominent mountain. The last element in the name of the mountain was later changed to ås m 'mountain ridge' to distinguish it from the name of the farm.

Protected landscape area

The area from Kolsås to Dælivannet is a protected landscape area from 1978 (five square kilometers), with four nature reserves: Skotta, Dalbo, Kolsåsstupene and Kolsåstoppen nature reserve.

Climbing

Kolsås has been a training area for climbers since beginning of the 20th century. Today it is the largest rock climbing area in the Oslo region. The wall Øvre Sydstup on the southern wall has more than 200 climbing routes.

Kolsås (station)

Kolsås is the end station of the Kolsås Line on the Oslo Metro. The station, located in Bærum municipality, comes after Hauger, and is located 17.3 kilometers (10.7 mi) from Stortinget.

The station and line into Bærum was originally not built as a metro line but as the Lilleaker Line, built by Bærumsbanen. The station opened 1 January 1930. It was not until 1942 when the line became part of the heavier metro network. The station retains a turning loop for trams which can only run forwards.

The station is the one closest to the military base Kolsås leir, which was the former home of NATO's Allied Forces Northern Europe.

The station, along with most of the Kolsås Line was closed for maintenance, between 1 July 2006 and 12 October 2014. The station was also closed for over a year between 1 July 2003 and 22 November 2004.
