From Kaupanger the road crosses a tunnel and reaches the ferry terminal in Mannheller,
where there are car ferries across the Sognefjord to Fodnes. Ferries run every 30 minutes and take about 15 minutes to cross the Sognefjord.
From Fodnes it's a 36km drive along the Lærdal valley to the Borgund stave church. This is a black wooden church, originally built between 1180 and 1250. The Borgund stave church is very well preserved and is dedicated to St Andrew. Nowadays it is used as a museum.
Near the church there is Vindhellavegen, a section of the Kongevegen which connects Lærdal with Fagernes. This consists of a number of serpentines with stone walls.
The Laerdal tunnel is 24.51km long and connects the Laerdal valley with Aurland, a small city on the Aurlandsfjord, a side fjord of the Sognefjord. The main reason to come here is to take the road to the Stegastein viewpoint. The road to Stegastein is very narrow, in some sections wide enough for only one car. From the viewpoint at 650m of altitude there is a platform with nice views of the Aurlandsfjord.
