From Skibergfjellet. A mountain in Hof municipality, Vestfold county.
This mountain has several peaks. From the second highest (632 m) you have a great view of the Oslo fjord (Oslofjorden). All the way to Færder Fyr (Færder lighthouse) in the south, the Swedish coast in southeast and Tryvannstårnet, Norefjell and Jonsknuten.
Southwest of this is another summit called Vestfjellet. This is a little bit higher, 634 m and in fact the highest point in the county of Vestfold.
You have to park like this in the area
About the bike in the tree @blarsern writes that you have to park like this in the area. Because of all the bears wandering around. You don´t want them to chewing on your carbon frame. It´s a long walk down.
