Interesting to be kayaking in most any fjord, for most are very similar and some not so safe for small vessels such as a kayak. Once in the fjord, other then a passing ship creating a large wake, is relatively calm other then if the wind comes up between the mountains. For those things are really water filled valleys. The mouth of the fjord though is not so good with a tidal change with associated currants. For most often the shores are rock infested and those things will usually dump a small vessel if blown or tossed upon. It is then the occupants can become crab food.
At the moment, I am not sure of the fjord this young man is kayaking for there are just hundreds of such fjords in Norway. But, most of Norway is very beautiful and scenic with mountains and valleys abound. The further inland though, many of the roadways although taken care of, are of gravel and dirt. If a person is very particular about the cleaness of his/her auto, best to stay inland or only on one of the well paved roadways.
There are a great many small fishing villages that have a beauty of their own and an opportunity to visit another culture that is Viking. For it is not unusual to see such small vessels with point bows and sterns for these will ride most any rough waters very well. Whilst riding the rough waters is one thing, the wind is another, and the design of such little boats caught through the wind very well where lesser small vessels will catch the wind and it becomes a problem in those cold waters.
