Fossen

Fossen (“the waterfall”) is Kongeparken's log flume, opened in 2013 as the largest single investment since the park opened in 1986. The ride was originally built by Interlink in 1995 for Peter Pan's Playground, later Adventure Island, in Southend-on-Sea in England, and was rebuilt for Kongeparken by ABC Rides after the English park removed it in 2006.

It has two lifts and ends with a nine metre plunge into the splash pool. Part of the layout is taken backwards, which the park bills as unique in Scandinavia. Children from 90 cm may ride with an adult, from 140 cm on their own.
