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.

Since then an enormous expansion has occurred, and today Tryvann vinterpark consists of 18 slopes and 11 lifts.

The ride from Oslo city centre to the top of Tryvann takes approximately 25 minutes.

As a result, Tryvannstua was constructed with the purpose of serving food for people travelling in the woods, and that was the beginning of Tryvann vinterpark.
