A flat and non technical ride with a very wide option next to the wall.
Dogs must be leashed from April 15 to August 15.
An interesting ride along an old fortress built from 1898-1900. There are two options: riders can travel along the edge of the the fortress wall for a wide but sometimes bumpy route, or they can pedal on top of the wall for a better view and smoother going. At the west end, there are some old cannons still in place looking out over the Oslo fjord.
