Having a car along Kongevegen will, of course, give you much more flexibility as it is easier to travel around to the different hikes along Kongevegen. At the same time, you often need to get back to your car so loop hikes are definitely better than hikes where you have to hike back the same way as you hiked in.
Kongevegen is situated along road E16 and you can easily drive there in a day from Oslo(4 hours) or from Bergen(3.5 hours)
If you have 2-3 days and you are traveling by car along Kongevegen we suggest you stop by these adventures.
Spend the first day visiting the old road by Kvamskleiva. This part of Kongevegen is recently renovated to bring back the old road from the 19th century.
On day two visit Borgund Stave Church and Vindhellavegen. Vindhellavegen is a loop starting from Borgund Stave Church so you can park your car there and visit both at the same time. There is also a cafe and a visitor center right by the church.
On day three visit Seltunåsen. Seltunåsen is also a loop hike bringing you back to the car when you are done hiking. This hike takes you through the old road going through Galdane and Seltun, and it covers two types of road constructions as one is built 50 years before the other.
If you have the time drive down to Lærdal which is the endpoint for Kongevegen. This little town is buzzing with life during the summertime and is well worth a visit.
