What with all the snowfall here the hills are alive with the sound of sledding. We didn't get the 50-60 cm that other regions of the country did, but there's more than enough snow to slide. The Bullitt did a tour of duty on the park pathways on the way to the inclines.
There was an armada of cargo bikes filled with kids all around the park. Here's a classic Christiania bike with owners watching the action on the steepest part under the castle. We tried it out but preferred the other hills.
There are many creative ways to get to and from sledding involving bicycles.
