Vrangfoss Lock is a UNESCO World Heritage Site. Vrangfoss is the largest lock complex in the Telemark Canal. There are a total of 5 lock chambers with a total height of 23 meters. Vrangfoss got its name because the waterfall was so steep and it was so difficult to transport wood. Before the canal was built, the river passed through a gorge about 2 kilometers long with waterfalls and narrow passages.
A highlight on the Telemark Canal is a nostalgic boat trip on the MS Victoria or the MS Henrik Ibsen.
If you want to watch the ships passing through the lock, you should be at Vrangfoss Lock by 11:00 or 14:00 at the latest. If you want to see both ships in the lock, you can pass the time with a hike to Eidsfoss lock.
