Constructed back in 19th century, the Korktrekkeren slope is 2,000 metres long and was originally planned to be a bobsleigh track. It has never become a permanent bobsleigh facility, but it still gives lots of joy to people.
Typically one ride takes about 8-10 minutes and the elevation drop is 255 metres. When you reach the end of the slope you get to the Midtstuen metro station and can easily go back to the top back to Frognerseteren stop. Remember to be careful not to loose your sled, or you will have to run 2 km down the slope to catch it.
The rides are free of charge. The only expense is the sledge rent that costs around NOK 100-150 per day. The toboggan run functions only when there is sufficient snow, so check the website before heading there.
